The SteelSeries Apex Pro Mini Gen 3 (8.6) beats the Corsair K70 CORE RGB (8.5): owners are about as happy with both, and it is the newer design.

About the Corsair K70 CORE RGB

The K70 CORE RGB has 105 keys in a UK layout, including a numpad. The switches are Corsair MLX Red v2 linears, lubricated at the factory, under double-shot ABS keycaps. Two layers of sound-dampening foam sit inside the case, under an aluminium top plate.

A rotary dial in the top-right corner handles volume, RGB brightness, zoom, scrolling and other functions, which you can reassign in Corsair's iCUE software. iCUE (Windows 10, and macOS 10.15 or later) also covers per-key lighting, macros and key remapping. The board stores up to five profiles on its own memory, so settings travel to a PC without iCUE. It has full N-key rollover, a 1,000Hz polling rate and adjustable height. FlashTap, an input-priority setting for games, is off by default and needs the latest firmware.

The cable is a fixed, tangle-free rubber lead with a USB Type-A plug. Corsair sells the board with or without a detachable magnetic soft-touch palm rest, so check which version you are buying. In the box: the keyboard, a safety leaflet, a warranty card and an online quick start guide. Club386 measured the board at 448mm by 135mm, or 210mm deep with the palm rest fitted.

What owners report about the Corsair K70 CORE RGB

We found little owner feedback for this exact model on the pages we could open, so we do not report an owner pattern here. The points above on the palm rest and cable come from the Club386 review, not from owners.

Who the Corsair K70 CORE RGB suits

It suits anyone who wants a full-size board with a numpad and a quiet linear switch, for games and for daily typing. The dial and onboard profiles are handy if you move between PCs. Club386 found the plastic palm rest uncomfortable and suggested the version without it plus a separate padded rest.

Look elsewhere if you want wireless: Keychron V6 Max is a full-size wireless board in a UK layout. The switches are not hot-swappable and the cable is fixed, so a board you can modify or repair will suit you better. For rapid trigger and adjustable actuation, SteelSeries Apex Pro Gen 3 is the full-size choice.

Questions about the Corsair K70 CORE RGB

How we score it

Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
