RGB-splitterkabel Alphacool 18678 sort 600 mm

The Alphacool 18678 RGB splitter cable is a 600 mm sleeved distribution cable that converts a single 4-pin connector into two 4-pin outputs, allowing you to power and control multiple RGB devices from one header. Constructed with sleeving for improved protection and stability, this cable is intended for linking RGB fans or other 4-pin RGB components in PC builds.

Advantages

The sleeved design increases durability and reduces wear on the cable, while the dual 4-pin outputs enable simultaneous power and PWM/ARGB signal distribution to two devices. The 600 mm length offers flexibility for routing inside most PC cases, and the black finish provides a discreet appearance that blends with system interiors.

Suitable for

• Connecting two 4-pin RGB fans to a single motherboard or controller header
• Extending or routing RGB power and PWM/ARGB signals in desktop PC builds
• Linking multiple RGB components when header count is limited

How to use

Connect the single 4-pin plug to the motherboard or RGB controller header, then attach the two 4-pin outputs to the RGB devices (fans, LED strips or other compatible components). Ensure the connector orientation matches the header pinout and avoid forcing connectors. Route the cable to prevent sharp bends and keep it away from moving parts such as fan blades.

Recommendations

Use this splitter when you need to power or control two 4-pin RGB devices from a single header. Verify compatibility of the RGB pinout and PWM/ARGB signal type before connecting multiple devices to avoid overloading the header or causing signal conflicts.
