How powerful of a PSU would I need for 2x 570 SLI?

post #1 of 13
Thread Starter 
Would a 750W do it? I'll be doing a total rehaul of my PC over the summer and 570x2 SLI is looking to be a possibility.

A quality 750w should do the job, get a 850W to have more headroom for OC and future upgrades.

A good 750W will work but personally I'd go w/850-900W just to have some extra headroom, esp. since 850W units are usually not much more than 750W's.

I asked the same question about the PSU in my sig rig and 2 GTX 580 Lightnings over in the PSU section and they said it would be fine. I'm sure a good quality PSU would have no problems with 2 GTX 570's...

each 470 is gonna draw about 220w on load, by load i mean MAX load, add 150watts for cpu, ram, mobo and hdd's, add 50 watts for large amounts of fans, and or watercolling pumps
