best sli setup with on a 850psu

post #1 of 16
Thread Starter 
i still have 20 days left on my step-up and was hoping to make use of it. it will be for a 2d surround setup, 5040X1050. btw this is going in my sig rig. the 2 setups i'm looking at are:
2) 560 2gb
or
2) 570's
i'd like to go 580's if the psu will handle them, but i don't think it will.

Do you plan on overclocking the GPU's hardcore?
If so you would be skimming through with an 850 watt psu, if only a mild overclock then an 850 would suffice.
With a 570 you would prolly be able to get a pretty high overclock.
Look around and see what a 570 would have to overclock to, to reach 580 speeds.

580s would be a nice way to go but yeah, your PSU would be an advisable upgrade. You wouldnt want to overclock and if you could run them with an 850w psu, i reckon you would be pushing it a little.
For a multi monitor setup, the more vram the better, also i dont know if your just gaming but if your doing intensive 3D work then again, the more the better.

SLI 580 on a quality 850w power supply is perfectly fine and I myself will probably go that route sometime.

Your current psu will handle 2x gtx580,
but seasonic x850/corsair ax850 are better options,but if you upgrade your psu then I would say get the corsair hx1050(newly launched).
Hope you like my suggestion.

seasonic x850
corsair ax850

this is going to be a gaming rig. i'm working on a racing sim cockpit, hence the reason for wanting to make use of the 2d surround.

Any dual SLI will run on a quality 850W PSU, including two GTX480s.
post #10 of 16
You are going to need a PSU buff to comment on your psu but I have run SLI 580's OC'd to 900 on my Seasonic X 750, so depending on the quality of that PSU you are still within the range.
