Having used a variety of gaming keyboards, most recently the Logitech G213 which kept failing on me, I decided to go for a premium gaming keyboard from one of the top makers. I already have a lot of Corsair peripherals including the HS70 Wireless headset and several Corsair cases into which I build my gaming PC.
This is my first mechanical keyboard since working with IBM 5250 terminals 20 years ago. I wanted the feel and accuracy of a mechanical keyboard, but not the click noise that went with it. Cherry MX switches seemed ideal as they do not click yet are still mechanical.
Cherry Red switches are linear which means they have a constant motion. Brown and Blue have a tactile feel as they actuate and the blue switch also has a click. Cherry MX switches are good for gaming as they are quiet, quick and accurate. Brown is more suitable to typing as you get the actuation feedback.
Strait out the box you can feel the weight of this keyboard - its not lightweight coming in at 1.4 kg! Nonetheless this feels a very solid and quality product.
This is a wired keyboard with 105 keys, per-key individual RGB back lighting and an IP32 rating meaning it should survive that coffee spill.
First impressions of the keyboard are that the keys feel very slick. They have a much lighter actuation that I'm used to but similar to the keyboard on my Surface Book except with greater travel. There is no noise when typing unless you are heavy and the key cap touches the base. Having little feedback feels a little weird at first but I soon got used to the feel.
The keyboard has a nice detachable wrist rest which is a little plasticy feel but solid, and the keyboard can be angled up using two feet on the back of the base. One thing I did notice is that the feet are not rubberised, so when you flip them down you lose the rubber grip on the base of the keyboard. There are rubber grips on the front and the wrist rest which provide some grip but I found that the back ones provide the best level of grip.
Out the box the keyboard fires up with a radial sweeping rainbow effect, which may be too much for someone not wanting to install the iCUE software. There is a backlight key along the top which toggles different lighting intensity and to turn lighting off but as yet I've not found a way to have a static colour without installing iCUE.
The top num pad area features keys to adjust the brightness of the lighting, and to turn it off, a Windows Lock key and the usual media control buttons. These can be also all be rebound or assigned to macros functions like all the other keys. About the only thing you cant customise is the colour of the lighting and lock buttons or the colour of the caps lock, scroll lock and num lock indicators.
One of the large criticisms of this keyboard in other online reviews is that the keys are a grease magnet and I half agree. The keys are a very fine matt effect which does show up grease if you look for it but if you don't notice it unless you are specifically looking for it. I would not say that the keys are any more or less greasy than any other keyboard, its just the way it looks in certain light.
The Corsair iCUE software has just been updated to version 4, and in my opinion version 3 was better. The new version feels very clunky and not everything works as the previous version did, especially creating profiles and assigning key mapping or macros. It's kinda counterintuitive to assign them and it seems a bit random if it will save or not. Version 4 is also double the size of the previous version and comes in at 740MB (for a keyboard and mouse driver)
Software problems aside, the Corsair K68 is a pleasure to type and game with, I look forward to many hours of gaming and I'm sure I'll do a lot of writing and coding with ease as well. As I discover new features or problems I'll be updating this page but so far after a week of usage I have nothing but positive praise for this keyboard.
