I'm inclined to say that PCPartPicker is inflating the estimate a bit. But, it's your build. Between the 3 you listed, I'd say either the NZXT or the EVGA would be fine.

Edit: Also, if you're talking about the HCG-750, according to Hardware Secrets, they were able to pull almost 1000w from it.

thats the one I have. is there a way for me to test the wattage on it? Without buying a second card and possibly frying everything if something goes wrong?


That's the same PSU. Not sure of how to test it. Anyway, I honestly don't believe you'll draw more than 750w with 2x280x, anyway.

ill give it a shot, but if my 8350 and my cards fry, I will find your house and poop on your lawn. And maybe your car too :)

You'll be fine. All the reviews I've seen seem to place the 280x at a maximum of ~250w. So even with 2 cards and power consumption scaling at 100% (which it doesn't), that'd still be only 500w. The 8350 has a TDP of 125w, so unless you up'd your voltage a lot for your OC, I don't believe you'd be pulling 200w for just that. Still, even then, that still puts you at only 700w.

Anyway, LOL @ the poop. However, if you are decidingly so set on trifire, you could just get a good 1200w PSU now.

the poop part was a joke, but if I do go 3 way crossfire, then I would upgrade it then. I let the oc software on my mobo do the actual oc'ing, so I dont thing it raised the voltage all that much.

I know. For some reason, I found it pretty funny.

Edit: Particularly the "and maybe your car too" part.

Edit2: And yes, upgrade PSU if you go 3 cards. 1000w to 1200w would work more than adequately.
