Thanks again for your help guys. So what I'm hearing from you guys is that for my system a 600watt power supply would be best and anything more would be wasting electricity.

One thing I was thinking I might do down the line was buy another clone of my graphics card and hook them up in SLI, that is why I initially chose a bigger power supply. Therefore, another question I have is whether the PSU uses the wattage that is assigned to it 700W 650W or does it just use what it needs? Also how inefficient is a PSU when it is only sourcing components under the rated wattage?

In relation to those questions, would it be better to buy a bigger power supply now to be ready for SLI or start with a smaller one and buy a new one if I plan to upgrade to SLI?
