I have selected my components, but am unsure how much power my system needs. I heard that it is very important to get a quality PSU as a cheaper one may damage your system. I plan to Crossfire my 6950s, and overclock my CPU and GPU to within safety temperatures. After doing some research on other builds similar to mine, I noticed that most people got PSUs around the 850w to 950w range. I wasn't sure if they also considered overclocking. In the future, I will also add on an additional one or two more 7200RPM hard drive.

You're going to need at least 40A on the 12V rail just of the cards, especially when overclocked. Id say atlease another 300W (25A) for the rest, id say the 850W is fine unless you plan on watercooling.
