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.

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 con-
nector and make sure it is secure.
