Suitable for
Extending CPU power reach in server chassis
Optimizing cable management in high-density server builds
Connecting power supplies to motherboards in custom hardware configurations
Improving airflow by reducing cable obstruction
When it may not be suitable
This cable is not intended for use with non-standard power connectors or devices that do not utilize the 8-pin CPU power interface. It should not be used to bridge connections between incompatible power standards or to extend cables for components other than the CPU.
Key specifications
Connector A: 8-pin CPU male
Connector B: 8-pin CPU female
Cable length: 0.3 meters
Application: Internal server power extension
How to use
To use the Supermicro power extension cable, first ensure that the server is powered off and disconnected from any electrical source. Identify the existing 8-pin CPU power cable coming from the power supply unit. Connect the female end of the extension cable to the male connector of the power supply cable. Then, connect the male end of the extension cable to the 8-pin CPU power socket on the motherboard. Ensure that both connections are fully seated and locked into place before restoring power to the system.
What to consider before purchase
Verify that your motherboard and power supply unit both utilize the standard 8-pin CPU power configuration.
Measure the required distance within your chassis to ensure 0.3 meters is sufficient for your specific layout.
Check for physical clearance around the CPU power socket to ensure the connector housing fits properly.
Usage recommendations
Always ensure that the cable is routed away from sharp edges and moving parts, such as cooling fans, to prevent damage to the insulation and ensure long-term reliability.
