Total maximum power is what is allowed for the whole supply based on its
ability to dissipate waste heat
and the capability of the initial circuitry to handle the incoming power
before its divided into each DC output.
You can't run all the output lines at their maximum powers, the manufacturer
just gives you the max rating of
each so you can run some of them up to max, assuming the others have low
enough loads so the total meets
overall power rating.

Phase angle only comes in on the AC side, probably not involved in the
ratings you describe. If you see a
VARS rating (for Volts x Amperes Reactive) this would be related to Max
parameters of incoming power
from the AC line.
