Can a Seasonic X650 push an I7 and (2) 570's

post #1 of 37
Thread Starter 
Based on my current setup, could I run another GTX 570 safely? If I did would I be able to have any room for an OC on anything or should I step up to an X-850 to allow more wiggle room. Hindsight is kickin me for not gettin an 850 to begin with for peace mind.

No, you'll want to look at a 750w unit for that kinda load.

Without any overclocking; it might not even be enough.

That's what I'm afraid of. Don't wanna jack my whole system with low juice. Thank you much.

I think you will be around 675 -680w when loaded.

650w would work with two GTX 570's... as for overclocking I just wouldn't do any volt mods on the cards.

You wouldn't break anything.

You PSU would just shut down.

go for the X750/AX750 instead, i had it running 2x 570's at 1.1v and a 1090t at 1.5v just fine, was folding so 100% load 24/7

From a customer build, a Seasonic X650 will absolutely run 570sli for gaming.
Just don't run Furmark and CPU benches at the same time.

You're cutting it close, but your cutting it with arguably the best PSU on the planet regardless of wattage.

I think you're overestimating the power usage of GTX 570's a little. Unless he is folding 24/7 with the cards overvolted I can't see there being any problem. normal load conditions will show him mostly at 400-550WDC.

I would definitely usually recommend 750w for two GTX 570's for the extra wiggle room, if he didn't already have a 650w (which is the minimum, but just enough IMO).
