RGB Y-Cable Alphacool 18705 5V Black 300mm

The Alphacool 18705 RGB splitter cable is a sleeved 3-pin aRGB Y-splitter designed to connect and power multiple addressable RGB components in a PC cooling or chassis setup. It is compatible with Alphacool aRGB products and with most motherboards and aRGB controllers that use the 5V 3-pin aRGB standard. The cable is black, made from durable materials and has a length of 300 mm.

Advantages

This 3-pin to 2x 3-pin Y-splitter provides a neat and compact solution for expanding aRGB connections without the need for additional controllers. The sleeved design improves cable routing and protection, while the universal 5V aRGB pinout ensures broad compatibility with compatible devices.

Suitable for

• Connecting two addressable RGB fans or LED strips to one 5V aRGB header
• Expanding aRGB headers on motherboards with limited ports
• Linking multiple Alphacool aRGB components in a cooling loop

How to use

Connect the single 3-pin 5V aRGB male connector to a compatible motherboard header or aRGB controller. Then plug the two 3-pin female connectors into the addressable RGB devices you wish to power and control. Ensure correct orientation of the 3-pin connector to match the 5V, data, and ground pin positions before powering the system. After connections are secure, configure lighting in your motherboard or controller software as needed.

Recommendations

Confirm that your motherboard or controller supports 5V addressable RGB (aRGB) and observe correct pin alignment to avoid damage. Do not connect a 5V aRGB splitter to a 12V RGB header. Avoid excessive bending near connectors and route the sleeved cable to prevent interference with moving parts.
