RGB Splitter Cable Alphacool 18729 Plastic White 300 mm

The Alphacool 18729 RGB splitter cable is a 300 mm plastic, white 4-pin to 4x 4-pin cable designed to connect and control multiple RGB/PWM devices from a single motherboard header. It lets you expand a limited number of motherboard RGB or fan connectors without adding a separate hub. The cable features protective sleeving for improved durability and cable management.

Advantages

The splitter provides a compact and cost-effective way to power and synchronize up to four RGB or 4-pin PWM devices from one header. Its sleeved construction increases mechanical protection and reduces wear, while the 300 mm length gives flexibility when routing inside PC cases. No additional fan/RGB HUB is required when using compatible headers.

Suitable for

• Connecting multiple RGB LED strips or RGB fans to a single motherboard RGB header
• Expanding PWM fan connections from one 4-pin fan header
• Improving cable routing in compact PC builds
• Synchronizing lighting or fan speed across several components
