Psu wattage help

[proton9]

my cheapo psu has 1 12v rail at 20A, - 12v at 0.8A, 3.3v at 25A, 5v at 25A and 5vsb at 2A what is its wattage then, is it near about 450?

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

theres nothing on the label except those ratings

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.
