Delay from AC being applied to +5VSB being within regulation

Delay from AC being applied to all output voltages being
within regulation.

Delay from PSON# active to output voltage within regulation
limits.

Delay from output voltage within regulation limits to PWOK
asserted at turn on.

Delay from PWOK deasserted to output voltages (+5V, +3.3V,
+12V, -12V) dropping out of regulation limits.

Duration of PWOK being in the deasserted state during an
off/on cycle using AC or the PSON# signal. .

Time all output voltage stay within regulation after loss of AC

Delay from loss of AC deassertion of PWOK.

Delay from PSON# deactive to PWOK being deasserted.

Delay from +5VSB being in regulation to O/Ps being in
regulation at AC turn on.
