I ran 480 sli @ 800mhz and 2600k @ 4.7 on my hx750 no problems. Your chip is gonna draw more power but the ax750 mentioned above will be sufficient.

Ah, you're right. I originally saw only 2 pcie connections and 2 pcie cables, but there are at least 4 6 Pin cables there.

750w is enough, 850w is what you really want if you plan on pushing it, more if you intend folding or any other extreme use (like benching etc) with the setup.

Anything from Antec's TPN/TPQ or HCP range will be perfect, along with Silverstone's Strider+ or gold range. Other options include the Corsair HX/AX, Kingwin's Lazer gold/Platinum and Seasonic.

If you're feeling rich, consider the Lepa 1600, or the Enermax gold rated 1kw.

a good 750w PSU is more then enough. 850 would give you a nice buffer depending on how many other fans/ watercooling you may be running.

i have 2 480's OC to 850 core and a 2500k@ 4.5ghz along with 4 case fans and an SDD and the most i have ever gotten it to pull at the wall is 798 during benchmarking, which is ~680w out of the PSU on an 80+ bronze unit. dont listen to these people who run off and say "OMG you need a1kw PSU for those". they havent owned them and dont know what theyre talking about.

if you can cough up another $20 and are willing to buy it by tomorrow night the seasonic X750 gold is on sale for $119 at newegg.
