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, but the edges of the aluminum plate on top feel sharp, which could be annoying.

Our Verdict

8.4
Gaming 

The Corsair K70 RGB MK.2 is an outstanding gaming keyboard. Every key is macro-programmable, and you can customize the RGB backlighting on a per-key basis. It's available in a few different switches, but our unit has Cherry MX Brown switches that have minimal pre-travel distance and are fairly light to press.

Pros
  • Available in a few different Cherry MX switches.
  • All keys are macro programmable.
  • Full RGB backlighting with individually-lit keys.
Cons
  • Aluminum edges of the top plate feel sharp.
6.9
Office 

The Corsair K70 RGB MK.2 is good for office use. It comes with a detachable wrist rest and has an incline setting. You can get it with the Cherry MX switches you prefer, the keys are stable, and overall, it has a great typing quality. On the downside, the spacing between the keys might take some time to get used to.

Pros
  • Available in a few different Cherry MX switches.
  • Wrist rest helps with fatigue.
  • Great typing quality.
Cons
  • Spacebar feels wobbly.
  • Aluminum edges of the top plate feel sharp.
0.9
Mobile/Tablet 

The Corsair K70 RGB MK.2 isn't designed to be used wirelessly.

7.5
Programming 

The Corsair K70 RGB MK.2 is very good for programming. You can set macros to any key and change the RGB backlighting on a per-key basis. The typing quality with the Cherry MX Brown switches we reviewed is great, but you can get the switches you prefer. It has acceptable ergonomics as it has a wrist rest and an incline setting. Sadly, the dedicated software isn't available on Linux.

Pros
  • Available in a few different Cherry MX switches.
  • All keys are macro programmable.
  • Full RGB backlighting with individually-lit keys.
Cons
  • Software not available on Linux.
  • Aluminum edges of the top plate feel sharp.
4.0
Entertainment / HTPC 

The Corsair K70 RGB MK.2 is inadequate for use with home theater PCs. It's a wired-only keyboard, so you need to run a cable running from the couch to the computer, which isn't ideal if you have kids or pets. Additionally, you need a separate mouse because there's no trackpad.

Pros
  • Available in a few different Cherry MX switches.
  • Full RGB backlighting with individually-lit keys.
Cons
  • Aluminum edges of the top plate feel sharp.
  • Wired-only
  • No trackpad.

    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

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

    Popular Keyboard Comparisons

    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 K100 RGB

    The Corsair K100 RGB is better than the Corsair K70 RGB MK.2 for gaming, mainly due to its lower latency. Also, the K100 has dedicated macro keys, making it a great option for MMOs. The K100 is available with two types of linear switches, while the K70 is available in a variety of Cherry MX switches, so you can get the ones you prefer. The K100 has a multi-function wheel, and the included wrist rest is more comfortable.

    Corsair K60 RGB PRO Low Profile

    Overall, the Corsair K70 RGB MK.2 is much better than the Corsair K60 RGB PRO Low Profile, although it's mainly due to its superior typing quality. The Cherry MX Brown switches on our K70 provide tactile feedback, and their higher pre-travel distance lead to fewer typos, as the low profile switches on the K60 can be overly sensitive. However, the K60 has a better build quality, and its low profile might be more comfortable to type on for some.

    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.

    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.

    The Corsair K70 RGB MK.2 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. If you want a smaller version, there's also the Corsair K70 RGB TKL available.

    Build Quality
    Keycap MaterialABS

    Great 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're interested in a similar Corsair gaming keyboard but with PBT keycaps, check out the Corsair K70 RGB PRO. Or, for a newer model in the same lineup, check out the Corsair K70 CORE, which introduces pre-lubed switches and has layers of sound-dampening materials inside the case and spacebar.

    Acceptable ergonomics. The Corsair K70 RGB has one incline setting and 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 full RGB backlighting with individually-lit keys, and you can customize the colors on a per-key basis through the dedicated software. You can also cycle through three brightness settings directly on the keyboard with the 'Brightness' key on the top left. Note that the Windows Key Lock isn't lit up in the picture, but it lights up when you press it.

    Backlight Clarity

    Overall, this keyboard has outstanding backlight clarity that's very bright and clear. The legends on virtually all keys are extremely easy to read, except for the Caps Lock key, which has some visible obstructions and isn't quite as legible as the other keycap legends.

    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.

    19.0 mm (0.748")

    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.

    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.

    The Corsair iCUE software offers outstanding customization features. You can set macros to any key and customize the RGB lighting on a per-key basis. The keyboard has onboard memory for up to three profiles, and you can save as many profiles as you like in the software. Every time you make changes to a profile, you have to import a new file onto the board and overwrite the current onboard file.
