Maximum combined wattage of 3.3V and 5.0V  outputs is 375W.

a. 

The efficiency of the power supply should be met over the AC input range defined
in Table 1, under the load conditions defined in Section 3.3, and under the
temperature and operating conditions defined in Section 5. The power supply should
be a typical of 72% efficient under full load as defined in the applicable
configuration.

b.

The +5Vsb standby supply efficiency should be 65% at 2.0A output. Standby
efficiency is measured with the main outputs off and with PWR_ON high. The AC
input power shall not exceed 8 W when the main outputs are in the "DC disabled"
state with 1.0 A load on +5VSB and the input is 230Vac/50 Hz or 115Vac/60Hz.

a.

The following output ripple/noise requirements should be met throughout the load
ranges specified in Section 3.3, and under all input voltage conditions as specified in
Section 3.1.

b. 

Ripple and noise are defined as periodic or random signals over a frequency band of
10 Hz to 20 MHz. Measurements shall be made with an oscilloscope with 20 MHz
bandwidth. Outputs should be bypassed at the connector with a 0.1 uF ceramic disk
capacitor and a 47 uF electrolytic capacitor to simulate system loading.
