Higher rated power supply wasted?

[northman11]

I'm in the infancy stage of building a new gaming pc and I have a chance to pick up a SeaSonic Platinum SS-860XP2 860W for $100 which is a pretty good deal. I don't plan on overclocking and I will probably just run one GPU. Is this power supply overkill?

Yea it's definitely overkill. i'd rather get a 500w 80+ PSU for $50

If you ever do SLI/Crossfire it will come in very handy. If you can't see yourself ever doing that, you're just wasting electricity - a 850W PSU at idle (which is the state the PC is in a most of the time, unless you're a pro gamer or doing folding/rendering etc) definitely consumes more electricity than a 500W PSU at idle (idle draw is typically well under 100W). Normally I recommend getting the smallest PSU possible that is capable of driving the PC under 100% load. 400-550W is usually where you end up for average usage scenarios.

Without knowing the system specs I can't tell you if its overkill or not. If you are running a FX 9590 and a 390x then its not overkill. Overkill is not necessarily a bad thing. Over provisioning on a PSU with a hybrid fan will make it silent when idle and make very little to no noise when under load.

Thanks for the advice. I'll pass on the PS then and get one rated for the components I end up getting.

Or a 295X2.

With a fx 9590 and a 295x2, 860w would be borderline insufficient(i'd suggest atleast 1000w unit for that setup). But atleast the room it was in would be nice and toasty
