1. Maker sure that all the connectors are connected to proper ATX power sup-
plies to ensure stable operation of the mainboard.
2. Power supply of 350 watts (and above) is highly recommended for system
stability.
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 sup-
ply 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.
ATX 12V Power Connector: JPW1
This 12V power connector JPW1 is used to provide power to the CPU.
