Corsair K100 RGB

Corsair K100 RGB

The Corsair K100 RGB was introduced on the first of October 2020 as their new flagship gaming keyboard. Its looks are somewhat similar to what we have seen from K95 keyboards, but there are quite some updates and new features that justify the keyboard‘s new name.

The Fastest Keyboard in the World

The Corsair K100 RGB is the first keyboard with AXON Hyper-Processing Technology. This is a fancy term for saying the keyboard works with a polling rate up to 4,000 Hz, so it basically scans up to 4,000 times per second for new keypresses. Common gaming keyboards work with a polling rate of 1,000 Hz or 125 Hz. The differences in numbers are big, but the step from 1,000 Hz to 4,000 Hz will hardly be noticed, since a rate of 1,000 Hz already means that keypresses are recognized every millisecond. Still, it sure has some coolness-factor to own the fastest keyboard in the world.

Corsair’s new keyboard is not only fast but also well-equipped for gaming in general. Thanks to NKRO, an arbitrary number of keys can be pressed at once and will be recognized reliably. The gaming mode disables the windows key and (if desired) other keys that could lead to accidentally minimizing a game. The RGB illumination is fantastic and even includes a 44-zone light edge that runs along the sides and the top of the keyboard. Countless lightning effects and customization options are available. Different configurations can be stored in separate profiles so that custom settings for users or applications are easily managed. There is also an on-board memory to store profiles and use them, even when on a different computer.

Debut of Corsair’s Opto-Mechanical Switches

The keyboard is also the first to feature the company’s new opto-mechanical switch type Corsair OPX. Instead of establishing a metal contact, the switches actuate by using a light signal. This removes the need of waiting for debouncing and further eliminates some possible error causes. Corsair is therefore another big company putting efforts into opto-mechanical switches. Especially the Razer Huntsman series has recently pulled a lot of attention to these new kind of switches. The new Corsair OPX switches are not the only option for the K100 RGB though, you can also buy the keyboard with Cherry MX Speed. These linear switches are known for their short actuation distance and are a popular choice in gaming.

Packed full of Features

It’s difficult to find anything that the Corsair K100 RGB doesn’t offer. The keyboard comes with a volume wheel and several media controls for typical functions such as mute, pause, stop, previous and next. Six dedicated macro keys can be used for custom commands, but also every other key can be freely reprogrammed with Corsair’s software. Just like the K95 XT, the keyboard also supports Elgato Stream Deck software. Furthermore, there is a USB passthrough to easily connect any USB device via the keyboard.

Another highlight of the Corsair K100 RGB is its new iCUE control wheel. It can serve various purposes such as zooming, switches between applications or controlling the brightness. These functions are configured via Corsair’s software (iCUE) and can be swapped by pressing the wheel.
The keyboard gets delivered with a cushioned palm rest and extra key caps for MOBA and shooter games. Also, a keycap puller to easily swap the key caps out is included.

"While the K100 RGB is the new hotness for Corsair, full of features and highly customizable, the cost is the thing that will keep many customers away. While worth the cost to some extent, it is likely the one thing that will turn some away."

"Corsair’s latest keyboard is absolutely its greatest. It’s not perfect, as I’ll get to, but it’s a strong premium contender and a worthy new flagship. ... Sadly, there are some design hiccups that keep it back from our most prestigious award."
