RGB splitter cable Alphacool 18708 5V Black 300mm

The Alphacool 18708 RGB splitter cable is a sleeved 3-pin aRGB Y-splitter designed to connect multiple 5V aRGB components. With a 300mm length and durable construction, it allows combining several aRGB elements into a single 3-pin aRGB header for synchronized lighting control. The cable is compatible with Alphacool aRGB products and with most motherboards and aRGB controllers that use the 3-pin 5V standard.

Advantages

The sleeved design improves cable durability and routing while minimizing visible wiring. Built for the 5V aRGB standard, the splitter supports multiple devices from a single header without requiring additional power connectors. Its 300mm length offers flexibility for tidy installation inside standard PC cases.

Suitable for

• Connecting multiple 5V aRGB fans or LEDs to one 3-pin aRGB header
• Linking Alphacool aRGB products to motherboard or controller headers
• Expanding lighting zones in PC builds without extra controllers

Route the sleeved cable to reduce interference with other components and secure connectors so they remain seated during operation.

Recommendations

Do not exceed the current rating of the motherboard header or controller when connecting multiple LEDs or fans; consult your motherboard/controller manual for maximum supported load. Use this splitter only with 5V 3-pin aRGB-compatible devices to prevent damage.
