Corsair K90 Review

This keyboard is aimed at enthusiasts who love their macros. Personally I just love mechanical keyboards and would never go back to a membrane board after owning a Razer BlackWidow.

Build Quality

The keyboard is not made all from aluminium, but feels very sturdy due to the brushed aluminium fascia plate on the top of the board.

It comes with a very hard but soft-to-touch wrist rest that has a high quality feel to it. The rest is held in by two clips and two thumbscrews on the underside of the board.

It weighs a considerable amount for a keyboard but roughly the same weight as other mechanical keyboards out there.

Aesthetics

The looks of this keyboard are amazing, especially in the dark with the backlighting on. Due to the keys being raised reasonably high from board the lighting creates a glow effect, reflecting off the aluminium.

The bank of macro keys are to the left of the board and are seated a lot lower down to the rest of the keys. Corsair did this to prevent confusion while typing which is something that I faced with the BlackWidow as it's macro keys are right against the left column of keys which I would sometimes confuse myself with when trying to press Ctrl for example.

Key Switches

The switches on this board and Cherry MX Red which are basically non-tactile, non-clicky keys. They require 45g of force and actuate halfway through the travel (standard for the Cherry MX switches).

The key switches are what made me purchase this board over others, as this is the only gaming keyboard that uses MX Reds. The most common being Blacks then Blues.

The only difference between the Black and Red switches is the force needed to push the keys down, Reds needing 45g and Blacks needing 60g.

From not trying these keys before I can now say that, they are very comfortable to type on and even more comfortable to game on, and they sound nice.

Important: One thing to note about this keyboard however is that not all of the keys on this board are mechanical. This diagram shows the locations of the mechanical keys.

Keycaps

The keycaps are covered in a sort of matt texture coat with laser etched letters. This provides a nice grip after several hours of gaming and typing.

The only issue I have with them is that the letters themselves are quite small and the symbols on the numbers row are especially small and I do find myself taking longer to find the one I want compared to other keyboards.

Features

The keyboard comes with a bank of 18 macro keys subtly split up into three groups. There are also three different macro profiles which you can choose between with the M1, M2 and M3 keys located at the top left, giving 54 macro keys in total. You can record macros on-the-fly using the MR button on the keyboard or using the driver software provided by Corsair.

The keyboard has 3 levels of blue backlighting, a windows button lock key, media keys and a volume scroller control, which is very useful. The amount of times that a video is playing too loud and you need to turn it down quickly but you stuggle to find the keys quick enough, this key just makes it so easy to get the right level of volume nice and quickly.

It also has a USB 2.0 pass through located on the back right of the keyboard.

Backlighting

The backlighting on this keyboard is a nice electric blue with 3 different levels. The macro keys are lit by a white light, again to keep them apart from the main keyboard.

The backlighting is the only part of this keyboard that I feel lets it down. A lot of other mechanical keyboards have LEDs under each key to make each key well lit. The keys on this board are all lit at different levels, the main set of keys, arrow keys and the numpad are lit well. But the numbers row, f keys and the insert, home etc are not. The media keys are also illuminated.

Conclusion

(9 out of 10)

The K90 has impressed me in many areas. It feels great to type on and game on.

I would say that even though not every key is mechanical, it is still worth the money because it is cheaper than the other backlit mechanical keyboards available.

If your not as picky with the backlighting as I am, I would definitely recommend this keyboard over others.







 
Really good review mate. I really like the look of this keyboard and from your experiences seems like an awesome keyboard to type/play on. I love blue back lighting and I think it's the brightest I've seen on any keyboard thus far.

On videos the backlighting looked more amazing than it does in person. It is very bright in the centre but I think a keyboard such as the Razer Blackwidow Ultimate with an LED under each key would look brighter overall as each key would be evenly illuminated.

Ah, Ok. The keyboard's surface is brushed alu, right?
 
I just bought it !

The keyboard I use at the moment is becoming a bit uncomfortable to use, I also need to do quite some typing for School so I thought it was time to invest in a good mechanical keyboard.

Except for the escape and delete key not being mechanical the K90 ticks all my boxes.
 
Nothing will EVER beat the G15!

Nice review tho.

The Logitech G15 uses rubber dome keys. The K90 is in an entirely different league. Once you go mechanical you will never go back to a cheap rubber dome keyboard.

I really don't see why they didn't put all the keys mechanical, unless it saves money as the K90 is cheaper than other boards.
 
I need/want to try out the brown switches.

At the moment MX Blues I feel are faster to type on than MX Reds, but, Reds feel a lot more satisfying.

And Browns are a compromise between the two.

That's why I went with browns. I haven't tried out reds or blues though.

I did immediately type 10 words faster per minute with the new board. After a few weeks of use I'm at about 93 wpm. My previous keyboard was a cheap $10 basic USB keyboard.
 
After a while you respond to the tactile click quicker and more naturally as well, but the noise of the blues used to make me cautious of typing too loudly on my desk.

But as great as the tactile is for typing, for gaming it really doesn't feel nice, especially when double tapping for example.

I think the browns maybe a little different to the blues in this scenario though (so I've read anyway).

Well I own keyboards with both Cherry MX Blues and Browns. The force required to type on a browns are slightly less and there is a distinctly different tactile feel when pressing on the keys. It's hard to explain, but the best way to describe it is, Blues have a sharper feel, so it's hard just before the point of actuation, and drops of suddenly when you pass it. Cherry MX Browns feel softer, less force is required to get it past the actuation point and the force requirement after that doesn't drop off as suddenly as Blues, so it feels like a middle ground between Blue and Black.

Personally I prefer Browns or Blues for gaming, but that's a personal preference.

Good review by the way. And here's a diagram you might want to use.

Yeah I had read that Blues were a more of a precise tactile feel unlike the browns.

Have you tried Reds?

I wasn't going to use that one originally because it's the same as the Blacks but it looks a lot clearer and reinforces my points anyway so I've put it in

Thanks

Nice review, looking forward to using a mechanical keyboard - heard so much about mechanical>rubber dome that there's no way it can leave me disappointed.
 
A friend of mine has bought the K90, i haven't seen it but when i play games with it, i'll be able to see how it compares to my Rocatt Isku and decide if its worth getting it or not

My friend has a mechanical keyboard and i'm really tempted to buy one also...

Probably getting the K60.

I would never ever purchase a non-mechanical keyboard since getting my first last year.

You can't possibly be disappointed - as long as you get the switch which would suit you
