Supermicro CBL-PWEX-0545 Internal Power Cable 0.17 m

The Supermicro CBL-PWEX-0545 internal power cable is a short 0.17 m cable built for firm, internal power connections in server and workstation environments. It uses a straight SATA 15-pin power connector designed to supply power to drives and other compatible components. The compact length reduces cable clutter and supports tidy routing inside chassis while maintaining a stable electrical connection between the power supply and peripheral devices.

Advantages

This internal power cable offers a compact form factor that helps manage airflow and cable organization inside tight chassis. The straight SATA 15-pin connector ensures broad compatibility with standard SATA power sockets on drives and adapters. Manufactured to Supermicro quality standards, the cable delivers reliable contact and reduces the risk of accidental disconnection during installation or service.

Suitable for (tasks / use cases)

• Connecting internal SATA drives (HDD/SSD) to power sources inside servers and desktops
• Powering SATA-based optical drives or adapter modules in compact chassis
• Cable management in rack-mounted servers and small-form-factor workstations
• Replacing short, damaged, or missing internal SATA power leads

Key specifications

• Connector type: Straight SATA 15-pin power connector
• Cable length: 0.17 m (approx. 17 cm)
• Application: Internal power distribution for SATA-compatible devices
• Compatibility: Standard SATA power interfaces used in servers, desktops, and storage enclosures

How to use

Route the cable inside the chassis from the power supply or power distribution board to the target SATA device and firmly seat the 15-pin SATA power connector onto the device’s power inlet. Ensure the connector is aligned correctly before applying pressure to avoid bending pins. Keep the cable clear of cooling fans and sharp edges and secure it with existing tie points or cable ties to prevent strain on the connection during operation or maintenance.

Recommendations

Use this short internal cable when a close, direct connection is available to minimize excess length and improve airflow. Verify SATA connector orientation and ensure a snug fit; replace the cable if insulation is damaged or contacts show corrosion. For best results in server environments, route cables to avoid obstructing airflow and label connections where multiple similar leads are present.
