Hey guys I'm going to be ordering some parts for a new build sometime in the near future. I was just wondering what size PSU I am going to need. Here are the components:

ASRock Extreme3 Gen3 Z68

Intel i5 2500k Sandy Bridge

Saphire Radeon HD 6970 (will be getting a second in the future for Xfire)

Mushkin 8GB DDR3 1600

Samsung Spinpoint F3 1TB

Corsair H100 liquid CPU cooler

Plus a Bluray optical drive, 4 fans, a few LED lights and I think that's about it. I was thinking about 850W would be enough, but since I plan on running 2 6970s in the future I'm not sure if it will be enough.
