Power On Connector
This header can be connected to a front panel power switch. Because of debounce circuitry
on the system board, the switch must pull the SW_ON# pin to ground for at least 50 ms to
signal the power supply to switch on or off. At least two seconds must pass before the
power supply will recognize another on/off signal.
CAUTION:
If you need to turn off the
computer during POST, hold the power switch in
for four seconds; otherwise the computer will not
switch off.
