PSU Question

[dondanielj]

Hey,

Currently Iam running a computer with 1 Graphics card, Sapphire Radeon HD 7970 (OC) and using the XFX Pro 550W Power Supply, and it's stable.

For Christmas, I got a second Sapphire Radeon HD 7950 (OC), and I do not want to use it right now, as I am not sure if my PSU will handle it, so I am looking to buy a power supply, that will easily handle the 7970 Crossfire.

I been looking only for a modular PSU, and found an "Corsair HX750 750W Modular PSU", But I am not sure if it will be able to run my system with 2 Graphics cards.

MB - Asus Crosshair IV Formula
CPU - Phenom ii x4 980 black edition (OC)
GPU - 2x Sapphire Radeon HD 7970 (OC)
HDD - 2TB
SSD - 120GB

What you guys think? Maybe theres any different PSU with similar price on the market?

Hi - do you have 2 7950's or 2 7970's?

Tom

2 7950's need 700w, 2 7970's need 800w, altho the xfx 750 should run them ok

My fault, 2 7970's..

My fault, 2 7970's..

Yes - the hx750 will run the 2 7970's.
