ATX 20+4-Pin Power Connector: ATX1
This connector allows you to connect to an ATX power supply. To con-
nect 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 instant
power on function which means that system will boot up immediately when the
power supply connector is inserted on the board.
This barebone provides you an additional 4-pin power supply cable for
connecting to the 24-pin power connector.
