Power Connectors
Use a power supply that complies with the ATX12V Power Supply
Design Guide Version 1.1. An ATX12V power supply has a standard
24-pin ATX main power connector and a 4-pin +12V power
connector that must be inserted onto CN10 and CN9 connectors
respectively.
The 4-pin +12V power connector enables the delivery of more
+12VDC current to the processor’s Voltage Regulator Module
(VRM).
The HDD-type and FDD-type power connectors are additional
power connectors. If you are using two graphics cards, we
recommend that you plug power cables from your power supply
unit into the two 5V/12V power connectors. This will provide more
stability to the entire system. The system board will still work even if
the additional power connectors are not connected.
