5V 3-Pin ARGB Mini Controller Hub Powered by SATA Interface, Addressable RGB Lighting Adjuster for PC Case Cooling Fans, Water Cooling Radiators and LED Strip Light Decoration

This mini 5V 3-pin ARGB controller is a practical lighting expansion accessory for DIY desktop PC builds. It draws stable working power through the SATA power connector of the power supply unit, effectively avoiding overload damage to the motherboards limited ARGB pins.

Equipped with multiple 5V 3-pin addressable RGB output ports, it can centrally connect case cooling fans, CPU water cooling radiators, chassis decorative LED light bars and other ARGB lighting devices. Users can manually switch dozens of preset lighting modes via the physical control button, including static color, gradient flow, breathing, marquee flash and speed regulation without relying on motherboard software synchronization.

The ultra-small lightweight structure comes with self-adhesive backing, allowing you to attach it to the chassis back panel, hard drive bay or empty internal gap for clean cable routing and better airflow. Built-in overcurrent and short-circuit protection circuit safeguards LED components and power supply from accidental burnout.

It is perfectly suitable for gaming PC assembly, RGB customized host modification, workstation cooling system decoration and small-sized ITX chassis lighting centralized control.
