Corsair relaunches popular gaming keyboard with optical switches

Corsair has just launched a new optical-mechanical keyboard, the K70 RGB TKL Champion Series. It’s not an entirely new device, as it’s a refresh of an existing product, but it’s the first K70 with the optical-mechanical design.

The keyboard, primarily aimed at gamers, features a tenkey-free design and quick response times.

Optical keyboards use infrared light and photoelectric switches in order to track keypresses and react to them faster. To that end, Corsair’s new keyboard certainly seems like it will be pretty fast. The company talked about the keyboard in a blog post, describing the features that are said to make the K70 RGB TKL a viable contender on any list of the best gaming keyboards.

The optical-mechanical key switches used in this keyboard have a short 1.0mm actuation distance. Corsair also enables 8,000Hz hyperpolling, which means that every keystroke will be transmitted to the PC really quickly. Corsair promises to be up to 8x faster than standard gaming keyboards, but it doesn’t divulge any particular models to compare the K70 RGB TKL to.

Corsair’s new device seems to offer a good mix of durability and performance. The frame is made out of aluminum and the PBT double-shot keycaps have been precision-molded in order to stand the test of time and wear and tear. Corsair guarantees that each switch will be able to last through a whopping 150 million keystrokes.

Aimed at gamers, the keyboard seems to also be prepared for esports at large, with features that are useful for travel and various tournaments. It connects via a USB-C cable that can be removed at any time in order to pack it up, and it has a switch at the back that helps users follow tournament rules. The switch locks the RGB lighting to a static color and also disables all keyboard macros, ensuring that the player is unable to use them while competing.

Although the switch will not be useful to the majority of users — after all, how many of us are esports champions — the keyboard itself looks like quite a treat for gamers who care about input speed and accuracy. The fancy RGB lighting is just a bonus, and it’s very customizable, too. Using Corsair’s proprietary iCUE software, you can program each key and save up to 50 lighting profiles. The keyboard comes with onboard storage that lets you save these profiles and bring them with you if you travel.

Corsair K70 RGB TKL is already available directly from Corsair’s official website, priced at $150. An older variant of the keyboard seems to have received a discount on Amazon and is now much cheaper at just $100, making it a decent alternative, but one that lacks the optical capabilities that the latest model provides.

Corsair’s K65 RGB Mini revitalizes mainstream 60% keyboard goodness
corsair k65 rgb mini review nmb0151

Sixty-percent keyboards have been around for quite a while, but they haven’t gained much mainstream traction. Last summer, Razer introduced its Huntsman Mini, which showed the world that big companies can do 60% after all, and today Corsair is introducing its own contender: The K65 RGB Mini.

Going in a total opposite direction from the full-size K100 RGB, the K65 RGB Mini cuts off not only the numpad, but also dedicated arrow keys, the F-row, media keys, volume roller, and the delete/home/navigation island. That's quite a few sacrifices to make with the switch to 60%. There’s a good reason for all this butchery, of course: The space freed up gives you more room for mousing around, which comes in handy in gaming.

The Keychron K8 is the mechanical keyboard for Mac that (almost) has it all
keychron k8 mechanical keyboard review 3

Finding a good mechanical keyboard can be a complicated affair. The search is made worse if you are a Mac user and want one that plays nice with your device, as the mech market is heavily tilted toward Windows users. The Keychron K8, however, might be just what you are looking for.

That is because it is a rare breed: A mechanical keyboard that comes with a Mac layout. By default, all the keycaps are ready-made for Mac use (there are Windows keycaps in the box if you want to switch). There are even dedicated Siri/Cortana and screenshot buttons (great on a Mac). Throw in a very reasonable starting price of $69 (most quality mechanical keyboards are $100-plus) and we are off to a good start.

Corsair K100 RGB hands-on: Packed with RGB and ready to party

When Corsair asked if I wanted to have a go at the new K100 RGB, I instantly knew I had to say yes. I owned the first K70 mechanical keyboard as a kid, and given that I haven’t used a Corsair plank in what feels like almost a decade, putting the new K100 on my desk had me feeling warm and fuzzy inside. And unlike many keyboards that pass through my office, this one actually stayed on my desk for the duration I had access to it, so spoiler alert: Yes, I like it.

In Corsair’s pitch, the company said the new K100 has “the most RGB we’ve ever put in a keyboard." If that isn’t cause for concern, I don’t know what is. But Corsair has managed to build a keyboard fitting of this bold claim, without overdoing it on the RGB.
