Cavo splitter RGB Alphacool 18702 5V nero 300mm

The Alphacool 18702 RGB splitter cable is a 5V aRGB extension that converts a single 3-pin aRGB connection to an additional 3-pin (5V) output. Constructed from durable plastic with a black finish and a cable length of 300 mm, this splitter enables connection of multiple aRGB devices to a single header for coordinated lighting control. It is compatible with Alphacool aRGB products and with most motherboards and aRGB controllers that use the 3-pin 5V aRGB standard.

Advantages

This 3-pin to 3-pin (5V) splitter provides reliable signal and power distribution for multiple aRGB components while maintaining a compact and discreet appearance. Its 300 mm length offers flexible routing inside PC cases, and the black plastic construction resists wear and visually integrates with most builds. The cable’s compliance with the 5V aRGB standard ensures broad compatibility with Alphacool devices and common motherboard headers or external aRGB controllers.

Suitable for

• Connecting additional Alphacool aRGB fans, LED strips, or blocks to a single 3-pin 5V header
• Extending a single motherboard aRGB output to control multiple lighting devices
• Small to mid-size PC builds where short cable runs and neat cable management are required

How to use

Power off the system before connecting the splitter. Plug the single 3-pin (5V) male connector into the motherboard or aRGB controller header, then attach the additional 3-pin female connectors to the Alphacool aRGB devices you want to control. Arrange cables to avoid strain on connectors and ensure the devices share the same 5V aRGB signal for synchronized lighting. Power on the system and use your motherboard or controller software to configure lighting effects.

Recommendations

Use this splitter only with 3-pin 5V aRGB headers and devices. Do not connect to 4-pin 12V RGB headers. Avoid overloading a single header—check your motherboard or controller maximum current rating and the combined current draw of connected devices before attaching multiple components.
