GTX 580 Sli with a Corsair HX750?

post #1 of 6
Thread Starter 
I recently snagged a HX750 for $100 bucks. my goal was to run a GTX 580 and GTX 460 but I received an offer for the 460. I'm thinking about selling it and trying to find a used GTX 580 for cheap. do you guys think a corsair HX750 will handle two?

HX750 would definitely be recommended for SLI 580's and would certainly take the cake Check out Phaedrus Quick'n'Dirty PSU Calculator, right on the spot!

It would be pushing it, but you could do it. You're probably going to get a lot of responses that you can't, but as long as you don't plan to run prime95 and furmark at the same time you will be perfectly fine.

Yes it should... I wouldn't recommend overclocking the GPU's though... that used to be my previous setup...

It's going to be close.

The HX750 is a great PSU for sure but your power consumption could be pretty high in those first few moments before the current limiter kicks in. Assuming the HX750 can handle the initial spike while the 580s "cool themselves down", you should be fine since the "regular" draw is 390 watts leaving you plenty of room to power CPU, mobo, fans, etc. I personally would be a little afraid but the corsair is silver certified and is a solid PSU so you will probably be ok. Questionable but I think you will be alright. Good luck!
