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).
