Power Supply
This motherboard uses an ATX power supply. In order to avoid damaging any
devices, make sure that they have been installed properly prior to connecting
the power supply.
4-pin ATX_12 V Power Connector: PWR2
The ATX power supply connects to PWR2 and
provides power to the CPU.
24-pin ATX power connector: PWR1
PWR1 is the ATX power supply connector. Make
sure that the power supply cable and pins are
properly aligned with the connector on the
motherboard. Firmly plug the power supply cable
into the connector and make sure it is secure.
Note: We strongly recommend that you use 24-
pin power supply. If you want to use 20-pin power
supply, you need to align the ATX power connec-
tor according to the right picture.
