This connector is compatible with 2 x 10
connectors previously used on Intel Desktop boards.
The board supports the use of
ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables.
When
using a power supply with a 2 x 10 main power cable, attach that cable on the
rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24
unconnected.
•
ATX12V power
– a 2 x 2 connector.
This connector provides power directly to the
