24-Pin System Power Connector: JPWR2
This connector allows you to connect a 24-pin power supply. To
connect the 24-pin power supply, make sure the power supply
connector is inserted in the proper orientation and the pins are
aligned. Then push down the power supply firmly into the connector.
You may use the 20-pin power supply as well. If you ’d like to use the
20-pin power supply, please align your power supply connector
with pin 1 & pin 13. There is also a foolproof design on pin 11, 12, 23
& 24 to avoid wrong installation.
