Review on EZDIY-FAB RGB Converter: 12V to 5V ARGB Transfer Hub with 3-Way Splitter - Control 5V ADD-RGB Products on 12V 4-pin Header, 50 Built-in Color Modes by Tony Dago

Bought to use on an Asus B450-F gaming motherboard which only had 4 pin RGB 12V headers and this little unit did exactly what it said it would promised. I plugged in my A-RGB fixture from the same manufacturer and was able to instantly sync it with the Asus Armory RGB software. Comes with additional cables to add more RGB elements with 3 pins 5V (like or light strips). Highly recommended if your board doesn't have proper lamp and fan connectors. It also has its own pre-programmed lighting schemes, which are really nice and can be installed separately from your motherboard's RGB capabilities if you want to tweak it a bit. :)
