PSU - Good enough for SLI?

post #1 of 4
Thread Starter 
I have an XFX Black Edition 850w Power supply, and it's been running great so far.

I'm thinking of running another GTX580 in SLI with the one I already have, and I'm unsure if my PSU will handle it. I used the PSU calculator to see if my psu would allow it and its total usage goes up to 775w, but while folding it goes to 930w.

If I don't fold 24/7, and only occasionally, does my PSU have enough capacity to support that (check my sig rig for other components.)

Yeah, it's enough.

850 will run 580 SLI with a good OC. Remember that your watt readings from the wall will be much higher since even an 80+ gold runs at 80% efficiency.

930 * .8 = 744
