2.11 Installing the Power Supply
There are three power connectors on your S8230. It is required that you have an
EPS12V power supply which has one 24-pin and two 8-pin connectors.
24-pin (PW1)
8-pin (PW2, PW3)
NOTE:
Please be aware that ATX 2.x, ATX12V and ATXGES power
supplies may not be compatible with the board and can damage the
motherboard and/or CPU(s).
Applying power to the board:
Connect the EPS12V 8-pin power connectors. Both PW2 and PW3 are for
CPU loading. With light load processors, such as HE model, one 8-pin
connector is OK. With SE model processors, both 8-pin power connectors
are required.
Connect the EPS/12V 24-pin power connector.
Connect power cable to power supply and power outlet.
NOTE:
You must unplug the power supply before plugging the power
cables to motherboard connectors.
