Power Connectors
 ATX 24-Pin Power Connector: JPWR1
This connector allows you to connect an ATX 12V 24-pin power supply. To connect the
ATX 24-pin 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 12V Power Connector: JPWR2
This 12V power connector is used to provide power directly to the CPU voltage regulator
and must be used. Failure to do so will prevent the motherboard from booting.
NOTE:
 Make sure that all the connectors are connected to proper ATX power supplies to
ensure stable operation of the Motherboard
 ATX 12V power connection should be greater than 18A.
 If a high power (75W or greater) add-in card is installed in the PCI Express connector,
that card must be connected directly to the power supply. Failure to do so may cause
damage to the motherboard and the add-in card.
