Internal power cable Supermicro CBL-PWEX-1171-2654, 0.54 m, internal PSU connectors

Supermicro CBL-PWEX-1171-2654 is a 0.54 m internal power cable intended for use inside servers and workstations. Supplied as a single unit, the cable provides short-range internal wiring between a power supply unit and motherboard or peripheral power inputs. The design supports compact builds and repair scenarios where a reliable, standardized internal power connection is required.

Advantages

The cable offers a compact 0.54 m length suitable for tightly packed chassis, reducing excess slack and improving airflow. It is made to match common internal PSU and motherboard connector layouts, providing straightforward installation without modification. As a single-unit component, it is convenient for targeted replacements or upgrades in server and workstation environments.

Suitable for

• Short internal PSU-to-motherboard power routing in servers and workstations
• Replacing worn or damaged internal power leads in compact chassis
• System repairs where a precise, short cable run is required to avoid cable congestion
• Builds that require standardized internal power connectors and tidy cable management

When it may not be suitable

This cable may not be suitable for systems that require longer cable runs than 0.54 m or for external power connections. It is intended for specific internal connector types; if your power supply or motherboard uses non-standard or proprietary connectors, confirm compatibility before purchase.

Key specifications

• Cable length: 0.54 m
• Connector configuration: internal PSU-to-motherboard/peripheral power connectors (standard internal types)
• Quantity supplied: 1 unit
• Primary use: internal power distribution for servers and workstations
• Form factor: short-run internal cable for compact chassis

How to use

Identify the matching internal power connectors on both the power supply unit and the motherboard or peripheral device. With the system powered off and unplugged, align the connector housings and gently press the plugs into place until they click or seat fully. Route the cable to minimize contact with fans and moving parts and secure it with existing cable ties or clamps. After installation, verify power delivery by powering on the system and checking that connected components receive power normally.

What to consider before purchase

• Ensure the connector types on your PSU and motherboard match the cable’s plug configuration
• Confirm that a 0.54 m length is sufficient for your chassis layout and cable routing needs
• Check system power requirements and connector pinouts to avoid mismatches

Usage recommendations

Use this cable for interior installations where minimal cable length improves airflow and reduces clutter. Avoid excessive bending at connector joints and secure the cable to prevent strain on connectors during transport or maintenance.
