Corsair K70 RGB Pro review: an advanced mechanical gaming keyboard

Ergonomics

With the K70 RGB Pro, Corsair anchors itself in the codes for its range of keyboards game, but we feel that the design has been updated with a slightly more modern aesthetic. The keyboard is more sober – which is not uncomfortable for us – and completely matte black. It is mainly made of plastic, but the chassis is covered with a brushed aluminum plate, which gives it good rigidity. Although it does not have dedicated macro keys on the side, it is still quite impressive on a desktop with overall dimensions of 44.4 x 16.6 x 4 cm. Its wrist rest adds an additional 8.2 cm in width, which is not insignificant.

This remains important because it allows you to raise your hands in front of the resulting height of the keys. It is quite comfortable and its rubber coating is soft. However, it is very stiff and we personally prefer the more padded wrist rests. It is also magnetized, which is really convenient to put it on or detach it from the frame, without complicating the work with clips.

All in all, this keyboard is very well built and the finishes are there. We find the keys without edges, which do not completely enclose the mechanical contacts that let the light from the backlight pass through. On this Pro model, the keys are slightly grainy and grip the fingers perfectly. They are also well stabilized and made of double shot PBT (double injection), a molding process that gives them a much longer life than conventional ABS plastic. The symbols should therefore not disappear immediately.

At the top of the keyboard we find in the upper left corner the three keys that allow you to change the profile of the backlight, to change its brightness (on six levels) and block the Windows key so as not to activate it in full session of the game In the middle we discover the Corsair logo and the various luminous pictograms that show which keys are activated (Shift, Mute, Windows key deactivated, etc.). Finally, the right part is reserved for dedicated multimedia keys, very convenient when you want to listen to music. The volume adjustment wheel is still useful, and its metal construction makes it particularly solid and fluid.

This K70 does not have dedicated macro keys, which some may regret. The rest of the keys are otherwise very classic, leaving the functions F1 to F12 blank to set the shortcuts of your choice in the iCue home software. This also makes it possible to control all the backlight with a wealth of lighting effects and an infinity of color combinations, or even to save different profiles. Alas, we had to start the software every time the computer started in order for our pre-recorded profile to start, otherwise the default lighting remained in place.

Another interesting point on the K70 RGB Pro, the braided USB-C to USB-A cable is now detachable, allowing you to replace it in case of a problem and move the keyboard without having to unplug everything. Next to it is another originality of this Pro model: an activation button in “tournament” mode, which offers to block personal macros in accordance with the rules applicable in official competition, and to activate static lighting so as not to become bothered by light effects. This mode seems anecdotal to us, especially since it will be reserved for a handful of players.

Finally, there are gutters under the chassis that allow the USB cable to be pushed to bring it out to the desired side, as well as non-slip pads to hold the keyboard in place. Retractable and adjustable feet on two levels are also present to raise the back of the keyboard if necessary.

The feet can be pulled in and the cable can slide down into a gutter.

Our test model has Cherry MX Speed ​​switches, excellent shifts linear, offering unmatched responsiveness with an actuation point of 1.2 mm for a total stroke of 4 mm. It is therefore the fastest version of the K70 RGB Pro, but two others are also marketed: one with the Cherry MX Red and their 2mm hotspot found on many keyboards game ; another version with Cherry MX Brown, similar models but tactile (we notice when the key reaches its activation point). We still appreciate that the choice is given to the user, even if fans of blue switch clicky will be disappointed to see them to absent subscribers.

The Cherry MX Speeds are perfectly integrated here, and the keyboard offers a very lively rebound, obviously suitable for nervous video games such as FPS. Be careful when it comes to writing text, responsiveness can be confusing and it will take a while to get used to. Initially, this can lead to many typos. These switches are guaranteed for 100 million activations, ie an excellent service life.

If the keyboard is generally free of defects, we can make a serious criticism of it regarding its honestly marked resonance. With each keystroke you will hear large “boing” of metal springs, which is the privilege of many keyboards game, but here resolutely uncomfortable to the ear – only headphones will be able to relieve us of this nuisance. At this price, we would like Corsair to work to limit this resonance, e.g. by using soothing foam.

The keyboard incorporates Corsair’s own Axon technology, which gives it a monster polling rate of 8000 Hz when most models close at 1000 Hz. distinguishes between these two speeds. Finally, of course, it has NKRO (N-Key Rollover), which allows you to press as many keys as you want at the same time, as wellanti ghosting to avoid any misinterpretation.

How does grading work?

The K70 RGB Pro benefits from excellent build quality and many interesting elements, especially a practical dedicated multimedia shutter, a complete and well-transferred key-by-key backlight, double-injected PBT keys and a detachable braided cable in addition to a magnetic palm rest . In addition, its responsiveness is impressive, which is perfect for nervous video game use, but we regret a strong resonance of the chassis, which can quickly weigh on the ears.
