The ground of the pins of the output connector provides the power return path. The ground pin
is connected to safety ground (power supply enclosure).
5.2.5.2 Output Power / Currents
The following table defines the current ratings for the 830W power supply.

Total continuous power = 830W
Total Peak power (note 2) = 882W
Notes:
Maximum continuous total DC output power should not exceed 830 Watts.
Peak power and peak current loading shall be supported for a minimum of 12 seconds.
5.2.5.3 Standby Outputs
The 5VSB output shall be present when an AC input greater than the power supply turn on
voltage is applied.
5.2.5.4 Stand By Operation
Fan-less operation requirement is the power supply’s ability to work indefinitely in stand-by
mode: with power on, power supply off and the 5VSB at full load (=2A) under environmental
conditions (temperature, humidity, altitude).
