CPU Full Speed - 130W No matter OC to 4G or 4.6G, the standby power consumption is lower than 70W. The full speed gap is bigger, but the highest is around 130W. It’s very green platform. If CPU works at default 3.2GHz, the power consumption will be much lower. Finally, pull CPU voltage to 1.488V, 655K air cooling can OC to 5GHz. CPUZ Certify Intel Core i5 655K OC 5G / windwithme Early Jan, I OC Core i5-660/661 CPU to 5GHz and now 655K also can OC to 5GHz. And using 655K 5GHz to enter OS, the voltage is lower to 1.488V. You can see Intel CPU yield rate is improved. Since Intel launched LGA 1156 in early 2010, 2 Cores CPU started to built-in GPU. It becomes a new choice of ITX market, price and performance. CPU combination is more vary. There are Core i3-530/540, Core i5-650/660/661/670/655K. The price is also more flexible for different budget. For MB, early this year DFI launched LANPARTY MI P55-T36, and few months later ECS announced H55H-I and GIGABYTE GA-H55N-USB3. These 3 models all break the old barrier and image for this kind of products. They all emphasize OC and rich BIOS items. The performance is almost same as Micro ATX or ATX MB. No matter NooteBook or Desktop PC all go for smaller form factor. Like PC, the normal size is ATX and smaller goes for Micro ATX. Now, MB starts to move to ITX, and more MB brands provide the products. Also Intel pushes new series Core i3/i5 CPU, 32nm manufacture and built-in GPU technology. This year, ITX visibility is higher. I hope ITX products can be more popular and more brands to join this competition. The customers can enjoy smaller PC which saves home space and good PC performance.

CrystalMark 2004R3 => 217668 CINEBENCH R11.5 CPU => 3.83 pts CPU(Single Core) => 1.55 pts PCMark Vantage => 15924 After changing to high end CPU cooler, OC to 4.6GHz and pass the benchmark are not big deal. It pull high the performance 10~15%. Due to 655K is 2 Cores, the OC range is higher than 4 or 6 Cores CPU. The perivous review of 660/661 also can achieve 4.6GHz. Of course, you can see the strength of 32nm manufacture. It really help to lower the temperature, power consumption and pull the CPU clock. DRAM bandwidth test - DDR3 1600 CL8 8-8-24 1T CPU OC 4GHz Sandra Memory Bandwidth - 15180 MB/s EVEREST Memory Read - 12050 MB/s CPU OC 4.6GHz Sandra Memory Bandwidth - 15232 MB/s EVEREST Memory Read - 12125 MB/s You can see the difference between 655K and Core 2 Duo structure by the test result. In the past, in LGA 775 platform, the higher CPU clock means higher DRAM bandwidth. LGA 1156 built-in Memory Controller in CPU, so the CPU clock doesn’t impact DRAM performance much. However this design make LGA 1156 basic DRAM bandwidth is 20~30% higher than LGA 775. This is why even yopu pull LGA 775 CPU clock to extremely high, the bandwidth still cannot catch up LGA 1156. Temperature System standby - 40~41 CPU Full Speed - 71~73 Intel Burn Test v2.4，Stress Level Maximum The standby temperature is not high and full speed at 73 is also acceptable. If you use this cooler, CPU temperature will be higher inside the chassis. But it still can long time use under acceptable temperature condition.

Some hi-end SSD almost reach the SATA2 300 MB/s bandwidth. I believe the market will be even booming after SATA3 being more popular. ITX platform uses CORSAIR F60 can shorten the system boot, open application and access files time. Now, I use open air to test the higher OC performance.

USB 3.0 chip is NEC D720200F1 As per the components and spec, the user price is around 4000NTD, about 127USD. Although there are only 3 ITX MB in the market, after comparing, H55N-USB3 C/P value is quite good.

However if you have system fan, it will be great help for internal heat flow. As H55N-USB3 design layout, it causes ElementQ Power/Reset cables are not long enough. Although MB and CASE are good C/P products, but you should know such detail before buying. Real installation test, it should close the chassis and test how long can run normally under OC condition.

The full speed temperature is around 70 degree C. The temperature control is also acceptable. If the chassis is opened, using the original cooler can OC to 4.3GHz. The full speed temperature is around 90 degree C. I personally hope to test OC in chassis to find the balance between stable, temperature and performance. After many OC combo test, 4GHz is the most stable condition inside complete close for long time usage. Currently, the best tool to enhance the system performance is SSD. With CORSAIR FORCE SERIES F40, I hope it can have better performance in this ITX system. Size is 2.5” and ID is F60. The highest performance is 285/275 MB/s. Random 4K writing performance can reach 50000 IOPS which improve the 4K writing issue in past SSD.

The normal image of ITX platform for users is hard to find in the market, price is high and old generation chipset. Even it’s the NoteBook CPU socket or SO-DIMM design to make ITX platform price go even higher. Intel launched 32nm Core i3/i5 CPU early this year and also launched H55/H57 chipset at the same time. Also, many MB manufacturers launched LGA 1156 ITX MB. The price is lower than past ITX MB. New spec ITX MB uses PC spec CPU and DDR3 that makes ITX product be more easy to use and cheaper. This review is to introduce the high performance ITX platform with latest products. First of all, the CPU is Intel latest unlocked version, K series, Core i5 655K. Left side is product manual and right side is 655K CPU. The special thing is 655K and 875K don’t bundle original cooler. Intel suppose the unlocked version CPU users will choose better performance cooler. The clock is 3.2GHz supports Turbo Boost technology. The max speed is 3.46GHz. Physical 2 Cores with Hyper-Threading can achieve 4 threads, called 2C/4T. 32nm manufacturing, L3 Cache is 4MB. CPU back design can see the version and different design. The built-in GPU clock is 733Mhz. MB uses GIGABYTE H55N-USB3 2oz cooper PCB, USB 3.0, 3X USB Power, and On/Off Charge are advantage features. 2 X DIMM DDR3 support 800/1066/1333/1600(OC), and maximum capacity is 8GB. 1 X PCI-E X16 for user to install Low Profile VGA card. Realtek ALC892 supports 7.1 channel and High Definition Audio technology. 24 + 4-PIN power connector. 4X blue SATAII support by H55. It’s SATA2 and no RAID function. IO 1 X DVI-D 1 X HDMI 1 X D-SUB 2 X USB 2.0(Yellow) 2 X USB 3.0(Blue) 1 X eSATA/USB 2.0 combo (Yellow) 1 X S/PDIF fiber output

Another desktop PC test is in AMD platform. Using GIGABYTE 890FXA-UD5, the SB is SB850, the most hi-end AMD Chipset so far. It also supports SATA3. Supports ATI CrossFireX, On/Off Charge, USB 3.0 with 3X USB Power Test Configuration CPU: AMD Phenom II X6 1090T Black Edition MB: GIGABYTE 890FXA-UD5 DRAM: CORSAIR DOMINATOR-GTX3 DDR3-2400 VGA: ATI Radeon HD 5830 CrossFire HD: CORSAIR CSSD-F40GB2 Raid0 POWER: ANTEC HCG 620W Cooler: Thermaltake V1AX OS: Windows7 Ultimate 64bit ATTO DISK Benchmark 64k above test can achieve reading at 446.3 Mb/s and writing at 445.2 MB/s. EVEREST File Benchmark64k above test can achieve over 400 MB/s. EVEREST Linear Read Average 422.3 MB/s CrystalDiskMark reading at 240.9 Mb/s and writing at 106.6 MB/s. AMD Raid0 has no “Write-back cache” item, so the performance is lower. I hope AMD can add in this feature in Raid tool to enhance own chipset performance. Of course, if we also disable “Write back” in Intel platform, the performance will be similar. I also have some friends use SSD as NoteBook system drive and use 2.5” external HDD as data drive. For desktop users can have higher performance with SSD as building Raid0 by 2 pieces 40GB SSD. The performance will be much higher than single 80GB. However, the previous SSD version has lower performance issue after using for long time. The most new versions SSD all support TRIM to solve this issue, but it’s only for single drive now. Due to Matrix Storage Manager doesn’t support Raid0 TRIM instruction, the performance dropping issue is still exiting. The solution is clear SSD Raid0 mode and all data. Then re-build the Raid0 to recover the original performance. For Raid0 not support TRIM issue has none solution now. We only can expect Intel launches new Matrix Storage Manager to support it. Just can let Intel chipset with SSD Raid0 users to really enjoy Raid0 performance and worry free for performance dropping issue. Intel SSD product has very high level standard. The 4K writing performance is almost the best. CORSAIR F40 uses Intel 29F32G08AAMDB and new controller, SandForce SF-1222TA3-SBH. Except the high 4K writing performance, it also improves the overall performance of Intel NAND FLASH IC. Force series can be the new generation high performance SSD spec. It’s also the key factor to ramp up the SSD market share. CORSAIR Force series has 40/60/80/120/160/240GB. The users can buy by budget. More SSD capacity provides more flexibility. Force 40GB price is around 125US. Comparing to the other brands, the price is not too high. There are more and more controllers in the market. It also improves the performance. At least the different chipset has different strength. In the future, the price and capacity still impact the SSD coverage. I do want to see it happens soon. Recently, I got a DC - Canon IXUS 200IS, official from Taiwan disti. If I have time, I will make a preview. The content has outlook and experience sharing. Thanks for your time to read this SSD review by windwithme. It also post in my blog.WIND'S 3C Welcome you to come and comment.

CORSAIR F40 in HD Tune Pro test also has very high performance. Both read/write are all over 500 MB/s which are very impressive transfer rate. The seek time is below 0.1ms and even achieve 0.017ms. This is also very outstanding. ATTO DISK Benchmark can also achieve over 560/530 MB/s, read/write performance. It really shortens the PC access time.

The others like CrystalMark、SiSoftware Sandra are also similar. The most surprise is some items of AS SSD Benchmark and FDEBENCH didn’t reach the highest performance. After repeating test and check the internet, I found it is caused by controller chip. SandForce SF-1222 in other SSD products is also having this issue. CrystalDiskMark 50/100/500/1000MB comparing test According to the different file size, you can see the improvement of CrystalDiskMar Seq performance. F40 high light point is having better transfer rate in smaller file. This is normal for high performance 4K file type SSD.

It’s also possible the limitation of SB. However, the benchmark is still over 68600. I will test with RAID card to compare this in the future.

SSD full name is Solid-State Drive. It’s new booming hardware within 2 years. It really enhances the PC/NB transfer performance. The main reason is SSD using NAND Flash instead of diskette design. SSD normal capacity are 32/40/64/80/128GB. Recently, SSD market price is dropping a little bit. The main reasons for users to buy are transfer performance; seek speed, anti-shock ability and MTBF. Especially for NoteBook users, SSD is also lower power consumption and lighter. However, SSD price and capacity are still the key factors to impact the selling ramping speed. Related to SSD products, USA brand, CORSAIR, also put lots of efforts. They have 6 SSD product lines. Per performance, it divides into Force/Nova/Reactor/Performance/Extreme/Legacy series. This review is CSSD-F40GB2, belongs to Force series. It has 3 years warranty. CORSAIR F40 SSD position is similar to Intel X25-V 40GB. This review will focus on RAID0 in PC. First to check the packing, CORSAIR FORCE SERIES F40 Product size is 2.5”, code is F40, and the highest performance is 280/270 MB/s. Random 4K writing performance is 50000 IOPS. 4K writing performance is the weakness of most SSD. Black metal shell and brushed finish surface look great. Official weight is 80g which is lighter than 2.5” HDD. The website showed the controller IC is SandForce SF-1222TA3-SBH. MLC NAND FLASH is Intel 29F32G08AAMDB, total 10 pieces 4 GB chip. The sticker above is warranty notice. The warranty will be invalid if it’s broken. SATA supports SATAII which is for PC or NB. This review uses desktop with different SB chipset to test RAID0 performance. I believe this combination is very popular now and using SSD for booting drive. And use big capacity 3.5” 7200rpm HDD for data drive. Desktop uses Intel platform, GIGABYTE X58A-UD5. SB is ICH10R, the most high end Intel chipset currently. I use it to test performance. Built-in USB 3.0 and SATA3, 2 latest MB technologies.

ECS Black Series P55H-AK Advantages 1. High-level P55 motherboard products are rare in the market, and the external appearance and packaging are both well-done 2. Internal NVIDIA NF200 chip, 3D expanded to 3-way NVIDIA SLI / ATi CrossfireX 3. Uses newest USB 3.0 and SATA3 chips, improving the highest bandwidth for motherboard transmission interfaces 4. Added PLX PEX 8608 chip, increasing PCI-E overall bandwidth 5. DDR3 bandwidth performs better, excellent CPU external clock overclock range Disadvantages 1. CPU voltage values are at default during standby mode 2. DDR3 2000+ stability has room for improvement 3. USB 3.0 performance sometimes drops Efficiency ★★★★★★★★☆☆ Materials ★★★★★★★★★☆ Specs ★★★★★★★★★☆ Appearance ★★★★★★★★☆☆ Price ★★★★★★★☆☆☆ The ideal CPU to match the LGA 1156’s P55 chipset would be the i5 750/760 or i7 860/870/875K. After Intel lowers the price of CPUs, this platform’s C/P numbers will exceed that of the highest level X58. In addition, every motherboard manufacturer is releasing quite a few P55 motherboard products, giving consumers many options. Prices range from around NT$3500 (around US$110) to around NT$10,500 (US$330). I suggest that before buying the LGA 1156 you look at your budget, and then buy a P55 motherboard product that suits your needs. In terms of design and components, the P55H-AK meets the standards of major three-channel motherboard products, which is something that is definitely worth noting. Motherboards being sold for around NT$9500 (US$298) now are high-level P55 motherboards. If the prices can be pushed down a little, I believe it will increase C/P values, and could become more acceptable to more consumers. Since ECS has not entered the field of high-level overclocking products for very long, there are a few details that could be done better. For example, increase BIOS options, or strengthen BIOS stability during extreme overclocking; this would increase the level of performance. ECS is a major global motherboard manufacturer; if they can establish themselves in high-level overclocking products; this would greatly improve their brand image. When purchasing a motherboard, many consumers look for an option outside the major three manufacturers, and ECS is certainly worth consideration. I hope that for future high-level products, like the modified X58 or the yet-to-be-released P67 chipset, ECS will be able to produce even better products.  This article is also posted in my blog: WIND'S 3C Welcome 3C fans to drop by.

PCMark Vantage => 16381 P55H-AK takes the CPU overclocking to 4.2GHz after passing numerous kinds of software stability testing, while the power requirements are about the same as other P55 products. In conjunction with the i7 875Kexternal clock, 210MHz can be achieved stably, which is a pretty good performance for the P55 level. In terms of CPU voltage, we can only get statistics for default voltage during standby mode, and can only achieve the voltage values of user-set BIOS settings at full speed. During relatively larger overclocking, some negative effects was still seen; I hope ECS can improve this in the future. DRAM Efficiency Testing DDR3 1680 CL8 8-8-24 1T Sandra Memory Bandwidth - 21889 MB/s EVEREST Memory Read - 20980 MB/s DDR3 2000 CL9 9-9-24 1T Sandra Memory Bandwidth - 25067 MB/s EVEREST Memory Read - 21868 MB/s DDR3 bandwidth testing showed better results than other P55 motherboard products, perhaps because the default parameters were tighter, or perhaps because the OEM fine-tuned it better. The P55H-AK DDR3 bandwidth performed about as well as the LGA 1366 three-channel bandwidth tested. 3D effects Testing Three GTX 260 were used for testing, P55H-AK is one of the few that support NVIDIA 3-way SLI P55 products 3DMark Vantage => P28536 CPU SCORE => 52795 GPU SCORE => 24746 Street Fighter IV Benchmark 1920 X 1200 8XAA => 132.97FPS Devil May Cry 4 DX10 1600 X 1200 8XAA => 109.63/97.68/108.19/125.07 fps Final Fantasy XIV 1920 X 1080 => 4008 Star Craft II: Wings of Liberty Settings at High - 62 Lost Planet 2 DX9 1920 X 1200 TEST A - 44.9 fps DX9 1920 X 1200 TEST A - 40.1 fps 3DMark Vantage and Final Fantasy XIV both support 3-way SLI, so the numbers are much higher than the single-chip GTX260. However, the testing of other games, which did not support SLI, showed that they were unable to take advantage of its functions. For many games, not only is there the problem of GPU SLI/CF support, but there is also a great deal of room for improvement for supporting four-core (or more) CPUs.

Settings include two user profiles so that users can save their overclocking settings. CPU-related Technology Options C1E is a power-saving, frequency reduction function; when CPU usage is not high, it will automatically lower frequency and power PC Health Status The power supply functions and number of options in the P55H-AK’s BIOS isn’t bad, though if they added some power supply options it would be even better. The above was my personal opinion, as I am using the CPU/DDR3 set at 210/1682; those consumers with good constitutions or similar hardware sets could consider using these settings. I hope this helps those of you who need to overclock.

Several newcomers have entered the motherboard market in recent years, and thinking back on it, I actually miss the old days of intense competition between all the various motherboard manufacturers. Nowadays consumers see fewer and fewer choices, many of which belong to the three major motherboard manufacturers. At the same time, it seems that motherboard prices are getting higher and higher; if there were a greater variety of manufacturers vying for customers within the market, consumers would be the true winners. ECS has returned to the Taiwan market this year, and has put a lot of effort into giving its new motherboard products some exposure. ECS seems to be on-par in terms of pricing, while ECS’ current OEM line of products are making strides in the high efficiency and overclocking realms, resulting in an additional choice for high-level motherboards. Intel has consistently set the LGA 1156-spec P55 chipset at the mid- to high-range portion of the consumer market. Compared to the LGA 1366, the P55 lacks SLI support, multiple tasks PCI-E bandwidth support, and DDR3 technology support. However, some high-level P55 products are able to connect external chipsets to strengthen the areas that are lacking. The ECS P55H-AK I obtained is one of the few P55 products with high-level specs, which I will discuss more below. First, looking at the exterior appearance of the P55H-AK, you notice that they use the less common colors of black, gray and gray-blue. The product looks different from other motherboards since the colors used are very similar to one another, resulting in a stately, solemn feel without seeming to overbearing.

The VGA card is always the one of the most popular market of the PC components, lots of the customers are all targeted on gaming purpose. Moreover, the largest part of the VGA users is focused on the models under US$100, which is also the basic market. But there are still some entry level models under US$ 60, the models are suitable for the users who can not be satisfied with the built-in on board GPU and would like to have independent VGA card. But at the point of my view, except the budget issue, if users would like to choose an entry level VGA for the PC in order to get better 3D performance, I think the best solution for the better C/P rates is to choose the VGA between US&60-US$100. ATI provides multiple solutions in entry level and middle-end VGA cards, there are 3 different models with good performance for the price under US$100, the highest on is the previous generation Radeon HD 4850, the cheapest one is the Radeon HD 4670. The weakness of the “4850” is its higher power consumption and the dimensions are also larger. And the 3D technology of “4670” is not as new as “5570” supports, and the dimensions are not available for the smaller PC. For these 2 models listed, ATI 4850/4670 VGA both belong to the promotional models with higher C/P rates during the gap of the 2 different generations. The price of ATI Radeon HD 5570 is between these two models, and which is designed with newer technology and using advanced process, but I think the major advantage of ATI Radeon HD 5570 will be to use for the smaller PC mainframes. In the recent years, no mater PC or NB, the designs of the outside dimensions are getting smaller and smaller. At the PC end, Micro ATX has been popular for many years, but there are many kinds of Mini-ITX models came into the market this year. So it’s quite important to have high performance & low power consumption for the model with Low Profile dimensions in the new developing market. It was hard to find one Low Profile VGA with good 3D performance on the market before ATI Radeon HD 5570 released. But after then, ATI Radeon HD 5570 has increased the strong power of competition for ATI. It has better 3D performance than “4670” and it might be very possible to become the king of performance and efficiency in the field of Low Profile size. And we also hope that ATI is able to release more Low Profile size VGA cards to have more choices for the users who love smaller PC mainframes.

GPU OC 745MHz/1133MHz System Standby - 102W GPU Full speed - 169W The default & over clocking settings all have no additional power consumption in standby, the entire PC keeps at around 102W. When GPU full speed , the over clocking might increase around 18W power consumption, but the efficiency also increases around 20% more, so the range increased of the power consumption when over clocked is also quite reasonable & acceptable. Thermal Testing GPU Default 650MHz/900MHz System Standby - 50.5 GPU Full speed - 61.0 GPU OC 745MHz/1133MHz System Standby - 51.5 GPU Full speed - 64.0 The ambient temperature is at 33 degree, no mater with over clocking or with default settings, the standby temperature shows stable, and it just increases 3 degree when over clocked. So it should have some help a lot by using 40nm process chipsets to control the thermal for “5570” The last, it is the one of the hottest 3D games at the moment - StarCraft II : Wings of Liberty Setting page GPU Default 650MHz/900MHz Default - 49 High level settings - 40 GPU OC 745MHz/1133MHz Default - 62 High level settings - 47 Even we keep the StarCraft II resolution at 1920 X 1200, there is still 30/fps smooth performance, we recommended not to adjust the 3D effects too high, otherwise it might cause a little bit lag during the game. But in the high resolution with StarCrafe II, which can still be qualified with the high loading of StarCraft II, that means the 3D performance of “5570” is still higher than standard.

3DMARK2006 => 10007 3DMark Vantage => P5363 CPU SCORE => 13456 GPU SCORE => 4467 The performance of “5570” shows quite good in the stable over clocking range, the over clocking efficiency increases a lot compare with normal. With 3DMARK2006 & 3DMARK VANTAGE testing programs, the efficiency increase 20% up by 3D games.

But if users adjust the 3D effects too high, that might cause a little bit lag in some games, by this situation, users might need some higher grade VGA cards to work it out. For the lower-cost level VGA Card, the performance of “5570” is quite well among the 3D effects. Power Consumption GPU Default 650MHz/900MHz System Standby - 102W GPU Full speed - 151W

The main board I am using for testing is ASROCK 890GX Extreme3, the mean feature is the “True 333 function”, USB3.0 / SATA 3.0 & E-SATA 3 can be performed at x16 full speed. In the early stage, the ASROCK 890GX main board is one of the few models which can break out from the limitation of supporting multi-core CPU of the AMD SB850. South bridge chipset is AMD latest model SB850, which supports 6 x SATA3 devices, including RAID 0, RAID 1, RAID 0+1 & RAID 5. The North Bridge chipset is AMD 890GX chipset, which is integrated with AMD Radeon HD 4290 VGA chipset. CPU is designed with V8 + 2 Phase, supports the highest 140W CPU which makes the stability of the entire system much better.

The Radeon HD 5XX0 series is the latest generation of all ATI’s product lines, the main features of which are using more 3D technology and more advanced process of the chips. Plus, the product roadmaps of ATI and AMD are quite similar. The products are all built either with higher C/P rates or with variety of choices for users to make the purchase by their budget easily. There are several kinds of product lines on the PC market: 5900 / 5800 / 5700 / 5600 / 5500 / 5400, which brought ATI new series VGA card a very good comment from the market. I once shared an article about ATI Radeon HD “4670” at the end of 2008, and it turned out that based on the C/P rate, the model was very popular on the market. We can see that from the pricing and position of the product, the new generation ATI Radeon “5570” looks like the previous one “4670”, and also seems “5570” is going to take over the lower cost level of VGA from “4670”. The particulars of the “5570” are including supporting updated Direct X 11, ATI Eyefinity multi-screen technology and ATI Stream technology. First, let’s take a look at the externals of ATI Radeon HD 5570, which is built with a smaller short-card design, means which can be modified with low-profile short bracket, then put into smaller size PC to increase the 3D performance, although one D-Sub connector could be missing. From the rear, we can see that there is a metal bracket to hold the heat-spreader on the front side by 4 screws on the rear. Built-in GDDR3, there are total 8 pcs. of Samsung memory chips on the both sides of the PCB. Frequency is 900Mhz, means it should be DDR3 / 1800. The total capacity is 1024MB, it should be enough to support most of the usage in any kinds of conditions. The heat-spreader is so quite during the operation, no noises, copper made looks very pretty. From the left side, we can see all components “5570” is using, and also with the very dense circuit design. ATI has a very good standard in using the materials & components from the generic PCB design. Since AND & ATI were combined several years ago, we can find AMD brand name on ATI products nowadays. “5570” has built-in D-SUB, DVI & HDMI three different kinds of output connectors. We can see the ATI “5570” chipset is MADE IN TAIWAN after we removed the heat-spreader. The heat-spreader is designed with a large copper base to use for heat spreading, and the quality of the thermal paste also looks very good.

System Temp. Fluctuation CPU Voltage Fluctuation While it’s in standby mode, the voltage stays at around 1.38V, and while the CPU is running at full speed, it stays between 1.36~1.37V. The voltage fluctuation range of CPU is majorly dominated by the voltage features of M/B. 3.3V The highest point measured is 3.26V and during the test, it majorly fluctuates between 3.20~3.22V, making the fluctuation ratio around 1.84%. 5V Falling at the range of 4.93~4.99V; the fluctuation ratio is around 1.20% 12V The highest point measured is 11.92V and during the test, it majorly fluctuates between 11.19~11.43V, making the fluctuation ratio around 6.12%. According to the test data released in 80Plus website (at 115V): The power conversion efficiency of E7 600W is 83.01% and in 80Plus website, it shows that the actual power converted from 720.20W is 597.86W. During my test, the peak wattage, 811W, was converted into an effective power of 673.21W (at least 12% higher than the nominal wattage, 600W). The fluctuation rates of Straight Power E7 600W respectively at 3.3V and 12V are both around 1.9%, making it quite a good performance. 12Vstarts to fluctuate violently after OCCT starts to run at full speed. The fluctuation rate is roughly around 6.12%. In overloading situation, 12V fluctuated bigger. The items here are measured by a more accurate meter. In standby mode: 5V is measured at 5.06V, higher than the 4.99V measured by the M/B. OCCT running at full speed: When the voltage range is around 5.12V and OCCT is running at full speed, the voltage measured is higher than those measured in standby mode. In standby mode: 12V is measured as 11.96V, which is a bit higher than the 11.92V measured by M/B. OCCT running at full speed: When the voltage is around 11.67V and OCCT is running at full speed, the voltage measured is 0.29V lower than that measured in standby mode. Here is the status of 12V when the system is running at full loading When the system loading is at 600~700W, the voltage displayed by Power Angle is 11.72~11.75V, when the loading is at 700~800W, the voltage displayed is 11.70~11.72V and when the loading is above 800W, the voltage displayed is 11.67~11.70V. Based on the data mentioned above, we could realize the 12V performance of E7 600W is still quite stable. The performance of 5V & 12V are much better than the fluctuation result measured by OCCT along with M/B. It’s particularly clear while the fluctuation rate of 12V in OCCT is 6.12%, the rate measured by meter is only 2.42%. Conclusion: Advantages 1. Artistic color box design of the new E7 version of Straight Power 2. Unique case coating and fan guard design 3. Certified by 80Plus Bronze & Active PFC 4. 100% Japanese capacitors & SilentWings FDB Fan integrated (only 17dBA) 5. 5-year guarantee provided, brand new PSU replacement for RMA within540 days, free RMA receiving/delivery for RMA within 3 years Disadvantages 1. It would be much better if PCI-E 6 pin could be extended to 4pcs 2. The design would be much better if 12V could be changed to only 1 rail. Efficiency ★★★★★★★★★☆ Material used ★★★★★★★★☆☆ Spec. ★★★★★★★★☆☆ Appearance ★★★★★★★★★☆ C/P Ratio ★★★★★★★★☆☆ You could still find the advantages of new E7 version in the non-CM series of Straight Power, such as the honeycomb ventilation holes on both sides, sharp case edges removed to better protect the safety of users. Of course, the long MTBF and low-noise level of the exclusive SilentWings FDB fan integrated also serve as great advantages Actually, I haven’t conducted any tests for the part of the wattage higher than it’s nominal spec. This time, I happened to have a platform capable of running at full loading (over 800W) and it allowed me a great chance to compare the difference. When the loading was around 770W~810W, the rpm and CFM of the fan were both increased without making obvious noise and the body temperature of the Power Supply was around 60 Celsius. In terms of these two aspects, I think you can say the PSU is quite excellent. In terms of voltage fluctuation, relatively, the fluctuation is much less in 3.3V and 5V. Though the fluctuation of 12V is a bit higher, after being measured by a meter, the fluctuation ratio is actually only 2.2%, making itself quite a great point/performance in a 600W PSU loaded a lot above 600W. The end user price of be quiet! Straight Power E7 600W in the market is around 3,990 NTD, roughly equal to $124 USD. E7 600W (non-CM version) is around 500NTD lower than E7 580W (CM version) launched to the market earlier. The two models of new E7 non-CM version (500W & 600W) are capable of increasing the C/P value of E7 version. So, if an end user is taking non-CM power supply into their consideration while making a purchase, Straight Power E7 might be quite a good alternative since its C/P value is relatively quite high. : ) This review also post in my blog WIND'S 3C Welcome 3C lovers to visit and advise.

GTX 260 SLI is used for the review in order to reach the utmost 3D efficiency. Also, while at full loading, the CPU could reach power consumption as high as up to 811W; though it was only charged by 110V, still it has reached a level much higher than 600W loading.

E7 version of be quiet! Straight Power series is the latest version launched by BQT. The models from earlier E7 version are 480W, 580W and 680W. These 3 models are all cable management (CM version) power supplies and surely their prices are a bit higher because of the relatively costly CM design. Straight Power also has its non-CM version in the market, including 500 and 600W. In terms of selling prices in the market, their prices are surely a few hundred bucks lower than that of E7 CM version. The focus of new E7 version launched this time is on 80+ Bronze Certification and the SilentWings FDB fan integrated. This new series not only is compliant to Rev. 5.0 of Energy Star and the power consumption needed in standby mode is less than 0.5W. As for its cosmetic part, the point lies in its brand new style. The case used this time is quite different from be quiet! typical image in our mind. We’ll introduce more of the case in the following section. Here is our star, Straight Power E7 600W. The color box design of E7 version, with less different color combinations, looks more elegant. Contents Multi-Language User Manual, Cable Ties, Screws, Power Cord. Straight Power E7 600W Dimensions: 160mm X 150mm X 86mm The coating is “finger-print resistant”, leaving the case a neat touch.

For my experience of light commercial NoteBook, X201i use dual speakers are quite good already. Using 2M pixels WebCAM, I found the color and detail are quite good. It’s almost same as the real theme. If the luminance is not well, the noise will be higher. ThinkPad X201 is a good components, features and performance NoteBook. Especially lowest price one, X201i, is more attractive. The price is around 29000~38000NTD as different specs. It’s around 900~1185USD. Compare to the other NoteBook brands in the same price segment, you are hard to find the same product to compete. I think in this price segment, ThinkPad X201i is in really good position to gain the market share. Many people ask me what is the key factors to choose a good NoteBook? What brands or models are better quality and performance? Then I will ask that are you carrying out very often? If yes, please choose below 1.5Kg~1.6Kg products. If not, just pick whatever you like. If you need to carry out your NoteBook, I recommend the weight is your first priority to consider. Just for your reference. Small dimension and light NoteBook is the mainstream product. Even in DeskTop, it’s getting smaller as well. In the past, Micro ATX is the mainstream spec for small PC. Recently, Mini-ITX, the smaller form factor, is getting more and more popular. In the near future, I will share one article about Inte Core i5-655K/GIGABYTE H55N-USB3/SEED Case high performance MIni-ITX PC. I hope it can provide you some ideas of small PC. Finally, I attach the Spyder2 color correction file for all X201i users.
