RGB splitter cable Alphacool 18682 Black Plastic 150mm

The Alphacool 18682 RGB splitter cable is a compact 150mm cable for connecting multiple 4-pin RGB or PWM devices to a single motherboard header. Made with black plastic connectors and durable sleeving, it lets you expand a limited number of motherboard RGB/PWM ports without adding a separate hub. The cable supports synchronized power distribution and offers improved cable protection and longevity compared with unsleeved alternatives.

Advantages

The Alphacool RGB splitter provides reliable signal and power distribution to up to four devices from one 4-pin header, reducing the need for additional hardware. Its sleeved construction increases mechanical protection and helps maintain tidy cable routing inside the system. Available in multiple lengths, it allows flexible placement of connected RGB or PWM devices.

Suitable for

• Connecting multiple 4-pin RGB LED strips or RGB fans to one motherboard header
• Expanding PWM fan connections when motherboard ports are limited
• PC builds where a compact, sleeved splitter is preferred over a separate hub

How to use

Connect the single 4-pin end of the cable to the appropriate 4-pin RGB or PWM header on the motherboard, observing pin alignment. Attach up to four compatible 4-pin RGB or PWM devices to the output connectors. After connection, verify device detection and control through the motherboard firmware or RGB control software. Do not force connectors; ensure correct orientation before inserting.

Recommendations

Use the splitter only with compatible 4-pin RGB or PWM headers and devices. Check the motherboard header's maximum current rating to avoid overloading; if total device current exceeds the header limit, use a powered hub or separate power supply solution. Route the sleeved cable to avoid sharp bends and keep connectors accessible for maintenance.
