Looking at the specs on newegg, the antec 380 and 430 show the exact same ratings on the 3.3, 5 and 12v rails. Is this a typo or am I missing something in the way they are rated?

380-
+3.3V@20A,+5V@20A,+12V1@17A,+12V2@17A,-12V@0.8A, +5VSB@2.5A

430-
+3.3V@20A,+5V@20A,+12V1@17A,+12V2@17A,-12V@0.8A, +5VSB@2.5A

Yep, they are even more confusing since it lists the 430 as having 1 LESS amps on one of the 12 rails than the 380.

The amperage ratings mean little to nothing. Thats just the rated amperage each rail is limited to. The important part in the combined output of the 12V rails.

The 430 offers 360W to the 12V rails giving it a total output of 30A

The 380 offers 324W to the 12V rails giving it a total output of 27A

That is where the key difference is. The 430 is supply more power to the 12V rail then the 380 is.
