KEEP A LOW PROFILE

SK621
 
Be the envy of chiclet keyboard fanboys everywhere with the ultra-portable SK621 Wireless 60% Mechanical Keyboard. With extra-flat contoured keycaps and new Cherry MX Low Profile switches in a stripped-down 60% format, you’ve finally found a portable wireless keyboard that delivers on performance - without sacrificing the clean aesthetics of your slick workstation. And with signature Cooler Master features on deck, you’re fully equipped to crush it both at work and in-game.
 
 
GET ATTACHED -
BUT ONLY IF YOU WANT TO
The SK621 comes with hybrid wireless functionality, giving you the choice of clean, wireless freedom or lag-free wired functionality. Bluetooth 4.0 connectivity features lower power consumption (4-5 months with lighting off, 15 hours with RGB), combined with a large internal battery that’s rechargeable with the USB-C cable. Who says you can’t have your cake and eat it too?
 
PORTABLE,
LOW PROFILE STYLING
FOR SLIM CLICKINS'
The SK621 sports a bold new look for mechanical keyboards with new Cherry MX Low Profile switches. All the durability and precision of traditional Cherry MX switches, now with a travel distance and actuation point reduced by 0.8mm. Add in ultra-flat doubleshot keycaps and a bare-minimum 60% format, and you have a high-performance mechanical keyboard in a body you can almost fit in your pocket.
 
Think (Same Same, But) Different.
The SK621 takes the classic slim, minimal design of the most popular chiclet keyboard and injects it with the signature Cooler Master mix of flair and functionality. This includes a brushed aluminum top plate for durability and contemporary good looks, while a contoured floating key design gives you a 1-2 punch of functionality and signature beauty. The result is a keyboard that looks familiar, but feels unlike any other chiclet-style keyboard you’ve used before..
 
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 SK621 combats that with an innovative On-the-fly System. Easily adjust per-key backlighting, switch lighting modes, and even record macros 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.
 
 
RGB BACKLIGHTING AND RING
RGBs have never been more elegant than on the SK621, with per-key backlighting that’s implemented with understated functionality in mind. Add in a RGB Ring that adds classy ambience to the setup, and you have the first mechanical keyboard that elevates backlighting to “pinky up” status.
 
NEW & IMPROVED
EASY-TO-USE
SOFTWARE
You don’t need it, but we have it. Simple, straightforward, and fool-proof. You’ll be able to unleash 16.7 million colors to every key, get further customization of lighting modes, and fine-tune macros.
 
 
ACCURACY. REDEFINED.
While plugged in, the SK621 uses N-key rollover technology that results in the most efficient, accurate anti-ghosting technology yet. N-key rollover ensures that every single keypress is correctly detected, even during your most heated, button-mashiest moments - or your chaotic crunch-time coding situations. Ready to take it wireless? For increased battery life, we employed auto-switching technology that gives you 6-Key rollover for your on-the-go, portable lifestyle.
 
FAST, SEAMLESS
PERFORMANCE
Say goodbye to rage quits due to crappy hardware. The SK621 comes equipped with a 32-bit ARM Cortex processor for consistent precision and performance. Register keystrokes instantly. Save and execute commands and macros in a snap. Thanks to the On-the-fly System, get an instant advantage over your opponent and beat them to the punch every time.
THREE SIZES,
THREE WAYS TO PLAY
Everyone has different keyboarding needs, so we’ve engineered the SK600 series accordingly. Whether you need a 60% keyboard for a portable professional setup, a tenkeyless config for a clutter-free home office, or a full-sized board because you’re overcompensating, we have the keyboard you want - with no compromises in features or performance.
