Strike with the Speed of Light
The full-sized CK351 gaming keyboard provides responsive controls in reliable hardware that is rated to last longer than your most intense all-nighters. IP58-rated dustproof and waterproof with state-of-the-art optical switches rated for over 100 million keypresses - and a debounce time that’s virtually instantaneous. Add to that fully custom RGB lighting, media controls, and Cooler Master’s signature On-the-Fly Control system, and you have a steady, rugged workhorse that gets the job done.

Precision Optical Switches Guaranteed to Last
The CK351 is outfitted with the latest and greatest optical switches, top-of-the-line in both durability and responsiveness. They’re rated for over 100 million+ keypresses for maximum longevity, and a debounce time of nearly 0 means that there’s no dead space in switch inputs - and no inputs that go unregistered.

Hot Swappable
Not only are the optical switches top of the line, we’re giving you the option to customize the feel of your typing based on your preferences. Change up your optical switches with a simple plug & play, regardless of your affiliation: linear, tactile, or clicky gang.

No soldering, no accidental burns, no messing with molten wire on your precious baby.

Rugged Design Built for Durability
The CK351 is built to last, with a thoughtful design that’s equal parts minimalistic and rugged. A brushed aluminum top ensures durability, while a floating keycap design makes cleanup easier than ever.

RGB Per-Key Backlighting
No-nonsense backlighting for a no-nonsense keyboard - illuminate your keys based on control schemes, or just do it because it looks cool.

No Software Required
When you’re in a groove, the last thing you want to do is Alt+Tab out to adjust your keyboard settings. The CK351 combats that with an innovative On-the-fly System. In the heat of battle, easily adjust per-key backlighting, switch lighting modes and profiles – all with just a few keypresses. Get the functionality of software without needing to have software bloating your system - saving you time and precious PC resources.

Wrist Rest
Low-friction cloth to keep you comfortable during long gaming sessions.

Resistance From the Elements
As if the rugged housing weren’t enough, the CK351 is IP58-rated for dust and water resistance - proven to protect your gear from accidental spills or filthy battle stations.

MasterPlus+ Suite Support
The CK351 is one of the first Cooler Master products to support the new MasterPlus+ software, a unified control hub where managing all of your Cooler Master gear is easier than ever. Adjust all of your settings from one dashboard, and even sync your lighting settings across multiple devices with ease.
