Doing the unthinkable.. GTX580 SLI on 650 watt PS.

post #1 of 20
Thread Starter 
So I have googled this and apparantly nobody has been dumb enough to try until now. I have one GTX 580 already and have ordered another. I am going to attempt to run them on a Seasonic X-650. Current system never breaks 375 watts under gaming load and even when it hits that is only for peaks. If it doesn't work I'll just get a new power supply. Predictions?

It depends on the overclocking and load you put on it.

Here is i7-980x and SLI GTX 480 on a TruePower New 550W:


Note that it's an Antec demo, but the setup is what it is. Power draw going to like 688W is AC I think, still over 550W DC. Obviously that's not quite a full load test.

No overclocking will be performed on the cards. They will be left at stock, with my CPU being fed 1.35v.

Yeah, it's an X-650. It'll just shut itself off if the load is too high, which shouldn't happen under your intended usage scenario. If just gaming and no overclocks on the GTX 580s, go ahead!

GTX480 and GTX580 are within 11 watts under heavy load and I run a GTX480 with an HX520. I think you'll be able to pull it off.

I also ran this one GTX 580 with a Corsair HX520 for a number of months in Q6600 build @ 3.6. No issues there. You are the first ive heard doing this besides me! lol

You will be fine. Anything lower than 650W though and I would say no.

I ran a 4870x2 on a 500W PSU!
