Overview

The CORSAIR K70 RGB TKL CHAMPION Cherry MX Speed Japanese Layout Gaming Keyboard (model CH-9119014-JP) is a tenkeyless mechanical keyboard co-developed with professional esports players. It features a compact 91-key Japanese layout that saves desk space without sacrificing essential controls. The standout feature is the CORSAIR AXON hyper-processing technology, enabling an 8,000Hz polling rate — up to 8× faster than conventional gaming keyboards. Combined with Cherry MX Speed (Silver) linear switches and a durable aluminum frame, this keyboard delivers exceptional responsiveness for competitive gaming.

Connectivity & Compatibility

Connectivity is via a detachable USB-C cable, ensuring a reliable and modern interface. The keyboard is fully compatible with Windows PCs and can be customized extensively using CORSAIR iCUE software for key remapping, macro programming, and per-key RGB lighting control. A built-in tournament switch instantly disables macros and distracting lighting effects, making it ready for LAN events. It is plug-and-play, no additional drivers required. While not officially supported on macOS, basic functionality works.
