Cable de extensión de conector de alimentación Supermicro 12V de 4 pines a 4 pines 20cm sin Pb

The Supermicro 12V Power Connector Extension Cable 4-pin to 4-pin 20cm Pb-free is a short extension cable designed to extend 12V four-pin power connections inside computer systems and server chassis. At 20 cm length, the cable provides additional reach for power routing in compact or crowded builds while maintaining stable voltage delivery for fans, pumps or peripheral modules that use a standard 4-pin 12V connector. The construction is lead-free, meeting environmental handling expectations for internal cabling.

Advantages

This extension cable offers a simple and reliable way to extend an existing 4-pin 12V power connection without altering the power path. The 20 cm length balances manageability and reach, reducing strain on connectors and enabling neater cable routing. Pb-free materials reduce lead contamination risk and align with environmental standards. The straightforward 4-pin to 4-pin design ensures compatibility with standard 12V devices and avoids additional voltage conversion.

Suitable for

• Extending 4-pin 12V fan connections inside PC cases
• Routing power to pumps or cooling equipment in small server racks
• Providing additional reach for peripheral modules and add-in devices that use 4-pin 12V plugs
• Temporary or permanent cable length adjustments during system assembly or maintenance

Key specifications

• Cable length: 20 cm
• Connector type: 4-pin to 4-pin 12V power connector
• Voltage: 12V nominal power line
• Material: Pb-free conductor and insulation materials
• Intended use: Internal power extension for computer and server components

How to use

Disconnect power to the system before installing the extension cable. Plug the female end of the extension into the existing 4-pin power plug coming from the power supply or power distribution board, then connect the male end to the device requiring the extended reach (for example a fan or pump). Ensure the connectors are fully seated and that the cable is routed to avoid sharp bends, hot surfaces, and moving components. Restore power only after verifying secure connections and correct orientation of the 4-pin plug.

Recommendations

Use the cable only for 12V DC four-pin power connections and avoid exposing it to liquids, excessive heat, or mechanical strain. For high-current applications, verify that the combined current draw of connected devices does not exceed the design limits of the source connector and wiring. Regularly inspect the connector ends for corrosion or damage and replace the cable if any degradation is found.
