This is fairly imprecise but how else are you going to know how much power you will need?
125W CPU + 130W GPU + 150W GPU = 405W.
I couldn't find any details about the TDP of 8800 GTS 512's, so based on the fact that they only have one 6-pin PCIe connector, the card uses between 75 and 150W, so I used 150W as a worst case.
As a worst case, 405W is not going to be stressful to a good 650W PSU. So I don't think you'll have any problems or need to change PSU.
 

Not bad.
149 watts running Furmark;

What Silvune said.

It is recommended to leave plenty of overhead room with your power for power spikes and upgrades down the line, but as of now a 650W PSU should easily handle what you have.
