How much power required for 780 SLI?

post #1 of 24
Thread Starter 
Would my Seasonic 860W Platinum be able to power a 3930K at 4.7GHz and two overclocked 780's under very high system load?

Thank you.

You could do it with a 650 watts PSU and still have power left over

So yes

Yes but the total power draw on a 4.7ghz 3930k is significant. Mine draws around 380w on full load @4.6ghz. Adding the 780s should bring it up to around 750w+ on load. Might be worth noting if the electricity bill is a concern.

what about a 3770K @ 4.6 plus SLI 780s OCd? i'm looking at getting a corsair AX860i. Do you think that is enough? 1000W+ seems like overkill.

AX760i would be plenty unless running stress tests all day with very heavy OCs.

Unless you're really just interested in the software, there are some better options than AXi though, especially if considering the price.

The Corsair AX i models are overpriced models with a silly gimmick that only works when it feels like it

The normal AX760/860 are Seasonic units the AX i models are Flextronics units

Really you would be better off with a Cooler Master V same PSU as the AX760/860 and the Seasonic X and Platinum just cheaper

If you want better then that then there is the Super Flower Leadex/EVGA SuperNova G2/P2 the NZXT HALE 90 V2 and the Antec High Current Pro Platinum
