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 CN9.
Your power supply unit may come with an 8-pin or 4-pin +12V
power connector. The +12V power enables the delivery of more
+12VDC current to the processor’s Voltage Regulator Module
(VRM). If available, it is preferable to use the 8-pin power; otherwise
connect a 4-pin power connector to CN10 as shown below.
