About how much power should i need for this build?

[ACG754]

Processor: Intel Core i5-3570K 3.4GHz Quad-Core Processor
Graphics Card: MSI GeForce GTX 660 (May SLI later on)
Motherboard: AsRock Z77 Extreme4
Hard Drive: Western Digital Blue 7200 RPM 750GB
Memory: G.SKILL Ripjaws X Series 16GB (4 x 4GB) @ 1600
Cooler: Cooler Master Hyper 212 Evo Plus
Case Fans: 5 120mm Fans
DVD Drive: LG CD/DVD Burner

Any suggestions? I'm thinking about going for an AZZA Dynamo 850 850W. Any help will be appreciated, thanks.

750 watts would do that build with 2 x 660. Corsair, Seasonic and Antec are the first names in PSU's I always think of.
