Alphacool 18677 RGB Splitter Cable Plastic Black 300 mm

The Alphacool 18677 RGB splitter cable is a 300 mm sleeved distribution cable that converts one 4-pin connector into two 4-pin connectors to power and synchronize multiple PWM-capable RGB fans or devices. Constructed with plastic housings and protective sleeving, it delivers stable power and PWM signal distribution while minimizing cable wear.

Advantages

The sleeved design adds mechanical protection and improves durability. The compact 300 mm length keeps cable runs tidy inside a PC chassis. The Y-splitter format allows a single header to feed two devices, simplifying installation and reducing the number of required motherboard or controller ports.

Suitable for

• Connecting two 4-pin RGB/PWM fans to a single 4-pin header
• Expanding RGB lighting by linking compatible RGB devices
• Systems with limited motherboard or controller headers

Key specifications

• Brand: Alphacool
• Model / MPN: 18677
• EAN: 4250197186773
• Connector: 1x 4-pin to 2x 4-pin (Y-splitter)
• Length: 300 mm
• Material: plastic connectors with protective sleeving

How to use

Connect the single 4-pin end of the splitter to an available 4-pin motherboard or controller header that supplies power and PWM signal. Attach the two 4-pin ends to the fans or RGB devices you wish to power and control. Verify that the combined current draw of connected devices does not exceed the header or controller specifications. Route the sleeved cable to avoid interference with other components and secure it as needed.

Recommendations

Use this splitter only with compatible 4-pin RGB/PWM devices and ensure the power and PWM current limits of the motherboard or controller are respected. For best results, connect identical devices to maintain synchronized lighting and fan control.
