The Corsair K70 series continues its reign with the new K70 Core. Priced at a competitive $100, this mainstream mechanical keyboard boasts high-end features usually reserved for more expensive models. Having used it extensively, I’m ready to replace my two-year-old K100 RGB. Here’s why.

Sleek and Modern Design
The K70 Core retains the full-sized layout and per-key RGB lighting signature of the K70 series, but with a refined, minimalist aesthetic. The trimmed-down bezel surrounding the keys contributes to a smaller footprint, while the robust aluminum top plate and plastic bottom casing provide a sturdy yet surprisingly lightweight feel.
The top right corner houses a configurable metal dial, a customizable media button, and standard status indicators. Two large folding feet offer height adjustment. However, unlike the K70 RGB Pro, the K70 Core features a fixed USB cable instead of a removable USB-C, a curious design choice. A USB pass-through port is also absent.
The standard model sports an all-black finish with yellow accents on the rotary dial. Corsair plans to release special editions with white and grey finishes and varied keycap colors. The keyboard is available with or without a wrist rest. While the magnetic attachment is convenient, the all-plastic construction and low angle of the wrist rest feel less comfortable than the K100 RGB’s.

Feature-Rich Functionality
The K70 Core’s standout feature is its multi-functional metal dial, borrowed from the K100 RGB. Its textured, cylindrical design is a significant improvement over previous iterations. By default, it controls volume, with a press to mute/unmute. Corsair’s iCUE software unlocks further functionality, enabling zooming, scrolling, and backlight brightness control. Switching between functions is achieved via iCUE or the Fn + F12 keys, with a colored indicator on F12 displaying the active function.

While the dial is excellent, it relies on iCUE for advanced functionality, reverting to basic volume control without it. Furthermore, despite its presence on the K100 RGB for three years, Corsair hasn’t added new actions or custom assignments.
A dedicated media control button, customizable via iCUE, offers default play/pause functionality. Additional media controls, backlight brightness adjustment, profile switching, and Windows lock are mapped to the function keys. iCUE provides comprehensive RGB lighting control, although more effects would be welcome. The keyboard supports up to five custom profiles, macro storage, and on-the-fly macro recording.

Superior Switches and Keycaps
The K70 Core features Corsair’s new MLX Red linear switches, pre-lubricated for a smooth typing experience. These switches boast 45g actuation force, 1.9mm actuation distance, 4mm total travel, and a 70 million keystroke lifespan. The double-shot ABS keycaps feel robust and allow RGB backlighting to shine through clearly printed primary and secondary legends.

Two layers of sound-dampening EVA foam contribute to a satisfying “thocky” sound and reduce noise. While my K100 RGB’s Cherry MX Speed Silver switches are responsive, the K70 Core’s MLX Reds offer a smoother, more refined typing experience.
Performance and Value
The K70 Core excels in gaming. The 1000Hz polling rate, while not esports-grade like the K70 RGB Pro’s 8000Hz, is sufficient for most gamers. I experienced no missed keystrokes during intense Apex Legends sessions.

Conclusion
The Corsair K70 Core is a compelling addition to the K70 lineup. It delivers a fresh take on the classic K70 design, with impressive features like the MLX Red linear switches and multi-function dial, all at an affordable price. While the wrist rest could be improved, the K70 Core offers exceptional value and performance, outshining even some flagship keyboards. At $99.99, it competes with options like the SteelSeries Apex 7 and Razer BlackWidow V3, but the K70 Core’s superior switches and included features make it a compelling choice.
