An ARGB hub is a device used for the centralized connection and control of multiple components with addressable RGB lighting inside a computer case. The abbreviation ARGB stands for "Addressable Red Green Blue." Unlike older RGB lighting, where all LEDs shone in a single color, ARGB technology allows for individual control of each individual LED. This makes it possible to create advanced lighting effects, such as smooth color transitions, rainbow waves, or other dynamic animations. Computer motherboards usually have only a limited number of connectors for attaching ARGB devices, often just one or two. If a user wants to connect multiple elements, such as several fans, a CPU cooler, and LED strips, they will encounter a shortage of ports. This is exactly the problem an ARGB hub solves. It acts as a splitter that creates multiple outputs from a single signal from the motherboard. The hub itself connects via a single cable to the appropriate 3-pin 5V ARGB connector on the motherboard and typically draws power directly from the computer's power supply using a SATA connector. All illuminated components are then plugged into the ports on the hub. As a result, all connected lighting can be controlled synchronously via the motherboard manufacturer's software as a single device. This simplifies not only the setup of lighting effects across the entire build but also cable management inside the case.
