Key specifications

Compact design meets gaming performance

The tenkeyless form factor removes the numeric keypad, giving you more mouse movement space and easier portability. The integrated cable routing system keeps your setup tidy while the 2m detachable USB-C cable ensures reliable connectivity. At just 787g and 147.7 x 367.3 x 55.7mm, it strikes the right balance between stability and portability.

Premium mechanical switches for competitive play

Cherry MX Red switches provide consistent linear feedback with a 45g actuation force, ideal for rapid keypresses in gaming scenarios. The keyboard supports N-key rollover and anti-ghosting, ensuring every keystroke registers accurately even during intense gaming sessions. With a rated lifespan of 100 million keystrokes, these switches are built for long-term durability.

Customisable RGB lighting with AlienFX

The RGB LED backlighting offers full colour customisation through AlienFX software, allowing you to create personalised lighting effects or sync with other Alienware devices. The adjustable backlight intensity means you can optimise visibility for any lighting condition, while the double-shot PBT keycaps maintain legends that won’t fade over time.
