Are you wanting to go for overkill or what you would really need?
If you don't want overkill, 750watts would be enough for the parts + overclocking to your heart's content. A good 750 watts would run an overclocked cpu + stock SLI GTX 580's which use quite a bit more power than those cards. Recommendation is difficult when money isn't mentioned. If money's no object and you just want the best in performance and reliability, I'd say go with corsair or seasonic and I've heard the NZXT Hale series are quite good too.

A good 750W would be enough, but get a 850W for some headroom.

Those cards use about 130w EACH less than a gtx580 and those can be heavily overclocked on a good 850w unit. That system is pulling 256w from the WALL (which means full system usage) at full load with one card, I'd go as far as to say a 750w is overkill as it is. If you want to save money and gain efficiency, I'd say 750w is the max if not lower.

650W if you don't want to unlock the cards, or 700/750 if you do intend to unlock them.. also, get the Sapphire Toxic edition cards

A quality 650w unit will be enough.

Here are a couple from the top of my head:

Antec New TP-650
Corsair TX650 V2
XFX Core/PRO 650w
XFX XXX Edition 650w

Yeah, 750W is well sufficient. As you can see, Guru3D's system peaked to 437 from the wall, running FurMark...

On an OC'ed i7 setup with CCFL's too. This one is a great PSU, especially for the price.

Thank you all for your help..

After reading i don't want to be hamstrung..

And when looking at the 850 and the 750 price is not that much of a difference..
I'm also going push and pull with the H100

So I am thinking i'll buy this.

You can OC that setup back to hell and forth and still be fine with a 750W PSU. Anyway, that one's an overkill, 850W design pushed to 1050.

You're better off with any of the other suggestions in this thread.
