Atx Power Supply Connector - Acorp 6A815EP User Manual

2-3-3 ATX Power Supply Connector

ATX power connector has 20 pins, which is especially designed for ATX case.
The ATX power supply supports the function of the "Soft Power On Momentary
Switch" which connects 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.
To support i815EP chipset, we suggest that Pin 17 signal 5VSB on ATX
Power supply should be able to offer at least 1A driving ability.
