The below table provides the External Power Supply pins of the external power supply interfaces on
the DPU. For further details, please refer toExternal PCIe Power Supply Connector.
Pin Number Description
1 12V
2 12V
3 12V
The mechanical pinout of the 8-pin external +12V power connector is shown below. The
+12V connector is a GPU power PCIe standard connector. Care should be taken to ensure
the power is applied to the correct pins as some 8-pin ATX-type connectors can have
different pinouts.
