Glowing keyboards, mice with colour-shifting logos and fans that ripple through the rainbow have become part of the gaming aesthetic. Behind those effects sit two different technologies that look similar on a product box but behave quite differently: standard RGB and addressable RGB, usually shortened to ARGB.
How standard RGB works
Each RGB LED combines red, green and blue light to produce a wide range of colours. In a standard RGB strip or device, all the LEDs on a single channel are controlled together, so the whole strip shows the same colour at the same time. You can choose a colour, make it breathe, flash or cycle, but every LED on that channel does the same thing.
For PC components, standard RGB typically uses a 4-pin 12V connector on the motherboard or controller.
What makes ARGB different
Addressable RGB includes a small controller chip that lets each LED, or small group of LEDs, be set individually. That enables flowing rainbows, chasing patterns, gradients and effects that react to music or in-game events. ARGB for PC components commonly uses a 3-pin 5V connector.
The connectors are not interchangeable. Plugging a 5V ARGB device into a 12V RGB header can damage the LEDs, so always check headers and manuals before connecting anything.
Side-by-side comparison
| Feature | Standard RGB | ARGB |
|---|---|---|
| LED control | Whole channel at once | Individual LEDs or zones |
| Typical PC header | 4-pin, 12V | 3-pin, 5V |
| Effects | Static, breathing, colour cycle | Waves, gradients, reactive patterns |
| Price | Usually lower | Often higher |
Is ARGB worth choosing?
It depends on what you want from your setup. If a single accent colour that matches your desk is enough, standard RGB does the job and often costs less. If you enjoy elaborate lighting, synchronised effects across components or lighting that responds to games, ARGB offers far more creative freedom. A detailed breakdown of ARGB vs. RGB can help when comparing specific products.
Does lighting affect performance?
Lighting itself does not change frame rates or input latency in any meaningful way. Some lighting control software runs in the background and uses a small amount of system resources, and poorly written utilities can occasionally cause conflicts. Keeping software updated, or using a single ecosystem to control all devices, usually avoids these issues.
If you would rather see the difference than read about it, this short video puts both lighting types side by side:
Where you will find each type
Both technologies appear in keyboards, mice, headsets, mouse mats, monitors, case fans, coolers, memory modules and LED strips. Higher-end peripherals more often use addressable lighting, while budget items may stick with standard RGB. Check compatibility with your motherboard or the manufacturer's control software before mixing brands, since not all ecosystems sync smoothly with each other.
