No. you can't add up. FSP has a total output of 680W on 3.3V, 5V, and all 4 12V rails combined. If absolutely no power is drawn from 3.3V and 5V., then 680/12 = 56.67 Amps is available for the 12V rail. If the load on 3.3V and 5V is 50% for each, then (680-3.3*18+5*15)/12 = 45.5A is available for the 12V rails.
For the Xclio, I am unable to find the total output on the 3.3V, 5V, 12V rails, or the multiple 12V rails. However it cannot be more than 750/12 = 62.5 Amps available for the 12V rail. If the load on 3.3V and 5V is 50% for each, then (750-3.3*15+5*14)/12 = 52.5A
EDIT: yes, I agree.. the FSP's are great. Of the two, I'd take the 700W for the X1900XTX's. If you go for PC P&C, then take the kilowatter; it's only a bit more money than the 850W version.
Final post for now..gotta go.. otherwise, gf kill me !
