gitangtang naman na ang 20A limit tingali sa bag-o revision na psu....not sure...

I think the official limit was 18A as mandated by EU Standards. But that is gone now. My PSU is going to be 5years soon. During that time the 12v limit was implemented but most power supplies just labeled their psu rails as 18A (up to 20A) just to comply with the rule though actually, each rail was capable of delivering 22A-25A. Mine was labeled 18A but the OCP per rail was 25A hot.

(EDIT: The official limit was 240VA diay, not 18A. It was manufacturers discretion to allot a 2A headroom.)
