Antec 1200W non OC is the highest model available in my country.

I want to buy it to replace the Corsair HX1000 for Gulftown benchmark (LN2, for sure).

Does the bigest difference between us is Fan Control Knob/+12V Voltage Control Knob, not the clock of 980X?

 

I tried all psu already. Corsair still cannot pass 5.7G cpu test. I change psu to antec 1200. Everything is fine. 6G pass cpu test so easily. I have no any idea why psu is so important for gulftown. Maybe you should ask nickshih why antec's psu can handle gulftown easily.

 

and any PSU recommend for 980X?

 

Here is my best result with Corsair HX1000.

 

 

 

sorry for broken English.

Thanks.

At high clocks and Vcore, Gulftown can pull over 500W of power.

Since most modern boards are designed so that most of the power CPU gets through the 8pin EPS, you'd need a unit that can give over 40A of current on +12V rail that goes to the 8pin EPS. (which means that all 18/22/24A multi-rail designs are to be thrown out).

Gulftowns are also very sensitive to voltage output quality.

 

What to recommend?

I'm not a big fan of Corsair PSU, but their HX850 (70A singlerail) , TX950 (78A singlerail) and AX-series seem to do the job well, just tell us what brands you have available...

 

Personally, I use a very old Silverstone OP1000 (Seventeam built 80A singlerail). Having compared with many "popular" models seems to be best PSU i've tried so far.

i second sam's single rail suggestion...

 

we had one test that pulled 750w from the wall...just a cpu test on a 980x ..very power hungry cpu

At high clocks and Vcore, Gulftown can pull over 500W of power

Then how did the Antec 1200 manage to power two Gulftowns and four GTX480?

First I need to find a good 980X, and then I will test it with the Antec 1200 for max clocks, and then I'll try the same with 10 different PSUs from all categories and brands...

most power supplies can be overloaded and still work ok...some server grade psu like the antec tpq1200 is very good...

I use the antec 1200, non oc.. probably going to pick up an oc, need it for the sr2..

Running 4 GPUs almost always necessitates a second PSU to keep from overloading the PSU. As suggested above I'd grab a second PSU like the HX850 and use it for the CPU and use the HX1000 for the two GPUs.

I know about the overload. But if the calculations are right it's overloaded more than 50% above it's wattage!

Outstanding new PSU.

its rated 1200w

 

1700w from the wall...considering efficiency at max load...say 85% ...its only silver rated...

 

actual load = 1700 x 85% = 1445w dc

 

overload percentage =( 1445/1200 - 1 ) x 100 = 20%

1700w from the wall...considering efficiency at max load...say 85% ...its only silver rated...

 

Can't get 1700w from the wall on a 120VAC line in the US. Only 1400w max before it pops a 20 amp service breaker.

I've seen a PSU with two power cords. Maybe in the near future it will be more common. Luckily, that's not a problem is Russia. But if you take an old house, playing with a lot of wattage can make your wires in the walls burn

You bet.

i was talking about nickshih..he's in asia....guess what the voltage there is

And with no links or quotes in your post, we're supposed to know this?

I know what the voltage is in Asia BTW. :rolleyes:

you're so smart
