ATX Power
ATX power connector has 20 pins, which is designed for ATX case especially.
The ATX power supply supports the function of the “Soft Power On
Momentary switch” which connects on the front panel switch to the 2-pin
SOFT-PWR on the system board. While the power switch on the back of
ATX power is turned on, the full power will not go into the system board until
the front panel switch is momentarily pressed. Push the switch again to turn off
the power to the system board.
