B365M Motherboard banner showing close-up spots of the two RGB LED headers and addressable RGB LED header

This motherboard features onboard RGB headers and an addressable RGB header that allow the motherboard to be connected to compatible LED devices such as strip, CPU fans, coolers, chassis and so on. Users may also synchronize RGB LED devices across the Polychrome RGB Sync-certified accessories to create their own unique lighting effects.


The addressable RGB LED header supports a WS2812B addressable RGB LED strip (5V/Data/GND), with a maximum power rating of 3A (5V), a max of 80 LEDs and an overall length within 2 meters.
The RGB LED header supports standard 5050 RGB LED strips (12V/G/R/B), with a maximum power rating of 3A (12V) and lengths within 2 meters.
