Competition-Ready Tenkeyless Keyboard

The Corsair K70 TKL is a wired gaming keyboard built around CORSAIR OPX optical-mechanical switches with a 1.0mm actuation point. It uses a tenkeyless layout with 87 keys and a detachable USB-C cable for portability. RGB backlighting supports up to 20 layers of hardware lighting processing. PBT double-shot keycaps at 1.5mm thickness resist wear and shine.

Suited For Tournament Play And Minimal Desk Space

Players who need hyper-fast polling at 8,000Hz and 4,000Hz key scanning will benefit from the optical switch speed. The tournament mode switch instantly locks static backlighting and disables macros for distraction-free matches. Buyers who require a dedicated number pad or an integrated palm rest should look at a full-size alternative. Mac users needing macOS 10.15 or later and a USB 3.0 or 3.1 Type-A port are supported.

Optical Switches Rated For 150 Million Keystrokes

The OPX linear switches deliver consistent actuation across a 150 million keystroke lifespan. PBT double-shot legends will not fade under heavy daily use. The tenkeyless form factor measures 14.17" x 6.46" x 1.57", freeing desk space for mouse movement. iCUE software configuration requires an internet connection and Windows 10 or macOS 10.15+.
