ATX12V Power Connectors
The two power connectors let you attach two leads from an ATX12V power supply to the
motherboard. The ATX12V standard requires a 20-pin ATX connector plus a 4-pin ATX12V
connector. The two power connectors on this motherboard can accommodate either standard.
For an ATX12V power supply insert the 20-pin lead of the ATX12V into the first 20 holes of the
power connector leaving the last four empty, and the 4-pin ATX12V lead into the first 4 holes on
the secondary power connector, also leaving the last four holes empty. See the connector
diagrams below.

Note:
1. Use only ATX12V-compliant power supplies with the board. ATX12V power supplies have an additional
power lead that provides required supplemental power for the processor. Always connect the 20-pin and
4-pin leads of ATX12V power supply to the corresponding connectors, otherwise the board will not boot.
2. Do not use a standard ATX power supply. The board will not boot with a standard ATX power supply.
