1. Sync with Motherboard Lighting Control: Compatible with for , for , for , for motherboards (5V/3Pin D-RGB interface connected to a 12V/4Pin RGB interface). Through motherboard control, the lighting can synchronize with other RGB products, allowing 5V ARGB devices to be controlled by a 12V RGB motherboard, achieving synchronized color changes. It can also be controlled manually using the controller's buttons. 2. 5V ADD-RGB to 12V RGB Conversion: Convert 5V ADD-RGB devices to be compatible with 12V RGB motherboards. Achieve synchronization and compatibility between different lighting systems. The 12v rgb to 5v argb fer hub can also be used as a manual controller, allowing you to control colors and change speeds using buttons. It can also be connected to the case's reboot button to control color changes. 3. Multiple Button Functions: M key - Built-in 50 color modes, long- for three seconds to switch to motherboard sync mode; Fast Forward key - Controls the speed of color modes (Low/Medium/Fast); A 2-pin interface on the left side of the 5v to 12v rgb fer hub allows connection to the case's reboot button to control external RGB devices connected to the converter. Long- for three seconds to switch to motherboard control. 4. Important Notice: Can only sync with 12V RGB motherboards. The number of RGB signals varies slightly between different motherboards (12V RGB and 5V ARGB). On certain motherboards, some mixed RGB colors may not display correctly (e.g., orange, yellow), and the color itions of LEDs may not be smooth in cycling color mode.
