HX850W enough to handle 580 SLI 3GB Classified?

post #1 of 4
Thread Starter 
I already posted this question in the Nvidia GPU section. Most of the guys said I'd be do well with the HX850W to handle 2x EVGA 580GTX Classified 3GB.

http://www.overclock.net/nvidia/1132...0-sli-3gb.html

But what do u PSU experts say? I want to be 100% sure and not end up buying a new PSU.

But keep in mind that the EVGA 580GTX Classified's are different then regular 580's. They demand 2x 8-Pins and 1x 6-Pin power connections. They also have slightly higher clocks then regular 580's so they probably demand more power.

I'm not planning on overclocking these cards BTW.

Specs:

Asus Rampage II Extreme
i7-920 @ 4.2Ghz 1.275v D0 (with Corsair H50)
Corsair Dominator 12GB Kit 8-8-8-24 (TR3X6G1600C8D)
EVGA 580GTX Classified 3GB SLI
ASUS Xonar Essence ST
Corsair HX850W

Corsair 800D Case (3x Corsair 140mm fans)
Enermax Vegas DUO UCTVD12A (4x 120mm LED fans)
Corsair Dominator Airflow Fan

2x WD Caviar Green 2TB
1x WD Caviar Black 1TB
1x Seagate 750GB

Looks like the consensus here is that a quality 850 is perfect for 2x 580's.

edit: Just saw what you said about the classifieds....is it really necessary to post again after a bunch of people already answered you? If you won't listen to the people who already told you it was good why listen to anyone else?
