Peak current determines the voltage under load, it's RMS current rather than
mean or 'average' that determines the heating effect in the transformer. If I
remember correctly, transformer RMS current is typically 2-3 x dc current in
a bridge/capacitor input psu. The psu designer prog. gives you good
information about what's going on and has accurately diagnosed shortcomings
in several psus I've looked at.
