It would be terrific if you could make a matrix with power supplies across the top of the page, and the critical results down the side of the page, like, for each voltage rail, and at 115V input and 220V input, I'd like to see (using the 12V rail as an example):
% voltage change on 12V rail from a 35W load to a 250 Watt load
% voltage change on 12V rail from a 250 Watt load to full power load
% voltage change on 12V rail from a 105V to 125V input voltage change with a 250W load
ripple voltage and frequency on 12V rail at 35 Watts
ripple voltage and frequency on 12V rail at 250 Watts
ripple voltage and frequency on 12V rail at full power
Input-Side transient response -- Hold up time (in ms or number of missing input-power cycles to cause a 10% dip in the output voltage), overshoot and settling time (i.e. given a 10% undershoot/dip) - in other words, if there is a power glitch that lasts 3 cycles at 60Hz (50ms) causes a 10% dip, what else happens to the output voltage?
Load transient response (i.e. peak overshoot/undershoot from nominal and settling time) on 12V rail from a 35 Watt to 250 Watt load step (up)
Load transient response on 12V rail from a 250 Watt to 35 Watt load step (down)
Load transient response on a 250 Watt to no-load step
Load transient response on 12V rail at turn on
Efficiency at full power load
Efficiency at 35 Watts
Temperature of worst-case exponsed component at full load after full warm up
Temperature of worst-case (or some representative) internal component at full load after full warm up
Power Factor
dB(A) audible noise level at full load
