Sli would be seriously pushing it, I would get a nice 850w especially because you have highly oc'ed cpu and water cooling.
Will you overclock the gpu's?

You will be fine with one 580, for 2 I would go 850 watt for sure.

if u go single graphics card i think you're fine. I would think you want more around 1000 for sli though just so you don't end up getting any performance choke on max draw.

No.

@OP You'll need atleast an 850w. I'd imagine it would *probably* work if you didn't run CPU/GPU stress tests simultaneously however it is still cutting it close for your PSU.

From Anandtech:
Looks like you're fine if you just plan to run games but if you're stress testing the cards you will be pushing your PSU (these are from the wall so the actual draw from the PSU is less once you factor in efficiency losses)
