ATX 20-Pin Power Connector: CONN1
This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plug of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down the
power supply firmly into the connector. The power connector supports in-
stant power on function which means that system will boot up immediately
when the power supply connector is inserted on the board.

1. These two connectors connect to the ATX power supply and
have to work together to ensure stable operation of the
