The +3.3V and +5V total output shall not exceed 100watts, and the total output for
this subject power supply is 170 watts. Ripple and noise measurements shall be
made under all specified load conditions through a single pole low pass filter with
20MHz cutoff frequency. Outputs shall bypassed at the connector with a 0.1uF
ceramic disk capacitor and a 10uF electrolytic capacitor to simulate system loading.
