Mechanical keyboards are far from a new technology; they are decades old and some of the first mass produced personal computers came with mechanical keyboards back in the 1980's. However, due to their high production cost, they were soon replaced by keyboards other types of electronic switches that were considerably less expensive. Over the years however, the production cost of the mechanical key switches also came down, making them more and more affordable by the day. Today, PC users can find a good selection of mechanical keyboards from numerous manufacturers available at (generally) reasonable prices.

Today we will be having a look at the Vengeance K70 from Corsair, a full size keyboard designed for gaming. It is an upgrade of the popular Vengeance K60 and it is remains strikingly similar visually; however, aside from the various upgrades that we will discuss in this review, Corsair also offers the K70 in various color and switch combinations. In this review we will be looking at the black US layout version of the Vengeance K70, which features red backlighting and comes in three switch types (red, blue or brown), as well as in various layouts. Corsair recently launched the RGB LED backlit model at Computex, but that was not available when we started this review.

The Corsair Vengeance K70 Mechanical Gaming Keyboard

The first upgrade over the Vengeance K60 can be found in the bundled items. With the Vengeance K70, Corsair supplies a set of ten textured red keys (1-6, W, A, S, D—the standard gaming keys for FPS games) and a full-size wrist rest, where the older K60 only came with a small 5" wide wrist rest for your left hand while gaming.

Corsair supplied us with the three black US layout versions they produce, each featuring a different Cherry MX switch. The three keyboards are aesthetically the same and no one will be able to tell the difference between them before a keycap is removed. Once a keycap is removed or an experienced user presses a key, the difference between the Blue, Brown and Red switches become apparent. Corsair, at least for the time being, does not offer the Vengeance K70 with Cherry MX Black, Green or other switches.

Visually, the Vengeance K70 stands out from the crowd by following the same design that made the Vengeance K60/K90 popular. The keyboard is built on a brushed aluminum chassis, with the keys levitating over it rather than being embedded into it. Aesthetics are a subjective matter and some people like this design while others hate it. From a practical point of view however, this design is extremely helpful to those that like to keep their keyboards clean, as a simple blow can remove all debris from the surface of the keyboard. A primary aesthetic flaw however is the black company logo at the middle top part of the chassis. Although the logo looks very good on a silver keyboard, I feel it was a poor choice to keep the same logo on the black version of the Vengeance K70. A less important flaw are the screws that keep the motherboard together; most of them are behind keys and invisible, but a few are at places that are somewhat noticeable, such as beneath the Esc key.

Corsair installed multimedia control buttons and a volume knob at the upper right side of the keyboard. There are four keys for playback control (Play/Pause, Stop, Forward and Back) and a volume mute key next to the metallic volume knob. Three smaller keys can be found towards the top center of the Vengeance K70; one that controls the lighting, one that switches the backlight into the "gaming" mode, and one that renders the Windows keys inactive. Between these and the multimedia keys, there are three tiny white LED lights serving as the three standard key lock indicators (Caps Lock, Num Lock, Scroll Lock).

Although the installation of the textured red keys gives the Vengeance K70 a nice, aggressive gaming appearance, we found that these keys are more than just useless to any user that will not play a game using these specific keys. The keys are contoured, which gives them a nice feeling while gaming, but they feel terrible when doing anything else, especially typing. Therefore, unless you are planning to use the keyboard exclusively for playing games that are making use of these exact keys, replacing them each time you want to play a game feels like too much of a hassle.

Corsair installed a single USB 2.0 port at the top back side of the Vengeance K70. Right next to the USB port there is a switch that allows the user to change the polling rate. This function is not needed for any modern system but it increases the keyboard's compatibility with older motherboards and cheap KVM switches, which cannot operate properly when the polling rate is too high. The default polling rate of the Vengeance K70 is 1 ms (or 1 kHz). Beneath the keyboard are four feet for height adjustment, two at the rear and two at the front of the keyboard. Although stands at the rear of the keyboard are quite common, very few designs have the ability to adjust the tilt at the front.

    Are you sure the keys are in fact dead and that you did not just disable them? I have a K-95 and the keys can be individually lit / not lit. You may have tripped the on/off mode inadvertently?

    Have this keyboard, great build quality but even with o-rings beneath the keys it is pretty darn loud (and yes I know mechanicals are not going to be silent). My gripe with the K70 is the key spacing is just too tight and even 6mos later I find myself fat fingering. Tempts me to go back to my plain MS keyboard TBH

    You may want to try out a 2014 Razer Black Widow Ultimate Stealth. its the quietest mechanical keyboard I have ever used, but still has great key feel.
  • Antronman - Monday, June 9, 2014 - link

    Did you get the MX Blues, Browns, or Reds?
  • Icehawk - Tuesday, June 10, 2014 - link

    Mine are Reds.

    Thanks Stuka, I will have to see if TigerDirect stocks them so I can check in person - the key spacing on my Corsair drives me nuts, maybe this will be better spaced and quieter.

    I don't suppose you could officially bug them about compatibility with non-Windows OS, namely OS X and Linux? Since the keyboard is driverless you'd think it would just be plug-and-play, but apparently something with their design/firmware causes the caps lock, scroll lock, and num lock LEDs to not work or blink even with the keyboard's BIOS compatibility mode set when not using Windows. Everything else including the multimedia keys reportedly work, just not the lock indicator LEDs. I like that the K70 is a simple mechanical keyboard with multimedia keys and wrist pad, but I intend to use it in both OS X and Windows so I've held off because of the reported compatibility issues. I don't suppose they've fixed this with the MX RGB version?

    Why would you have a gaming computer that runs anything or than Windows?

    It's like having a V8 in your car, but only 1 exhaust pipe.

    Some people may have this keyboard with a dual-boot computer. Also its not like this keyboard can only be used for gaming.

    Why would you buy a gaming keyboard if you're not gaming with it?
  • localhostrulez - Tuesday, June 10, 2014 - link

    Hey, I just ordered a Corsair K70 mx blue, and I don't game. I did it because I liked the build quality, media buttons, and wanted an overall well built keyboard for typing. I type a lot, and am tired of disposable electronics (and I've managed to wear out quite a few rubber dome keyboards over the years).
