GPU Aux Power Sockets in PowerEdge T550 Explained

In the Dell PowerEdge T550 server, the auxiliary power for a GPU comes from specific power connectors on the server’s motherboard and power supply unit. These connectors are designed to provide the additional power required by GPUs, especially high-performance ones, beyond what the PCIe slot itself can supply.

PowerEdge T550 GPU Auxiliary Power Connections

1. Dedicated GPU Power Cables:

• The Dell PowerEdge T550 has dedicated power cables coming from the power supply unit (PSU) to provide additional power to GPUs.
• These cables typically have connectors that match the common auxiliary power inputs on GPUs, such as 6-pin, 8-pin, or 6+2 pin PCIe power connectors.

2. Power Distribution Board (PDB):

• Some configurations of the PowerEdge T550 include a Power Distribution Board that manages power from the PSU to various components including GPUs.
• The PDB will have specific sockets for GPU power cables.

Specific Connectors for GPUs in PowerEdge T550

• 6-Pin PCIe Power Connector:
• Provides an additional 75 watts of power to the GPU.
• Often used for mid-range GPUs.
• 8-Pin PCIe Power Connector:
• Provides an additional 150 watts of power.
• Used for higher-end GPUs that require more power.
• 6+2 Pin PCIe Power Connector:
• This is a flexible connector that can function as either a 6-pin or an 8-pin power connector, depending on the GPU’s requirements.

Steps to Identify and Use GPU Power Connectors in a PowerEdge T550:

1. Access the PowerEdge T550’s Internal Components:

• Ensure the server is powered off and unplugged.
• Open the chassis to access the internal components.

2. Locate the Power Supply Unit (PSU):

• Identify the power cables coming from the PSU.
• Look for cables labeled for GPU or PCIe power.

3. Identify the Power Connectors:

• These cables will terminate in 6-pin, 8-pin, or 6+2 pin connectors.
• Ensure they match the GPU’s power requirements.

4. Connect the Power Cables to the GPU:

• Insert the appropriate power connector(s) into the GPU’s auxiliary power sockets.
• Secure any excess cables to avoid obstructing airflow or other components.

5. Check the Server Documentation:

• Refer to the Dell PowerEdge T550 documentation or service manual for detailed diagrams and instructions regarding GPU installation and power connections.

Additional Notes:

• Compatibility: Ensure the GPU is compatible with the PowerEdge T550 in terms of size, power requirements, and supported configurations.
• GPU Power Requirements: Check the GPU’s power specifications to determine how many and what type of auxiliary power connectors are needed.
• Power Supply Capacity: Verify that the PSU has sufficient capacity to support the additional power load of the GPU(s).
• Installation: When installing multiple GPUs, ensure each GPU has its dedicated power connectors from the PSU to avoid overloading a single power rail.

By following these guidelines, you can safely and effectively provide the necessary auxiliary power to GPUs in a Dell PowerEdge T550 server.

Conclusion

GPU Aux Power Sockets refer to the additional power connectors provided by the motherboard and power supply unit. In the above steps, there are full step-by-step processes to identify and use GPU power connectors in a PowerEdge T550. After following all of these steps, you can safely and securely supply the necessary auxiliary power to GPUs on a Dell PowerEdge T550 server, which is the right option to select the best GPU dedicated server.
