Power Supply
The mainboard supports ATX power supply for the power system.
Before inserting the power supply connectors, always make sure that all com-
ponents are installed properly to ensure that no damage will be caused. 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.
ATX 20-Pin Power Connector
This connector allows you to connect to an ATX power supply. 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.
