Delock Fan Power Cable DC Jack 5.5 x 2.1 mm to 2 x 4-Pin Fan Connector (2 Pins Occupied) with Switch 1 m

Many PC builds require additional cooling fans, but motherboards often lack sufficient fan headers. This Delock cable solves that problem by converting a standard DC power jack (5.5 x 2.1 mm) into two 4-pin fan connectors, allowing you to power up to two fans directly from a power supply unit. The integrated ON/OFF switch gives you manual control over fan operation, and the 1-metre length provides flexibility in cable routing. The 4-pin connectors have only two pins occupied (power and ground), making them compatible with both 4-pin and 3-pin fans, though PWM speed control is not supported.

Who is it for

This cable is ideal for PC enthusiasts, system builders, and anyone who needs to add extra cooling fans to a computer case, server, or other 12V DC applications. It is especially useful when motherboard fan headers are limited or when you want to power fans independently of the motherboard.

Main features

• Converts a DC power jack (5.5 x 2.1 mm) to two 4-pin fan connectors
• Integrated ON/OFF switch for manual fan control
• 1-metre cable length for flexible installation
• Compatible with standard 12V PC fans (4-pin and 3-pin for power only)
• Durable PVC jacket and black colour for a clean look

Specifications

• Input connector: DC power jack, 5.5 x 2.1 mm, female

• Colour: Black

Tips

Ensure your power supply provides a stable 12V DC output and that the total current draw of the connected fans does not exceed the cable's capacity. Use the switch to turn off fans when not needed to reduce noise and save energy. For PWM speed control, connect fans directly to the motherboard instead.
