Internal Power Cable Alphacool 18604 0.15m 3-pin Molex

The Alphacool 18604 internal power cable is a 0.15 m adapter cable that converts from a 3-pin JST aRGB connector to a 3-pin 5V connection. It is compatible with Alphacool aRGB devices that use a 3-pin JST plug and enables connection to a wide range of motherboards and aRGB controllers. The cable is lightweight (4 g) and intended for internal PC power routing where a short, reliable adapter is required.

Advantages

This adapter provides straightforward compatibility between 3-pin JST aRGB-equipped Alphacool components and standard 3-pin 5V aRGB headers or controllers. Its short 0.15 m length reduces cable clutter inside the chassis while the lightweight construction keeps added mass to a minimum. The simple, single-purpose design makes installation quick and reduces the need for additional converters.

Suitable for

• Connecting Alphacool aRGB devices with 3-pin JST connectors to motherboard 3-pin 5V headers
• Adapting aRGB components for use with third-party aRGB controllers
• Short cable routing inside compact PC cases

How to use

Locate the 3-pin JST aRGB connector on the Alphacool device and plug it into the corresponding end of the adapter. Connect the 3-pin 5V end to the motherboard aRGB header or to an aRGB controller port, ensuring correct pin alignment. Power on the system and configure aRGB control settings via the motherboard software or the external controller as required.

Recommendations

Ensure pins are correctly aligned before applying power and avoid forcing connectors; use this cable only for compatible 3-pin 5V aRGB connections. For reliable lighting control, verify the motherboard or controller supports 5V aRGB signaling.
