Overview

The CORSAIR K70 RGB PRO is the latest evolution of the iconic K70 series, now equipped with Cherry MX RGB Red linear switches and CORSAIR AXON hyper-processing technology. The standout feature is an 8,000Hz polling rate, which processes and transmits keystrokes up to eight times faster than conventional gaming keyboards. This wired mechanical keyboard also features a durable aluminum frame, PBT double-shot PRO keycaps that resist shine over time, and a soft-touch palm rest for extended gaming sessions. It is designed for competitive gamers who demand the fastest possible input response.

Connectivity & Compatibility

The K70 RGB PRO connects via a detachable USB-C cable (USB-C to USB-A included) and is compatible with Windows 10/11 and macOS. A dedicated tournament switch instantly locks the backlight to a static mode and disables accidental macro triggers, ensuring compliance with esports rules. Onboard storage holds up to 50 profiles, allowing you to switch between game-specific layouts without launching iCUE software. The keyboard requires a single USB port for both data and power.

Product Info

Released in 2021, the K70 RGB PRO is priced around ¥63,444 on Japanese online retailers as of October 2026. It comes with a two-year warranty, a detachable USB-C cable, a soft-touch palm rest, and a keycap puller. The iCUE software enables per-key RGB customization, macro programming, and key remapping. Market positioning is high-end: the combination of 8,000Hz polling, Cherry MX switches, an aluminum chassis, and PBT keycaps places it among the top-tier wired gaming keyboards for serious players.

Best Use Cases

  • Competitive FPS gamers: The 8,000Hz polling rate gives a tangible edge in reaction-time-critical titles like Valorant, CS2, and Apex Legends. The linear Cherry MX Red switches allow rapid, smooth actuation. However, if you prefer tactile or clicky feedback, the Reds may feel too light.
  • Heavy typists and content creators: PBT keycaps resist wear and shine far better than ABS, and the aluminum frame with palm rest reduces fatigue during long typing sessions. Note that the keyboard is not particularly quiet; adding O-rings can help.
  • Users building a unified RGB ecosystem: iCUE compatibility lets you sync lighting with other CORSAIR peripherals. Onboard profile storage means you can carry your settings between PCs without reinstalling software.
  • Aesthetics-conscious builders: The brushed aluminum frame and per-key RGB create a premium look that fits clean desk setups. But the full-size layout (with numpad) may be too large for those who prefer tenkeyless or 60% boards.
