Power Connectors
Use a power supply that complies with the ATX12V Power Supply
Design Guide Version 1.1. An ATX12V power supply unit has a
standard 24-pin ATX main power connector that must be inserted
onto CN8.
Your power supply unit also comes with a 4-pin +12V power
connector. The +12V power enables the delivery of more +12VDC
current to the processor’s Voltage Regulator Module (VRM). Connect
the 4-pin power connector to CN9.
