general information

Cooler Master engineers went to work on how to effectively design a keyboard with superior switches and the brightest LED backlighting. They gutted the interior and redefined RGB backlighting by modifying the printed circuit board (PCB) with small cutouts to let the LEDs sit snugly against the switches.

That means they are still able to use genuine Cherry MX switches with their RGB housing and larger, brighter LEDs. The concentrated light under the keycaps will let your keyboard's LEDs pop and shine with vibrant colors. No dull muted colors here.

Exclusive Anti-ghosting Technology

Exclusive anti-ghosting technology features two technologies rolled into one. The MasterKeys Pro L has combined N-key and 6-key rollover together, ensuring each keypress is correctly detected regardless of how many keys are pressed. If seven or more keys are pressed, it automatically switches over to N-key rollover. Rest easy knowing no matter how fast and furious it gets, your keyboard can handle it. Keyboard’s functions and macros are compatible also with macOS systems (macOS uses 6-key rollover only).
