Corsair K100 RGB Review

Corsair K100 RGB full-size flagship mechanical keyboard, Cherry MX Speed or OPX optical-mechanical switches, 8000Hz Axon polling, iCUE RGB, aluminum frame.

The K100 RGB is Corsair's halo full-size board: an anodized aluminum-brushed frame, a control wheel and dedicated macro keys, and Corsair's Axon processing pushing polling up to 8000Hz for near-instant input readout. It ships with either Cherry MX Speed switches or Corsair's own OPX optical-mechanical switches for buyers who want light-based actuation.

Comparison to Alternatives

Against the Corsair K70 Max, the K100 RGB keeps fixed-actuation mechanical or optical switches rather than the K70 Max's magnetic Hall effect sensors, but adds a control wheel, dedicated macro column, and USB passthrough the K70 Max lacks. Compared with the Razer BlackWidow V4 Pro, the K100 RGB matches its 8000Hz polling claim while offering Corsair's iCUE ecosystem instead of Razer Chroma/Synapse.
