Review: Corsair K70 Core



Let’s move on to testing the K70 Core. We put it to the test in just about every scenario: video games, office automation, etc…


Handling the K70 Core is classic! In fact, it’s a 104-key keyboard, so there’ll be no change if you’re used to this type of keyboard. What’s more, if you’ve been using Corsair keyboards until now, unlike the Corsair K100 RGB, we don’t have any macro keys on the left-hand side of the keyboard. This is rather convenient, as it means we won’t be mistaken for a column when typing… At least until we get used to it.

At the top, coupled with the F.. keys, are the multimedia keys for changing the profile, managing keyboard brightness and blocking the Windows key. As you’ll see from the photos below, there are plenty of shortcuts available on the K70 Core. Moving to the far right, we discover a wheel never before used by Corsair. This allows you to increase or reduce the volume and mute the sound by “clicking” on it. This wheel is very pleasant to use, perhaps even more so than those on previous K70 and K100 models.

PBT keys are a thing of the past here, as this model is available with ABS keys. Nevertheless, given the keyboard’s price (less than 100 euros), it’s hard to hold this against the brand. ABS keys are more likely to show fingerprints and may leave a shiny effect over time. Over time, however, the lettering will last longer because they are double-injected, i.e. the lettering is molded directly into the fingerboard. So, unlike NZXT’s keyboard for example, the lettering will hardly ever fade, and the backlighting remains visible.

The K70 Core has a hard, grainy plastic palm rest. Unfortunately, it’s too flat, so I hardly ever rest my wrists on it. On top of that, it could scratch the skin a little if your wrist is placed on it. It’s a bit reminiscent of the old K70 RGB MK.2.

On this model, the power cable is thin and unsheathed. It’s not very aesthetic, visually speaking. On the other hand, it’s not rigid and clearly won’t get in the way on the desk. It’s a far cry from the double cable of the Roccat Vulcan II Max, for example, which was thick and rigid.


Gone are the customizable switches of the K70 Max RGB. We’re still dealing with Corsair switches, but in their linear version. These are designed to be fast, precise and silent. To activate them, you’ll need 1.9 mm for a force of 45 G. Their total travel is 4 mm and they are guaranteed for 70 million keystrokes. On top of this, these switches have been pre-lubricated, making them smoother, less rough and quieter.

In terms of feel, these are fairly soft switches, since there’s no stop. Linear switches are generally quite sensitive. Indeed, with a force of 45 cN, the key will be activated quite easily, and even more so here with the lubrication. I tend to use double letters on this keyboard when writing. Typing errors are plentiful, as are inopportune movements. On the other hand, for writing, there will be less fatigue than on harder switches, that’s also the advantage.

Corsair equips its K70 Core with a soundproofing layer to limit unpleasant noises. The keyboard base does not act as a sounding board. In use, spacebar noise is greatly reduced. Indeed, on most mechanical references, it will tend to rattle. It’s even quieter than the other keys on the keyboard.

However, this does not mean that the switches are really silent. They have a relatively dry end-of-travel, which generates a “clack, clack, clack” sound that may annoy those around you. However, this noise seems to be what the brand is aiming for.



On this K70 Core, the lights stand out well on the keyboard keys. Overall, the light is intense and well-dosed. What’s more, thanks to keyboard shortcuts or the iCUE software, you can set a wide range of effects, even key by key, on different lighting layers. However, if you’re buying your keyboard for its RGB lighting, you might be better off with a Roccat Vulcan II or Vulcan II Max.
