The output is what you want to look at:
Mainly the +3.3, +5, and +12v rails.
so you're lookin at:
+3.3v - 17a
+5v - 24a
+12v - 28a
The +3.3v Rail is fairly weak, generally you want one in atleast the 20's, the +12v rail on the otherhand is pretty damn sturdy for the +12v rail which a lot of power will be coming from, CPU gets it's power directly from the +12v line, and so do all your fans, a little bit from each HD, and optical drives also.
Check out this page:
Gives you info on how to find out how much power you need. If you look at that chart not too many devices use the +3.3v rail so that rating of 17a will more than likely be enough unless you just really have a lot of stuff inside, you never want to use up the full 17a though, you want your total to be at like 13-14 after you've found out how much ampere's are needed on the +3.3v rail for your system.
EDIT: BTW leonidas, I can't believe that 5200 requires an extra molex connector, must be because it's the Ultra, I think all the Ultas in the FX series needs one, cause my 5700 doesn't need one but my friends 128mb 5700 Ultra does.
