Manufacturer description
The Corsair K100 RGB is built around CORSAIR AXON Hyper-Processing Technology, which drives native 4,000Hz hyper-polling and 4,000Hz key scanning for up to 4x faster throughput than a standard gaming keyboard. Underneath the double-shot PBT keycaps sit CORSAIR OPX RGB optical-mechanical switches with a 1.0mm actuation distance and smooth linear travel, rated for 150 million keystrokes, so the shallow trigger point stays consistent across years of competitive play. The aluminum frame anchors a per-key RGB layout plus a 44-zone three-sided LightEdge, and AXON drives up to 20 layers of lighting…

Frequently Asked Questions
What switches does the Corsair K100 RGB use?
CORSAIR OPX RGB optical-mechanical switches with a 1.0mm actuation distance and smooth linear travel, guaranteed for 150 million keystrokes. This model is linear only, with no tactile or clicky option.
Is the K100 RGB actually faster than a normal mechanical keyboard?
Corsair rates it at up to 4x faster keypress registration than standard mechanical gaming keyboards, using AXON Hyper-Processing with native 4,000Hz hyper-polling and 4,000Hz key scanning.
Is the Corsair K100 RGB wired or wireless?
Wired. This is the wired QWERTY US layout version, so there is no Bluetooth or 2.4GHz receiver in the box.
Does it work with an Elgato Stream Deck?
Yes. The six dedicated macro keys integrate with Elgato Stream Deck software, so you can program streaming commands directly, and the keyboard is also iCUE compatible for lighting and macro profiles.
Are the keycaps good enough to last?
They are double-shot PBT, so legends are molded rather than printed and will not wear off with use. Check the product listing for current warranty terms.
