PSON #
The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +12 Vdc power rail.
When this signal is not pulled low by the system, or left open, the +12 Vdc output turns off. The Vsb output remains on. This signal is pulled
to a standby voltage by a pull-up resistor internal to the power supply. The power supply fan(s) shall operate at the lowest speed.
PSON Signal Characteristics

PSON# = Low
PSON# = Open
Logic level low (power supply ON)
Logic level high (power supply OFF)
Source current, Vpson = low
Power up delay: Tpson_on_delay
Accepts an open collector/drain input from the
system. Pulled-up to the 5.0 Vsb located in
power supply.
