Corsair K70 RGB MK.2

Overview

The Corsair K70 RGB MK.2 is a mechanical gaming keyboard engineered for durability and performance in competitive gaming environments. Released as an update to the original K70, this iteration retains the brushed aluminum frame, a feature that contributes to its stability and resistance to flex during intense gameplay. The keyboard is equipped with genuine Cherry MX mechanical switches, offering a range of tactile, linear, and clicky options to suit different user preferences. Common switch choices include Cherry MX Red for smooth, linear actuation, Cherry MX Brown for a tactile bump without an audible click, and Cherry MX Speed/Silver for faster keypress registration due to a shorter actuation distance. This variety allows users to select a switch type that aligns with their specific gaming style or typing needs, as detailed in RTINGS' Cherry MX Red switch analysis.

Each key on the K70 RGB MK.2 features individual RGB backlighting, offering extensive customization through Corsair's iCUE software. Users can program per-key lighting effects, create intricate lighting patterns, and synchronize these effects with other iCUE-compatible Corsair devices, such as mice, headsets, and PC components. The software also provides tools for macro programming, allowing users to assign complex sequences of commands to single keys or dedicated macro keys (if present on the specific K70 variant). This level of customization is particularly beneficial in games requiring rapid command execution or for streamlining workflow tasks.

Targeted towards serious gamers and users who require a robust, responsive input device, the K70 RGB MK.2 includes features like 100% anti-ghosting with full key rollover, ensuring that every command is registered accurately regardless of how many keys are pressed simultaneously. A dedicated volume roller and multimedia controls are integrated, providing convenient access to audio adjustments without needing to alt-tab out of a game. It also includes a detachable soft-touch wrist rest for ergonomic support during extended use. The keyboard's USB pass-through port allows for easy connection of a mouse or headset directly to the keyboard, reducing cable clutter on the desk. This blend of durable construction, customizable performance, and user-centric features positions the K70 RGB MK.2 as a suitable option for high-performance gaming setups and professional esports players seeking reliability and precise control. Esports professionals often utilize such durable keyboards for their consistent performance, as documented by ProSettings.net's professional player gear lists.
