Would 510W be enough? I was looking at this PSU http://www.<a style='text-decorati...</a>/Product/Product.asp?Item=N82E16817703001

Those is a nice rig you got there! With those 7800's and the FX55 + Raptors...your gonna need alot of power. That PSU youve picked out is top of the line. PC Power is one of the best brands out there. Im sure the PSU could handle that rig...but just not sure about the 7800s. I know PC power makes a 850W model but that is crazy expensive. I say you should be ok.
