EPS12V POWER CONNECTORS

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.

EPS12V PSU Only

IMPORTANT

It is recommended that you use an ATX Power Supply that complies with the Intel ATX 2.03 specification.
