The mainboard supports ATX power supply for the power system. Before inserting the
power supply connector, always make sure that all components are installed properly
to ensure that no damage will be caused.
ATX 24-Pin Power Connector: JPWR1
This connector allows you to connect an ATX 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. You may use the 20-pin ATX power supply as you like.
If you
’
d like to use the 20-pin ATX power supply, please plug your
power supply along with pin 1 & pin 13 (refer to the image at the
right hand). There is also a foolproof design on pin 11, 12, 23 & 24
to avoid wrong installation.
