Backlighting

The backlighting of the Raptor K40 is by far its most notable feature. There are many illuminated keyboards available today but you are typically stuck with a single color, depending on which product you purchase. The Raptor K40 has multiple LED lights installed, allowing it to change colors and even mix colors. Corsair claims that there are 16.8 million possible colors and the software truly allows for 16.58 million combinations; however, this reminded us of the following popular picture:

Although this picture is wrong in a number of ways, it depicts a simple truth: the number that a human can differentiate from one side of the visible wavelength to the other is between five and twenty colors. Females can usually differentiate more colors than males, although not to the level that the above picture depicts. The keyboard does allow you to select from millions of combinations, but most people will never care to choose a color outside the eight basic color settings provided by the software.

Although the ability to change the color of the backlighting is definitely nice, having >16 million colors to choose from is quite a bit of an overstatement. In addition, we should mention that you cannot program the color of individual keys. By changing the color in the software, the backlighting of the entire keyboard is changed. Per-key programming (both lighting and function) is a feature that Corsair will introduce in their new MX RGB mechanical keyboards, which are planned for a release in mid-2014.

Final Words

The Raptor K40 is an interesting product, with Corsair trying to bridge the gap between typical keyboards and expensive high-performance mechanical keyboards. True enough, the Raptor K40 is a very good product and with many notable features, and some users will even prefer good rubber dome keys to mechanical switches. Corsair also provides useful items like dedicated multimedia keys, the six programmable macro "G keys", and the on-board profile storage memory.

However, the most notable feature of the Raptor K40 by far is the customizable backlighting, offering the ability to select virtually any color of the visible spectrum that you want. It may be limited to a single color for the entire board at a given time, but the ability to change the color of the backlighting is somewhat unique (though several laptops have had this ability for years, e.g. Alienware, MSI, and Clevo all have RGB backlit keyboards). We could say that the Raptor K40 is the precursor, a portent of sorts, of the upcoming Cherry MX RGB keyboards that Corsair is currently working on.

As far as quality goes, our feelings are mixed. On one hand, the Raptor K40 is a well made keyboard. Even though the rubber dome keys are lacking in terms of texture, they are firm and consistent across the entire board. There was no discernable wobble in the keys and the larger keys retain their linearity even when pressed near their edges. On the other hand, if you have ever owned or seen a Vengeance K60/K70, the Raptor K40 feels like a cheap imitation. It's not that the Raptor K40 is bad; it is better than the average keyboard but it just cannot compare to the feel and quality of the Vengeance series.

Of course, the Vengeance series keyboards are significantly more expensive, but with a retail price of $79.99 the Raptor K40 is really pushing the limites of "value for money". The Vengeance K70 retails for $129.99, and $50 is a substantial difference; however, a mechanical keyboard with an aluminum frame is on an entirely different level. That said, quite a few gamers tend to prefer non-mechanical switches, whereas typists (like most of our staff of writers) would much rather use a mechanical keyboard. Or if you really want to live on the edge, you could try making the switch to an ergonomic mechanical keyboard, but that's not a step — or a purchase — to be taken lightly.

In summary, we would recommend the Raptor K40 to advanced users and gamers who want a "better-than-average" keyboard. If you've never used — or do not care for — mechanical key switches, the Raptor K40 is a good alternative. You also get RGB backlighting, which we won't see with Cherry MX switches for at least a few more months. However, if you are the kind of person that wants a keyboard "for life" and you're not afraid of pushing the budget a little, we strongly recommend spending more for a premium product with mechanical key switches, as the difference in terms of feel and quality is rather substantial.

    Apple's wired desktop keyboard uses the same keys as their laptops, but with a full layout (num pad, full size arrows, pg up/pg down keys). I prefer their older keyboards (and Thinkpad keyboards), but this one's not bad. The aluminum base also means it types more firmly than many keyboards with a plastic base.

    Hope this helps.

    I concur on the Apple keyboards, although you might want to look at getting a second hand one, as the prices new are hilariously high (at least in the UK).

    I've been using a 2008 Macbook as my daily hack for a few years now and I'm completely at ease with the layout and key depth - it's a very nice mix.

    I got myself an MS natural keyboard for my desktop, which is nice, but I've found that I take a bit of time to get used to it again after a day at work (dealing with other keyboards - I'm a techy), whereas with the Macbook I can just drop straight back in at full speed; so there's clearly something about a flat/straight layout that my hands like, even if my wrists will no doubt complain about it in a few more years time!

    Wonder how it compares to my old IBM PS/2 101 Keyboard. Its from the 80's and still works. Reply

    I reviewed the K60 and it was the best keyboard I've ever used. No missed keystrokes at all, ever. Reply

    Sure would be nice if someone would make a quality keyboard like this in an ergonomic form factor Reply

    Am I the only person who finds it odd that on the design of the board itself it appears as though the keys are hovering above the plane?? You know typically most keyboards mechanical or not that I have seen typically have the keys semi recessed so you don't have the full height of the individual keys exposed. Maybe I am just bonkers who knows, it does look like it would make cleaning easier though. Reply

    Other than their low-end Raptor LK1, this is Corsair's design standard for all of their keyboards.
    It's actually counter-productive for the backlighting.
    The lighting that comes from underneath each key overpowers what comes through each key, making it less useful, since the keys don't stand out.

    Acer did something similar with their keyboards a few years back, and then stopped doing it, because it was just *awful* to type on.

    This one looks to be a rather different (and rather better) animal.

    But those Acer 'floating island' keyboards - oh, the horror, the wobby, inaccurate horror.

    Since the stems for mechanical keys are more sturdy this behaves entirely different than those Acer keyboards, it's no different than a regular mechanical tbh, metal plate's in the same place (maybe just raised) and the sides are gone. It's a really nice feature IMO, I'm surprised it hasn't been copied, I don't even mind the splash out look of the backlight. Reply

    "That said, quite a few gamers tend to prefer non-mechanical switches"

    Most gamers have never tried a mechanical keyboard.
