When you're buying RGB components, you're bound to run into these terms sooner or later. Not only are they functionally different but they are visually quite distinct too. This makes understanding the distinctions between them quite critical. RGB or ARGB headers are used to connect RGB LED strips and other RGB accessories to your PC.
However, an RGB header (usually a 12V 4-pin connector) can only control colors on a strip in a limited number of ways. For example, multiple colors on different parts of the strip aren't possible – severely limiting the lighting choices at your disposal.
Here's where ARGB headers come into the picture. An ARGB, or Addressable RGB, header (usually a 5V 3-pin connector) is equipped with an IC (Integrated Circuit, also sometimes referred to as a microchip) to provide much better flexibility with regards to lighting options.
It allows you to enjoy a plethora of lighting effects including, but not limited to, multiple colors on a single LED strip, multiple color changing patterns on a same strip or in sync with other strips connected to ARGB headers.
