This article covers CORSAIR K70 RGB TKL CHAMPION OPX Corsair独自OPX軸採用 日本レイアウト テンキーレス 日本語配列 ゲーミングキーボード CH-911901A-JP.

Overview

The CORSAIR K70 RGB TKL CHAMPION OPX is a tenkeyless gaming keyboard featuring CORSAIR's proprietary OPX optical mechanical switches. Designed with a Japanese layout (JIS), it packs pro-grade features into a compact chassis that frees up desk space for mouse movement. The standout technology is AXON Hyper-Processing, which delivers up to 8,000 Hz polling and 4,000 Hz key scanning — dramatically reducing input latency compared to standard gaming keyboards. Built with an aluminum frame, the keyboard feels rigid and durable even during intense gaming sessions. The detachable USB-C cable makes it easy to transport to LAN parties or tournaments, and the tournament switch instantly disables macros and locks lighting to a single color for competition use.

Connectivity & Compatibility

The keyboard connects via a detachable USB-C to USB-A cable. It is compatible with Windows PCs only — macOS, PlayStation, Xbox, and other consoles are not supported. CORSAIR iCUE software provides full control over key remapping, macro creation, and per-key RGB lighting. The tournament switch physically disables macro functions and forces a static lighting profile, ensuring compliance with tournament rules.

Product Info

Released in 2022, the K70 RGB TKL CHAMPION OPX sits in the mid-to-high-end segment. The OPX optical switches are rated for 150 million keystrokes, significantly outlasting traditional mechanical switches. The keyboard carries a 2-year warranty. Included in the box are the keyboard, a USB-C to A cable, a keycap puller, and a quick-start guide.

Best Use Cases

This keyboard is ideal for competitive FPS and battle royale players who need every millisecond advantage. The 8,000 Hz polling rate can reduce input lag by up to 87.5% compared to standard 1,000 Hz keyboards, making rapid flick shots and quick peeks feel more responsive. It also suits gamers with limited desk space. The tenkeyless layout gives your mouse arm more room, which is especially beneficial for low-sensitivity players who make large sweeping movements. Finally, enthusiasts who enjoy customizing their setup will appreciate iCUE's deep lighting and macro options. You can create per-game profiles that automatically switch lighting schemes and key bindings when you launch a title.
