It should tell you on the label where you got the rest of the info.
No way anyone could tell from those numbers.

I'm going to take a guess and say that you looked into the math on the 2nd page, if so use it on these numbers

+12v = 18a
+5v = 22a
+3.3v = 13a
+5vsb = 2a
-12v = .3a

+5v and +3.3v = 140 watts

I'll come back to see what that adds up to.
