The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low 
signal that turns on the +5V, +3.3V, +12V and –12V power rails.  When this signal is not pulled 
low by the system, or left open, the outputs (except the +5VSB and V bias) turn off. This signal 
is pulled to a standby voltage by a pull-up resistor internal to the power supply.
 

The efficiency is specified at 50% and 20% loading conditions to help reduce system power 
consumption at typical system loading conditions.

 

The +5VSB output is always on (+5V Standby) when AC power is applied and power switch is 
turned on. 
The +5VSB line is capable of delivering at a maximum of 4A for PC board circuit to operate.

Accepts an open collector/drain input from the system.
