The Corsair K70 RGB MK.2 is a versatile keyboard with outstanding gaming performance. It's available in a few different switches, including Cherry MX Brown, Red, Blue, Silent Red, and Speed, so you can get the switches you prefer. The Cherry MX Brown switches we tested are light to press, great for gaming, and offer a great overall typing quality. This keyboard has a ton of extra features like customizable RGB backlighting, the ability to set macros to any key, and a USB passthrough. It's a well-built keyboard, the edges of the aluminum plate on top feel sharp, which could be annoying.

Our Verdict

7.9 Mixed usage

The Corsair K70 RGB MK.2 is a very good overall keyboard. Every key is macro-programmable, it has full RGB backlighting with individually-lit keys, and the keys have minimal pre-travel distance, which is outstanding for gaming. It's a good choice for office use or for programmers because it has a detachable wrist rest and it doesn't feel tiring typing on this keyboard. It's compatible with most common operating systems but the dedicated software isn't available on Linux.

Pros
  • Available in a few different Cherry MX switches.
  • All keys are macro programmable.
  • Great typing quality.
Cons
  • Software not available on Linux.
  • Aluminum edges of the top plate feel sharp.

The Corsair K70 RGB is a full-sized keyboard that takes up a good amount of space. You can remove the wrist rest if you want to save some space.

Build Quality

Good build quality. It's mainly made out of plastic and the top plate is aluminum, giving the keyboard a better build than the Corsair K68 RGB, but the keyboard flexes a bit. The edges of the aluminum are a bit sharp, but this could be a problem with our unit only. The ABS keycaps are stable, with the exception of the spacebar, which has a bit of wobble to it. The keycaps feel nice but they seem like they attract oils from your fingers easily. The keyboard comes with a plastic wrist rest that has a rubber finish to it and feels somewhat hard. Lastly, the cable it comes with is thick and well-made, but if there are any kinks in it, they're hard to remove. If you want a keyboard with a better build quality, check out the SteelSeries Apex Pro.

Wrist Rest Detachable

Good ergonomics. The Corsair K70 RGB has one incline setting and it comes with a basic wrist rest that feels a bit hard, and not as plushy as the Corsair K95 RGB PLATINUM XT. The wrist rest is detachable, but it's a bit hard to remove.

This keyboard has a great number of extra features, similar to most other Corsair keyboards, like the Corsair K68 RGB. It has a USB passthrough, allowing you to attach a device, like a mouse, directly to the keyboard instead of your computer. Every key, except for the 'Profile Switching' and the 'RGB Brightness' keys are macro programmable through the iCUE software, and the Windows Lock Key can be reprogrammed to a few different functions. There are dedicated media keys and a volume wheel at the top right too. However, if you need a keyboard with a Windows lock key, consider the Das Keyboard Model S Professional.

Typing Quality

Great typing quality, similar to the Corsair K68 RGB. The keycaps feel nice to touch and are stable, except for the spacebar, which is a bit wobbly. The Enter and Shift keys aren't as good as most other keys, but they're still fairly stable. It may take some time to get used to the spacing of the keys, which could lead to typos when you first get the keyboard. Also, it shouldn't feel tiring typing on this keyboard, and having the wrist rest helps with fatigue. If you want a keyboard that provides a better typing experience, check out the Razer Pro Type.

Quiet

The Cherry MX Brown switches are quiet and shouldn't bother others around you. However, if you get the Cherry MX Blue switches, they offer clicky feedback, which is distracting for others nearby.

Differences Between Sizes and Variants

We reviewed the Corsair K70 RGB MK.2 in black. It's also available in white, which is sold as the Corsair K70 RGB MK.2 SE, and there's also a low profile variant. The K70 RGB MK.2 is available in a variety of switches, while the other variants are available with limited switch options. The differences between them are listed below.

Name Color Backlighting Cherry MX Switches
Corsair K70 LUX  Black Red Brown, Blue, and Red
 Corsair K70 Rapidfire Black Red  Speed
Corsair K70 RGB MK.2 Black RGB Blue, Brown, Red, Speed, and Silent
Corsair K70 RGB MK.2 SE White RGB  Speed
Corsair K70 RGB MK.2 Rapidfire (Low profile) Black RGB Red and Speed

If someone has a Corsair K70 RGB that's different from ours, let us know in the discussions and we'll update the review.

Compared to other keyboards

The Corsair K70 RGB MK.2 is an outstanding full-sized mechanical gaming keyboard. Although it doesn't have dedicated macro keys like the Corsair K95 RGB PLATINUM XT, most people should be happy with it. It's also available in a wide variety of switches, more so than some other gaming keyboards we've tested, like the HyperX Alloy Origins. Also see our recommendations for the best gaming keyboards, the best mechanical keyboards, and the best RGB keyboards.

Corsair K68 RGB

The Corsair K70 RGB MK.2 is better overall than the Corsair K68 RGB, but the two keyboards are very similar. The only differences are that the K70 has an aluminum plate on top, it's available in more switches, and it has on-board memory.

Corsair K95 RGB PLATINUM XT

The Corsair K95 RGB PLATINUM XT and the Corsair K70 RGB MK.2 are very similar, but the K95 is better for gaming mainly because it has dedicated macro keys. The K95 is also better built and offers better typing quality. However, the K70 is available in more types of switches.

Razer BlackWidow Elite

The Razer BlackWidow Elite is better overall than the Corsair K70 RGB MK.2. It's a better-built keyboard with a comfortable wrist rest, and the Razer Orange switches we tested offer a better typing quality. On the other hand, Corsair's iCUE software is available on macOS, while Razer's Synapse 3 isn't.

SteelSeries Apex 7 TKL

The SteelSeries Apex 7 TKL is better overall than the Corsair K70 RGB MK.2. The SteelSeries is available as both a full-sized and TKL keyboard, it's better-built, and the SteelSeries Brown switches we tested are lighter to press than the Cherry MX Brown switches we tested on the Corsair.

SteelSeries Apex Pro

The SteelSeries Apex Pro is better than the Corsair K70 RGB MK.2. The SteelSeries is a featured-packed keyboard that allows you to customize the pre-travel needed on a per-key basis, and at its minimum setting, it offers a really quick gaming experience. However, the Corsair is available in a wide variety of switches, so you can get the ones you feel most comfortable with.

HyperX Alloy Origins

The HyperX Alloy Origins is slightly better for gaming than the Corsair K70 RGB MK.2. The HyperX comes with proprietary linear switches and the Corsair is available in Cherry MX Speed and Red switches, so you can get linear switches with either. The HyperX has a better typing quality and it's better built, while Corsair's iCUE software is available on macOS.

Ducky Shine 7

The Ducky Shine 7 is slightly better than the Corsair K70 RGB MK.2. The Ducky is much better built, the typing quality is significantly better, and it's available in more types of Cherry MX switches. However, the Corsair comes with a wrist rest and the iCUE software is available on macOS.

Das Keyboard Model S Professional

The Corsair K780 RGB MK.2 is a better keyboard than the Das Keyboard Model S Professional. The Corsair comes with a detachable wrist rest, has full RGB backlighting, and software for customization. That said, the Das Keyboard has a Windows key lock.
