Upgrading my system with the following components:

Intel i7 980X
Evga GTX 580 Hydro Copper 2 FTW SLI
Water cooled

Planning on doing moderate OCing

What would be your recommended PSU?

Currently looking at the following:

Corsair 1000HX
COOLER MASTER Silent Pro Gold 1000W
Antec Truepower Quattro 1000W

Suggestions?


Thanks

of those three I would go with the corsair based on HS review of it

"In summary Corsair HX1000W is a practically flawless 1,000 W power supply clearly targeted to users with three or four very high-end video cards and several hard disk drives. Of course if you are building a more modest system with only one or two video cards, you should buy a more inexpensive product, which will give you a better cost/benefit ratio."

but any of those three is more then enough power for you all are good PSU.

I've had 2 different units of the Antec TPQ 1000W and have been unsatisfied with both. 1st one had a bad RAIL that refused to power one of two 4850's (hard wired pci-e connector) 2nd one made a whining noise.

Had Antec send me the CP1000 since I had an Antec 1200 case. That one was fine but didnt supply enough amperage to the 12v rails. the tpq1000's innards are supposed to be made by flextronics which is supposed to be a good company.

Since then, moved down to an xfx with innards made by seasonic i believe.. been happy.. maybe go with the corsair in my opinion. great customer service, solid huge 12v rail.. you won't regret it if you're willing to spend money on a quality PSU

Thanks for the responses. I think I've settled on the Corsair... but then I found the Corsair AX1200.... *drools*

I know it's probably way more than I'll need but the reviews make it sound even more perfect than the 1000HX. Although I don't really like the fully modular design or the single 12V rail with that much current running through it. That >90% efficiency is very attractive though and it is a newer psu.

Also found the Enermax Revolution 85+ 1050W, which some reviews are showing as better than the HX1000.

Probably still get the 1000HX since I found it for a good price.

So 1000W (80A on 12V rails) should be plenty for my setup?


Any final suggestions (HX vs AX vs Others not mentined) before I pull the trigger?

I am also going to put my name in the hat for the Corsair, I just recently picked up an HX850w and I could not be happier with it. Nice packaging and looks to boot, along with a 7-warranty. From the reviews all around the net, Corsair is really doing a home run job on the HX series PSU's and I don't think you can go wrong or ever be disappointed in their quality/performance.

considering HS got the HX100w to 1500w and the the GTX 580 in 3way-SLI during full stress will pull around 930w in total system power, i would say you will have no power issues.

Mainboard

eVGA X58 Classified

Processor

Core i7 965 @ 3750 MHz (25x150 @ 1.35v)

Memory

Corsair Dominator 6144 MB (3x 2048 MB) DDR3 @ 1600 MHz CAS7 1T

Measured power consumption

With 3-way SLI we noticed our power consumption for the cards peaked to roughly 736 Watts. As stated, our test policy has changed, the very same test with three cards on FurMark would result in a 900+ Watt power draw.

1. System in IDLE = 272W
2. System Wattage with GPUs in FULL Stress = 933W
3. Difference (GPU load) = 661W
4. Add average IDLE wattage ~ 25W x3
5. Subjective obtained GPU power consumption = ~ 736 Watts

The Corsair is an excellent unit (I have one in my current system, and it's been going strong for over 2 years of abuse), but it is a somewhat older design at this point. It's not as efficient, and has more ripple than some newer designs on the market. There's absolutely nothing wrong with it, and I'd highly recommend one if you can get it for a good price, but I'd personally probably go for the AX1200 - not so much for the extra 200W (which aren't really needed), but instead for the lower ripple and higher efficiency.

choose either of those besides the antec quattro- those seem to have certain quality control issues (never tried one myslef though)
