Interesting, but not quite clear!

The output voltages are,
+12v at max 15 amp, i.e, 180w
+5v at max 20amps, i.e, 100w
+ 3.3v at max 16 amp, i.e, 53w
-5 v at max 0.5amp, ???
-12 v at max 0.3 amps ???

12v ×14 amp = 168 watt x 2 outputs= 336 watt ( see 3rd pic)
5× 20 amp = 100 watt
3.3v ×  16 amp = 52.8 watt
-5 v × - 0.5 amp = 2.5 watt
-12 v × - 0.3 amp = 3.6 watt

Total 494.9 watt

12V rail has two outputs?
You mean you have put two SMPS components in one box?
BTW can you post ratings of SMPS itself.

So if you join both the yellow you can load 28 amps .... ?
