i think its overkill. For the same price range, you can get the Ax860i.

Overkill, an AX850/860 is more than adequate for that setup. If you keep your CPU at less than 4.6GHz(ish) even the AX750/760 is enough, I say that because the SB-E chips really can draw a lot of power.

I would recommend a XFX 850 unless you ONLY want a corsair. I have the seasonic X1050 and love the hybrid fan mode which is something the AX 860i offers too (fan does not come on till needded).

Newegg has a 20% off on XFX PSUs going on right now - http://www.newegg.com/Product/Product.aspx?Item=N82E16817207011

Overkill, like others have said, but it can't hurt having that much power either biggrin.gif.

It is overkill for this build, if you plan on upgrading in the future with some UBER amount of UBER GPUs and overclock then all this power will come in handy. If not then go with a 850 max.

Yes, gonna be OC CPU to hopefully 4.8 - 5.0 Ghz and will also be OC the 2 MSI 7970. I know the i7 3930k and (2) 7970 are going to be power hungry especially when OC.

Inquiring about the Corsair HX1050 because traded it for 60gb XBox 360.

The AX860 is a better PSU than the HX1050 and can actually supply a higher wattage (sounds crazy I know) so I'd go with that if you want to be safe.
The 3930K really is very power hungry.

I wouldn't call it "overkill", but rather some additional headroom. Keep in mind, several people are running duel power supplies, not just single, to have better efficiency. The more you go past the "80+" rating, the more falloff you may have. Therefore, loading a PSU up to 80% is common more so now so the efficiency yield is closer to specs.

It is overkill and it's not a great unit. If you have it already then stick with it, if not, don't buy it, you can do better.
