atX power ConneCtors
ATX 24-pin connectors connect the ServerBoard to the ATX power supply. Find the proper
orientation of the connectors and push down firmly to make sure that the pins are aligned
(the connector will only insert properly when properly aligned). The 8-pin connector is a
dedicated power connector to supply power for the CPUs. For Wake on LAN support, the
5-volt Stand-by lead (+5VSB) from the ATX power supply must supply at least 2A.
IMPORTANT
It is recommended that you use an ATX Power Supply that complies with the Intel ATX 2.03
specification.
