ATX 20-Pin Power Connector
To connect the ATX power supply, make sure the plugs of the power supply
are inserted in the proper orientation and the pins are correctly aligned. Then,
push down the power supply plug firmly into the connector.
The VIA EPIA-M Mini-ITX Mainboard requires an ATX power supply to be
connected. Before inserting the power supply connector, always make sure
that all components are installed correctly to ensure that no damage will be
caused.
