2.4 Function & Installation Instructions
2.4.1 ATX Power Supply Connector (20-Pin)
This connector connects to an ATX power supply. The plug from ATX power
supply will only insert in one orientation because of the different hole sizes. Find
the proper orientation and push down firmly making sure that the pins are aligned.
The system power can be turned off through software control, like the shut down
in Windows 2000 / ME / 98 / 95 start menu. Power management must be enabled in
the system BIOS in order to activate this soft-off feature. Once the system BIOS
receives the power management command from the OS, it will switch the system
power off.
