Thx guys!
That "pot" is 1,5kg copper with a single hole in it. Starting nature@-139°C (-140°C cold slow), finishing @-98°C. Pouring LN2 all the time.
For 2k1 and AM3 enough, everything else, lolz

Hello! Didn't measure full load temps but they had to be around 16 - 18 °C for this GPU. Over that it'll fail to complete GT4.

I've got an oportunity to try the new power supply from Enermax. I do want a whole perfect PSU torture rig with ATE (Automatic Test Equipment), AC power analyzer and temperature controlled hot box, but
this time we'll leave that to professional PSU review sites. We'll try it out the OC style. Just like ENERMAX calls this unit, the "SUPER OVERCLOCK EDITION".
You may ask what makes this unit the "OC" edition? It's single +12V rail design, hard wired 24 pin ATX connector, dual 8 pin CPU power connectors and dual 8 pin GPU power connectors while other from the Platimax series (500W, 600W, 750W CrossFireX™, 850W SLI®, 1200W CrossFireX™ and 1500W) are multi rail design and full modular.
For those what want more on single vs. multi rail: http://www.jonnyguru.com/forums/showthread.php?t=3990
View from an overclocker with highly clocked + liquid nitrogen cooled + disabled power limiter + "nda secret" voltage tool or hard modded for oldscool badasses equals do want single rail.
Some pics of the new Platimax:
Platimax series with platinum colour, nice touch. 80 PLUS Platinum, this should reduce your power bill.
What would I like to mention here is the lack of the third 6+2P PCI-E power connenctor. It's clearly listed on the box that it comes with 2 yet the PSU unit has 3 connectors.
Maybe just calculating that most of systems will have a pair number of PCI-E power connectors but we all know a few beasts with three PCI-E power connectors.
I feel no need to comment the specifications, if you are on HWBot, you probably know what these are.
Classic final touch from ENERMAX, CordGuard. It's actually not a bad idea, my pets want the most attention when I'm pouring liquid nitrogen. A power cord is then a nice toy.
Enough chit chat, jump to some overclocking.
Stage 1:
As I had a brand new 3770K that was quite promising when testing under cascade I had to try some 2D benchmarks with liquid nitrogen cooled CPU.
Setup & 2D Results:
Really nothing much to say here, peak power while running wPrime1024W around 400 W. Not really warming the components inside the PSU unit. Let's call this the morning stretching.
Quick try with GTX275 SLI in 3DMark01SE:
Stage 2:
GTX480 SLI + 3770K under cascade
This stage put some load on PSU. Let's call this basic load for that kind of PSU. I would dare to run 3SLI GTX480 setup like this with regular 24/7 CPU and GPU clocks.
While benchmarking 3DMark 11 Xtreme preset maximum power draw from the AC outlet didn't exceed 965 W so I had to use the following setup to really put some stres on PSU.
3770K 4.7 GHz, 1.305 V - cooled by Thermaltake Big Water
Maximus V Gene
GTX480 SLI with EKWB full cover [1.275 Vgpu] - Iwaki MD-30RZ - 2 x 360mm rad with 6 Delta AFB1212VHE
Samsung 830 128 GB + WD 320GB
245 W peltier, cooled with 30W 220V AC pump - 240 mm rad with 2 Sanyo 12V vent
Enermax Platimax 1000W OC
Voltcraft 304 - measuring ambient temperature, botom of PSU heatsink, cold side of peltier (to make shure it's working)
Unitest Hexagon 310 + old laptop for logging the +12V line.
Basetech power consumption monitor.
System was running for 3 hours. In this time it consumed 3.336 kWh.Average power draw from the AC outlet was 1112 W.
Ambient temperature: 27.5°C
PSU heatsink temperature: 37.5°C
Peltier cold side temperature: -19.6°C
As I mentioned in the beginning, I'll focus on the +12V line as it's the most important nowadays, especially when overclocking.
+12V line was recorded for the last 30 min of test. Reading point was the 6 pin power connector on second GTX480.
60 mV peak to peak with overloaded PSU, now you got me Enermax.
At last we'll take a peek at efficiency. As you may notice, I like to be efficient on hwbot
If we take a look at efficieny of PSU, we can also save some money. Especially if we consider, that our PSU won't be outdated like CPUs or VGAs. It'll run for many years.
I compared Platimax 1000W with the following power supplies. Corsair TX 950 and Chieftec A-135 APS-1000C. I really wanted to compare it with Revolution 85+ 920W but I had a
little accident when assembling water cooling. Shure that these power supplies are not in the same price/efficiency/power class but just to make some imput on the differences.
Some calculations:
Difference between the best and worst when loaded: 0,868-0,801=0,067 kW
Pretend that I really do something at work/home or bench
for 8 hours per day. 8*0,067=0,536kWh per day.Current price for electric power: 0,14277€/kWh
Saving per day: 0,536*0,14277=0,07652 €
Saving per year: 365*0,03826=27,9298 €
Of course, you are more than welcome to recalculate for your situation. The difference will be bigger if you are working/benching/gaming more
Power supplies with that kind of efficiency are no brainer for GPU computing people. Electric bill saving, for my case: 24 hours*0,067=1,608kWh per day.
At last, big thanks to ENERMAX for giving me a chance to torture their Platimax 1000W OC.

Congrats!!

My Abit KN9 sucks, on air i had better results than dry ice. CPU was on 5-10*C, NB -10- -50*C and nothing. On DI i can't have even fu**** 400 htt.
Testes two cpu's, 4400+ and 5600+, i have one more cpu sempron x2 2100+.
Any ideas?
CPU cold bug. For higher htt clocks you'll need higher temps.

Tnx Karl!

Done.

is it possible to knock out? that is what i wanted to do, but it seems like it was processed and then cooled and wont come out. But i also know you guys do crazy things that i wouldn't think are possible.
gangsta.
I tried to knock it out but no success, maybe with heating the aluminium part.
Did it the hard way:

Works great as a NB pot, or CPU pot (<30W TDP)

Hi!
Applied wrong picture, I'll edit.

True, true. Sad but true

Nice one, have fun with it!

Tnx m8!
MIVE killed two of my CPUs, really hope that next one will be a tiny bit better

Diabolo 80, nice dog!
Dealing with our customs for the past 9 days, finally got it.
Thanks XtremeLabs and Inno3D!

It can be, I had one 3770K with exactly the same symptoms. Could boot only with memories in first and/or second slot.
