The Corsair K70 Core RGB is a wired full-size mechanical keyboard with pre-lubed Corsair MLX Red linear switches, a volume dial and per-key RGB lighting. RTINGS called it an excellent gaming keyboard, citing outstanding latency, good overall build quality and light switches with short pre-travel, though it found the mostly plastic body and ABS keycaps somewhat cheap feeling. PCMag found its internal foam made it noticeably quieter than boards without foam, but judged it a feature or two away from being easy to recommend, with no hot-swappable switches and a gummy feel to some keys. It suits gamers who want a low-latency full-size wired board; anyone who wants wireless, a compact layout or switch swapping should look elsewhere.
Full review
Outstanding latency from light, short-travel switches
RTINGS rates the K70 Core an excellent gaming keyboard for any genre and competitive level, and its testing found outstanding latency performance. It credits the Corsair MLX Red linear switches, which are lightweight with a short pre-travel distance, for a responsive feel in fast, reaction-based games. RTINGS adds that despite the board's minimal feature set, its gaming performance is roughly on par with more expensive models in Corsair's K70 lineup. PCMag notes the polling rate tops out at 1,000Hz, and linear Corsair Red switches are the only option.
Foam dampening inside a mostly plastic shell
Corsair added factory-lubed switches and sound-dampening material to this model, which RTINGS says cut down on the rattle and ping of typing somewhat. PCMag found the internal foam layer made the board noticeably quieter than keyboards without foam, though its list of drawbacks says the sound dampening could be better. PCMag also found the plastic frame resistant to flexing thanks to an internal aluminum plate. RTINGS judged overall build quality good but found the plastic that makes up most of the keyboard, including the ABS keycaps, somewhat cheap feeling.
A short feature list for the price
The K70 Core is wired only: RTINGS points out that it lacks the wireless connectivity of other K70 models, and PCMag notes the switches are not hot-swappable. PCMag also found an odd gumminess to some of the key action. Controls are basic but useful, with a dial that adjusts volume by default and onboard memory for five profiles set up in Corsair's iCue software. PCMag's verdict is that it is not a bad keyboard but is a feature or two away from being easy to recommend, while RTINGS calls it a standout option at a budget price for a straightforward full-size gaming board.
Strengths
- +RTINGS measured outstanding latency, roughly on par with pricier K70 models
- +Pre-lubed Corsair MLX Red linear switches are light with short pre-travel
- +Internal foam makes typing quieter than on boards without any foam
- +Volume dial and onboard memory for five profiles
- +Bright per-key RGB backlighting with shine-through legends
Watch-outs
- −Mostly plastic build and ABS keycaps feel somewhat cheap
- −Wired only, with no hot-swappable switch sockets
- −Linear switches only, and PCMag found some keys felt gummy
How it compares
The Corsair K70 Core RGB is a wired-only full-size board, while the Keychron K2 Wireless and Epomaker TH80 Pro are 75% layouts that also connect wirelessly. It keeps the number pad that the tenkeyless Redragon K552 Kumara leaves off, and it uses linear switches where the K552 ships with clicky blue ones.
