Well, right now you are squarely in the 650W range, assuming a good quality power supply. It's that "or similar" following the HD7850 that makes me nervous though. Unless you are set on your graphics card, I'd suggest you up to 750W to cover a stronger graphics card, if necessary...plus room for future expansion.

I'd probably go with this:

But you can get by with 650W OK if you actually go with the HD 7850.

Typically, you want to make a final decision on a video card and THEN pick your power supply.

Unless you're using dual GPU's, you don't need more than about 500 watts.

Everyone says it is, but I have no personal experience with it. You really don't need 750 watts though.
