RGB splitter cable Alphacool 18689 Black 300 mm

RGB splitter cable Alphacool 18689 Black 300 mm is a sleeved distribution cable that converts a single 3-pin connector into two 3-pin fan/RGB connectors. The cable transmits power and RPM/signal to multiple fan or RGB headers and features protective sleeving for improved durability and cable stability. With a 300 mm length and black finish, it is suitable for internal PC cable routing and neat installations.

Advantages

The sleeved design increases mechanical protection and reduces wear, while the Y-splitter layout lets one header feed two devices without additional adapters. Constructed with standard 3-pin connectors and matching pinout, the cable supports simultaneous power and RPM/signal distribution and maintains a compact, unobtrusive appearance in black.

Suitable for

• Connecting two 3-pin fans to a single 3-pin fan header
• Splitting power and RPM/signal from one header to multiple RGB/fan devices
• Internal PC builds requiring tidy cable management and short cable runs

How to use

Connect the single 3-pin plug to the motherboard or controller fan/RGB header, then attach the two 3-pin sockets to the target fans or RGB devices.

Route the sleeved cable to avoid interference with moving parts and keep within the 300 mm length for reliable connections.

Usage recommendations

Use this splitter for short internal connections only and avoid exceeding the current limits of the source header. For high-power devices, check the header's maximum current specification or use a powered hub to prevent overloading.
