What is the outpout of this power supply?

[RampRat]

This is a no name power supply and I would like to know the W power (250, 300 ...) of it. Help me please. I would like to know if I got what I paid for. Thanks.
Here is what is on the sticker.
+3,3v:15a
+5v:22a
+12v:11a
-5v:0,5a
-12v:0,5a
+5vsb:1,5a
115-230v
cvr 6/3a
max freq 50-60Hz

This one can be called as a full power 250W...or a generic "unfull" 300W PS
Base on my understanding!

 

[V]

That is a 300w power supply.

+3,3v:14a
+5v:30a
+12v:8a
-5v:0,5a
-12v:0,5a
+5vsb: PUR
115/230v 6A53A 60/50HZ

What about this one?

Just gotta do the math:

(amps x 3.3 volts) + (amps x 5 volts) + (etc for each voltage) = total watts.

For Ramprat's model, that's 307.5 total, unless I screwed up...
