Overview

The Corsair K70 RGB MK.2 LOW PROFILE RAPIDFIRE MX SpeedKeyboard is a premium gaming keyboard featuring Cherry MX Low Profile Speed switches. These switches offer a shorter actuation distance compared to standard Cherry MX Speed, enabling faster response times for competitive gaming. The keyboard uses a Japanese 108-key layout and is built around an anodized aluminum frame for durability. It supports per-key RGB backlighting fully customizable via Corsair's iCUE software, and includes onboard memory for storing profiles.

Connectivity & Compatibility

This keyboard connects via a single USB-A cable (braided, detachable). It includes a USB passthrough port on the rear for connecting a mouse or headset. Compatibility is limited to Windows 10 and later; macOS supports basic typing only (iCUE and advanced features are not available). The keyboard supports full N-key rollover and 100% anti-ghosting, ensuring every keypress is registered even during complex combinations.

Product Info

Released in late 2018, the K70 RGB MK.2 Low Profile sits in the mid-to-high tier of gaming keyboards, with a street price around ¥50,000–¥55,000 in Japan. It comes with a 2-year warranty. Included accessories: textured FPS/MOBA keycap set, detachable magnetic palm rest, keycap puller, and a USB cable. Available from Corsair's official store and major online retailers. Market positioning: a premium low-profile mechanical keyboard competing with the Razer Huntsman Tournament Edition and Logitech G915.

Best Use Cases

Competitive FPS gamers: The low-profile Speed switches provide a lightning-fast actuation point, giving an edge in reaction-based scenarios. However, users who type extensively may find the shallow travel less satisfying. Gamers with limited desk space: The slim profile reduces wrist strain and pairs well with the included palm rest. Note that it's a full-size keyboard, so it still occupies standard width. RGB enthusiasts: iCUE offers deep customization and synchronization with other Corsair peripherals. Keep in mind that the software must be running for advanced lighting effects. Japanese layout users: The official Japanese 108-key layout is ideal for those who need dedicated keys like 半角/全角 and 無変換. Not necessary for users comfortable with ANSI layout.
