GPU cable routing

Use this section to understand the cable routing for the GPU.

Important

If the label on the GPU power cable shows connector information different from the illustration and table in this section, follow the instructions here.

FromTo power distribution boardCable length
1 GPU 1 (PCIe slot 1)GPU 1 power connector320 mm
2 GPU 2 (PCIe slot 3)GPU 3 power connector320 mm
3 GPU 3 (PCIe slot 7)GPU 2 power connector660 mm
4 GPU 4 (PCIe slot 5)GPU 4 power connector660 mm
Note

  • Depending on the GPU model, the information provided in the label of the GPU power cable might not match the connectors on the power distribution board.

  • Make sure to follow the instructions in this table and illustration when connecting the GPU power cables:

    • For GPU 1 and GPU 2, use the shorter cables (320 mm).

    • For GPU 3 and GPU 4, use the longer cables (660 mm).

    • If the label on the GPU power cable shows connector information different from the illustration and table in this section, follow the instructions here.

Note

  • Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n

  • When routing the cables, ensure that all cables are routed appropriately through the cable guides and cable clips.
