Hi,

CPU: 8320 (maybe OC to 4.5~)
GPU: Crossfire 290/x (will OC)
2 HDDs
6 fans

OC would be probably be moderate.

I'm looking at the XFX Pro 850w XXX Bronze or the Seasonic M12II 850W Bronze Modular.
Are these good enough for this setup?

Do you currently already have the 8320? I would imagine 850W would be enough, I recommend a modular PSU they reduce the clutter inside the case. I don't think you are going to be doing much, if any, over clocking because they pretty much come at a high clock and when the temps go up they throttle the speeds, with two your temps will be even higher so I see even more throttling than one GPU.

850W should be plenty. I would add Corsair HX850 to the list of choices as well.

But if you want to have some breathing room there are plenty of good choices in the 1000W range such as Seasonic X series 1050W.
Pretty much all of them are about $200.

Not yet, im gonna pick it up later with the psu though. Still waiting for non-ref 290s to come out. So using a 7970 Gaming at 2560x1440 btw.

$50 difference between the 8320 and the 8350 here. Read that both are same except for 8350 being a higher binned chip.

Why did you ask?

 


I just feel if your going to be dropping the money on two 290s or 290x you should go with an intel i5 build, or at the very least get the best AMD processor you can which is the 8350.
