The DeepCool A-RGB Controller is designed to remotely control addressable RGB lighting effects simply without having to install any clunky software. The A-RGB Controller system includes a receiver unit and a magnetic remote controller to easily attach to any steel case.Just plug in a 3-pin A-RGB wire and SATA power cable to the receiver and the remote controller can wirelessly control numerous lighting effect presets.The remote controller is powered with a 3V button(CR2025) battery. Just in case the battery runs out on the remote controller, the receiver unit features a button to manually switch lighting functions or turn on/off.For added functionality, the receiver unit can also be attached to the front I/O reset button for convenient control outside the case. With the included adaptor, the A-RGB Controller can also control any non-DeepCool A-RGB products that have a standard 3-pin 5V A-RGB connector.
