ATX 12V Power Connector: JPWR1/ JPRW2
The 12V power connector (JPW R2) is used to provide power to the CPU. The
other one 12V power connector(JPW R1) is used to provide power to the installed PCI
Express graphics card.
ATX 24-Pin Power Connector: ATX1
This connector allows you to connect an ATX 24-pin power supply. To con-
nect 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.

MSI Reminds You...
1. These three connectors connect to the ATX power supply and have to
work together to ensure stable operation of the mainboard.
2. Power supply of 450 watts (and above) is highly recommended for
system stability.
3. ATX 12V power connection should be greater than 18A.
