The RGB header on the motherboard controls the LEDs using digital signals. The RGB pulse-modulated signal controls a lighting strip’s red, green, or blue LED. The motherboard connects to the RGB header through a 4-pin standard connector, ensuring all RGB components work together.[3]

There are two variations of these 4-pin connectors: 12V and 5V.[4] The difference between these two connectors is the amount of electricity they can provide and how they transfer RGB data signals.

Digital signals in the 5V RGB headers can control the RGB lighting, and the 12V RGB headers use a voltage control system. When selecting an RGB lighting system, the header voltage must match the lighting system voltage. The majority of motherboards have both 12V RGB headers and 5V RGB headers. To ensure compatibility, always verify the manufacturer’s specs.

The motherboard’s BIOS offers RGB control through the manufacturer’s software, but opt for third-party software if you’re looking for some advanced features. Users can adjust the lighting effects, speed, brightness, and other features using 3rd party software from companies like ASUS, Gigabyte, Corsair, and others.[5]

Every software has some unique options and features. Ultimately, RGB header systems offer an immersive visual experience that improves aesthetics and user experience.

What RGB Components Can I Control With The RGB Header On The Motherboard?

Users control and customize the RGB lights thanks to the motherboard’s RGB header. When it comes to RGB lighting, the possibilities are unlimited. Depending on the user, a variety of options are accessible. However, the type of components varies depending on the system.

Some common RGB components that you can control with the motherboard’s RGB header are listed below:

  • RGB Fans: LED lights included with RGB fans produce an immersive visual experience controlled by RGB headers.[6]

What Should You Do If the Motherboard In Your System Has No RGB Header?

If you have a new build or are upgrading your PC, you might have encountered the problem of your motherboard not having an RGB header. You can resolve this issue easily by opting for one of the alternatives, but it will cost you extra money.[2]

USB RGB Controller

A USB RGB controller is one technique to add RGB lights to your computer without an RGB header. You may use these controllers to control the lighting of your RGB strips or other devices by plugging them into a USB port.[7] They are simple to use and quite inexpensive.

External RGB Controller

An external RGB controller is an object that resides outside your computer casing and controls your RGB lighting. Although these controllers can cost more than Molex or USB controllers, they provide advanced settings and customization.

Install A Lighting Node Pro

A Lighting Node Pro can control the lighting of your Corsair RGB lighting strips. You can control lighting using Corsair’s iCUE software with this device connected to a USB header on your motherboard.[5]

RGB Splitter Cables

An RGB splitter cable will allow you to operate many RGB devices with a single controller. These cables allow several devices to connect to a single RGB controller for easy setup.[8]
