Let’s face facts here. The K90 is basically
. The construction of the keyboard matches. The key layout matches. Hell, even the USB “pass-though” and cable match. The big question is where does “basically” end and the K90 begin?
Obviously, with any manufacturer you have products separated in lines according to cost and features. The K90 is considered the top feature packed input device that Corsair offers.
Conclusion: The Corsair Vengeance K90 gaming keyboard pairs a well-built gaming keyboard with a smorgasbord of customization, media controls and ergonomic features.
Pros: Great typing experience with springy mechanical switches. Adjustable backlight. 18 programmable macro keys. Built-in media controls and volume knob. On board memory. USB pass through. Detachable palm-rest.
Cons: Palm rest collects crumbs. Silicone dome switches used for some keys.
Conclusion: Performance in a keyboard is about being able to type and game without the peripheral holding the enthusiast back. Thankfully, the Corsair K90 performs admirably in both gaming and typing because the Cherry MX Red mechanical switches are great to type on and allow for extremely fast reaction times in games.
Pros: Mechanical Design, Linear force profile, Quiet design, Beautiful brushed aluminum exterior, Easy to use software, 20KRO instead of typical 6KRO for USB keyboards
Cons: The function keys and G-keys use rubber dome switches, Very expensive keyboard
Summary: The Corsair Vengeance V90 sells for a price of Rs. 7,280, which in our opinion is very expensive for a keyboard. Sure, it is a great performing keyboard, and is built really well, but this is something we’d recommend to someone who’s got a really massive budget for a gaming PC. As far as those looking for a good keyboard to type a lot on, but not game, we recommend looking at cheaper mechanical keyboard options on the market, which are usually a third of this price or...
Summary: The Corsair Vengeance K90 really is the complete package. You get all of the stand-out features of the best mechanical keyboards put into one great looking, solid package. The K90 can really do it all, FPS gaming, MMO gaming, multimedia, and typing, and it can do them well. The G-keys, the prominent feature of this keyboard, are simple to use and work extremely well.
Summary: The K90 raises the bar to new heights for gaming and mechanical keyboards alike, but could stand to lose its dome-switched function keys that greatly diminish the backlighting and feel. A driver and firmware update couldn't hurt either.
Pros: Individually-backlit typewriter keys, Cherry MX mechanical keyswitches, 18 macro keys with 3 shift states, Dedicated media controls, Smooth volume roller, Full wrist rest included, Windows key lockout, Standard 104-key layout, Rear-mounted USB 2.0 port
Cons: Membrane dome-switched function keys, Current firmware results in occasional repeating key, Backlight for function keys is very dim, USB port is single-port passthrough, Lacks the reverse tilt of the K60, Only available with Cherry MX Red keyswitches, Only available with blue LEDs
Summary: The Vengeance K90 is a sturdy keyboard that catches the eye with its aluminum chassis and blue lighting, a rare detail among mechanical keyboards. It features a high-precision response and more macro keys than the user will ever need (the pad feels a little overcrowded). You can easily clean the board because the keys are not embedded into it. The configuration program is simple yet powerful, and it can control the K90’s brother mouse, the M90.
Conclusion: After heavy usage over a period of two weeks on the Corsair K90, the performance and feel of the keys were definitely outclassing preferred keyboards using even more expensive non-linear Cherry switches. It appears that a natural adaptation is to not press the keys all the way down. Where this practice really excelled was in gaming (when making precision movements utilizing the keyboard was tantamount).
