GTX 580 SLI on AX850

post #1 of 6
Thread Starter 
I already have one GTX 580 3gb running on my power supply and I'd like to know if I could run another 580 off it without killing it

Yes thats fine

The only reason I don't have SLI on mine is because watercooling has caused un-repairable damage to my bank account.

Easily, actually.

Guru3D.com got their test system to pull 719W from the wall outlet when it had two GTX 580s in SLI under full load (source). This means that the system pulled approximately 625-640W from the power supply.

Yes, you're fine, the AX850 is a super unit. I have 2 480's on it, and they are even worse than 580's
