Just noticed the Seasonic x750 Gold is on sale ATM:
Newegg.com - SeaSonic X750 Gold 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply
At $120, you can't really beat it at the price. I have this one myself and its excellent.
I used to think modular wasn't really needed myself, but honestly once you have one you'll never want a standard unit again. this particular unit has lots of extra cables, many you'll probably not even need. You only need to use what you need, reducing clutter in the case which helps improve airflow. And, it will run most SLI setups. It can handle SLI 570 without any issues at all, and I would guess SLI 680s would be fine too. Its extremely efficient.
Keep in mind, not all 750Watters would be able to pull it off. But this is one thats capable. I beleieve the Corsair AX750 is another that can, but its also a rebadged x750. There are a few others as well.
Its also quiet, as the fan doesn't run very often. (Fanless design)
If you will NOT be getting one of the high end 750watt units, then you may need to go up to a 850W for a SLI build. It really depends on the quality of the unit.
