If you buy a decent quality power supply from a known brand then you are good to run your rig off that wattage. However, I have seen power supplies in this range of wattage that don't come with the best spread of connectors. You might have to find some adapters.

[the_devil52]

Yeah 620W should be fine as long as it isn't some crap generic brand. Your setup probably won't even use all 620W.

620W will work, however will limit the upgradability of your computer.

What if 660W Gold, will it run on sli gtx 660 ti?

I'd say a Seasonic,Corsair,XFX or other high quality make power supply with 620+ watts would be able to handle your setup easily.

as to sli 660 ti's.

660 ti max power consumption -150w

660 ti 2 - 150w

3770K - 77 watts

everything else lets say 50w

total- 427w

xbitlabs.com also tested 660 ti sli and on their uber rig: 3960X @ 4.6ghz,2 HDD's and an SSD,6 fans,and a zalman control panel add on it took 540 watts.so you'd definitely be fine.

Yes, 500W is the minimum .

Hmm i am sorry i cannot help you there, however in my opinion it should work but it depends on the other specs of your system and if your over clocking the cards and CPU
