750watt enough?

post #1 of 13
Thread Starter 
can my Corsair HX750W handle a second EVGA GTX 570 (SC)?
got 9hd's (3 of them are in RAID5), overclocked CPU @ 4Ghz,
watercooling, 6 fans (4x 120mm and 2x 140mm)
max TDP what a GTX570 can use is 225Watt

Yes, that's plenty enough PSU for your rig.

Is it also enough for a 2nd gpu?
post #4 of 13
Plenty and room to clock them a decent amount.
The only point where your PSU may be inadequate is if you run furmark/kombuster and LinX at the same time (AKA the OCCT PSU test), and how often will you do that?

Yes, it'll be enough even for a second GTX570. Even running Furmark + Prime.

HX750 will be plenty. that psu can push near 900w peak load before going out of spec. that setup, should be fine on the HX750

750 is the recommended power to handle 570's so you are at the right level for what you want

i just measured my pc
idle overclocked = 210Watt
with LinX@4GB and FurMark 1.9 = 605Watt
playing a game (TDU2 on Very High) = 300Watt-400Watt

so yeah, a second videocard for folding is coming near me and soon

did you apply the efficiency formula?
hx 750 is 88% efficient @ 50% load

so in fact you drawing 12% less from the pu then from the wall

605 watts @ 88% efficiency = 532 watts drawn from your psu
