    I have the silver + MX Blue and I love it. Much more when you looked at it in person compared to pictures and dedicated media keys are just what keyboards at this price point should have (instead of dopey Fn). The only thing I have to complain is the LEDs, they're dying very quickly.

    The first dead LED was about 2 weeks after I bought it. Fast forward 7 months later (today), 34 of the LEDs are dead (I counted it). Not a deal breaker for me (since LEDs are just extra), but a lot of people complain about this in their forums.

    So, I'd like to advise those who are interested in buying these models, if backlighting is important to you, be prepared to lose some (it may happen to you too). Early adopters of the upcoming MX RGB should probably consider this as well.

    Dead LEDs. I bought this keyboard for my wife in February 2014, and in light use, we have 6 dead LEDs.
    Don't throw away your receipt, you'll need it for RMA.

    I've had mine for a little over 9 months - keyboard stays lit 24x7 and I haven't lost a single LED yet.

    Great keyboard for doing a lot of typing.

    Had my first for ~16 months, no dead LEDs (fried during a storm, keys stopped pressing)
    My second is on ~10 months, no dead LEDs. I did however have to RMA the second once to get all my LEDs, the RMA'd was missing an LED while one flickered at low light.

    I think it's more of getting them dead than it is them going dead later. *k90 for reference.

    My K70 had about two dead LEDs - which I thought was because I once thumped it pretty hard in a fit of TF2-induced rage but now realize might have been part of a larger pattern - until it died completely, spontaneously all by itself.

    Woke up one morning months after first discovering the dead LEDs, PC had bluescreened overnight, having been running Folding@Home constantly. Oh well, I thought. Such is the overclocker's lot. However, keyboard would not respond anymore, no matter what. I realize this (keyboard dying) is probably what crashed the computer.

    I never bothered to try and return the keyboard, seeing as I thumped it (there's no visible damage at all - it's surprisingly solid despite the seemingly delicate-looking mechanical switches), but now I'm thinking maybe I should. *shrug* I have a K60 as reserve, which works okay now after the firmware flash. It every once in a blue moon burps out double keystrokes, but at least no longer produces those stuck buttons that were so annoying/dangerous, especially when typing and hitting backspace...

    Same here, for a period of about 7 months now, they are lit 24/7, not a single dead LED. It even fell off my desk once while the girlfriend was cleaning and it survived. The wooden floor has a little pit and scratch from the corner of the keyboard hitting it though. Reply

    RGB shouldn't have that problem. Reply

    I too had the same problem with the LED's on my 1st Corsair K70-- Cherry mxbrown with blue LED's. It was after a month that LED's started dying first it was 3 then the next day 7 and so on.. So i RMA'd it (which took more than a month to be replaced poor customer support really) and got the mxblue with red LED's variant and so far it's been holding out without a single dead LED.

    I believe there have been quality control problems with the blue LED variants because as what i have read in corsair forums most of the owners got dead LED's and the red LED owners are not complaining. and when i RMA'd my blue led the support people told me that blue LED's are no longer available which lead me to believe that Corsair is issuing a silent recall for the blue LED's just my theory i suppose.
  • Evilkoala13 - Friday, June 13, 2014 - link

    I think you're right about the blue LEDs having quality issues. I got the mx brown and blue LEDs version and some of the LEDs failed after 3 weeks. I RMAed it and got the replacement quickly. Then, the replacement started losing LEDs and I RMAed it again, but this time the mx brown with blue LEDs was no longer in stock. I kept checking every few weeks but it never came in. Last month I was informed that Corsair has discontinued the blue LEDs model and now is only shipping the reds. Corsair has been great with customer service though and is replacing my broken keyboard with the MX Brown and red LED model. Reply
  • dyc4ha - Monday, June 09, 2014 - link

    yup i love the keyboard, but 3 dead LEDs in within the first 2 months.. =/ Reply
  • Azethoth - Monday, June 09, 2014 - link

    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? Reply
  • Icehawk - Monday, June 09, 2014 - link

    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 Reply
  • Stuka87 - Monday, June 09, 2014 - link

    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. Reply
  • Antronman - Monday, June 09, 2014 - link

    Did you get the MX Blues, Browns, or Reds? Reply
  • 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.

    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). Reply
  • Antronman - Tuesday, June 10, 2014 - link

    You should've gotten a keyboard with MX Black, since those are rated for ~50 million clicks. Reply

    You can game on Linux. I dual boot between Windows 7 and Ubuntu and I want the RGB version of this keyboard. I play what games I can on Linux, the rest I play on Windows. I have the Corsair Vengeance 2100 headset and the M95 gaming mouse and they're both great, except the software that let's me program macros for the mouse and optimize the headset is Windows only. I don't think it's unreasonable to request that Corsair make their PC hardware work in Linux... or at least give the community open access so we can make it work ourselves. Reply
  • Black Obsidian - Tuesday, June 10, 2014 - link

    I own a Logitech G710+ (Cherry MX Brown), and although I *have* a Windows gaming PC, I actually use this keyboard at the office. That's where I do most of my typing, and thus most appreciate the tactile feedback of the mechanical switches. And I have the macro keys bound such that I can just spam all 6 of them in a row first thing in the morning and my whole dev environment launches. Reply
  • domboy - Tuesday, June 10, 2014 - link

    I also have a G710+ at work that I use with a Linux workstation. This keyboard apparently also used to have issues with Linux, but something in more recent distributions/kernels must have resolved the issues as I've had no trouble in the couple months I've had it. Just because it's marketed as a gaming keyboard doesn't mean it has to be used that way. Corsair needs to fix the issue. Reply
  • Impulses - Tuesday, June 17, 2014 - link

    It's not like any one feature makes it strictly a gaming keyboard... Shoot, I only use the backlight on my K90 when I'm coding late at night, and I only use the macro keys for stuff like Lightroom & PS shortcuts. Even the media keys and my choice of red switches aren't solely driven by gaming needs. I've actually thought about getting a more compact TKL for gaming so my mouse is closer but ehh, I like the K90 so much. Reply

    What's with the dual USB ports? Do they need the extra power for all the backlighting, or is it something else? Reply
  • basickler - Monday, June 09, 2014 - link

    There is a USB pass through on the keyboard. Hence the 2nd USB plug. Reply
  • ss284 - Monday, June 09, 2014 - link

    It's not a passthrough, It's for extra power. The keyboard generally works fine with one USB port, but I've had issues waking from sleep with only one USB plugged in. Reply
  • Stuka87 - Monday, June 09, 2014 - link

    The second USB port is for anti-ghosting. It has nothing to do with needing more power or having USB pass through. Reply
  • Stuka87 - Monday, June 09, 2014 - link

    Oh, and I should note that it needs both plugged in to function correctly. Same goes for other dual-USB keyboards. Reply
  • rocktober13 - Monday, June 09, 2014 - link

    I have this keyboard. I only have one USB plugged in and it works great. Also, it's plugged in to a dual output USB hub (so I can use it on 2 PCs) with no extra power. I am pretty sure the extra USB is just a pass through (which I don't use). Reply

    "Oh, and I should note that it needs both plugged in to function correctly."

    Oh and I should note that you are completely wrong.
  • localhostrulez - Saturday, June 14, 2014 - link

    And I will confirm that. The manual specifically says that one connector is a pass-through for the USB port and is optional. From what I've seen with mine, this seems to be the case. For that matter, I tried using the second cord as an extension cord for my phone and its wall power adapter. Worked just fine, AC charging mode used. Reply
  • Impulses - Tuesday, June 17, 2014 - link

    Pretty clever idea, if I wasn't using wireless Qi charging pads all over the place now I'd copy it. Reply
  • piiman - Saturday, June 14, 2014 - link

    Its a USB PASS THROUGH you don't even need to plug it in if you don't want to use the port.
    Its has ZIP to do with anti ghosting or power.
  • basickler - Monday, June 09, 2014 - link

    It's a pass through unless they're lying on the product page and it's a hub. There is a USB pass-through port on the back of the chassis which I use it to plug my mouse in.
    I bought this keyboard after looking around for a few months. After half a year with it I can say that I love this keyboard. The red led version doesn't have the LED burn out issue and it's built like a tank. And I never found myself using all the fancy controls of multimedia keyboards but I really do like the volume controls on this.
  • DanNeely - Monday, June 09, 2014 - link

    Normally putting a USB port or two on a keyboard is done without needing a second port on the computer by integrating a USB hub. Reply
  • profquatermass - Monday, June 09, 2014 - link

    These keyboards need 2 USB ports in order to handle the amount of key press traffic. Reply
  • piiman - Saturday, June 14, 2014 - link

    You are so wrong.
    1. Why do you think these keyboards have more "key press traffic"?
    2. You can type as fast as you like and you will never max a USB port band width with your slow human typing speed.
  • patrickjchase - Monday, June 09, 2014 - link

    A 1 msec polling period corresponds to 1 KHz, not 1 MHz as stated in the article. Given that human reaction times are on the order of 100 msec even the 1 msec interval is overkill. Reply
  • l8gravely - Monday, June 09, 2014 - link

    I've been quite happy with my "Code" keyboard from with the Cherry Clear. I got it because the back lighting was nice and even, it was Cherry MX Clears, and I could also get it in the TenKeyLess version with only 87 keys, since I don't use the numberpad at all. I've been very happy with it.

    My kids love it too, but miss the keypad when playing in minecraft, because they can't fly airplane mod which depends on the keypad. Oh well...

    I spent around $150 for each of my two keyboards. Not cheap at all, but to me well worth it if they last like I think they will.

    Wait, the K70 RGB launched? I don't see availability anywhere, including newegg and amazon. Reply
  • dragonsqrrl - Monday, June 09, 2014 - link

    ... okay, on the first page it says Corsair already launched the RGB versions, then on the second page it says they won't be available for a couple months? I'm guessing there's a mistake somewhere in there. Reply
  • Antronman - Monday, June 09, 2014 - link

    They've launched. They're just not in stock yet.

    A product launch means the product is finished, and ready to be shipped to stores.
  • dragonsqrrl - Monday, June 09, 2014 - link

    That just seems very strange to me. At least in my experience a product launch typically declares immediate availability or availability in the very near future, neither of which seems to be true in the case of these keyboards. This seems more like a paper launch to me than anything else. In any case, if what you've saying is true, that's one hell of a long shipping delay. Reply
  • Antronman - Monday, June 09, 2014 - link

    Yeah. But it's still worth it.
    The Steelseries APEX is just such a compromise. You sacrifice the amazingness of mechanical keys for RGB lighting.
    RGB + Mechanical? Awesome.
    LEDs inside the keywells to allow for less damage to LEDs.

    And then the RGB mice is also really nice.

    Warning - I had the K90, and while it was a great keyboard, I accidently knocked a beer onto mine. The beer (About 1/2 a 12oz beer) killed the keyboard. It didn't malfunction, it completely died and became a brick. So, if you are prone to spilling drinks on your keyboard, this may not be the one for you. Reply

    I have a K60, which is difficult to properly take apart in order to clean or recover from spills.
    I notice the K70 seems to have the same volume control design that is the sticking point on the K60 (one of the sides has to be carefully removed or it will break); is the K70 similarly hard to take apart?

    I have this keyboard for about three months now. Works great. I like the feel and I use it for gaming and everyday typing. Haven't had any LED issues. Came from a Logitech G15. Yea no G-keys, not a big deal, never used them anyways. Like the fact that the media keys actually integrate well with all of my media software. Am waiting for the RGB also. Reply
  • dorekk - Friday, June 20, 2014 - link

    I have this keyboard and I view the lack of software as a plus, not a minus. I like that I don't have to run any annoying software in the background to change the backlighting (this isn't mentioned in the review, but to do per-key backlighting you hold down the "gaming" mode button, then press any key to enable to disable its backlight, then hold down the button again). I have no need for macro keys, so it's nice to not need software. I have it in black with MX Reds and the typing feel is awesome and the backlights are fine so far. (I've had it for about a month.)

    I do kind of wish I had waited just a couple months so I could get the RGB version, but damn, $130 was already pretty extra 50 bucks just to have different colors is a little much!
  • sean_themighty - Wednesday, June 25, 2014 - link

    1. The black on black logo is a huge plus. It's the closest thing to no logo you can get.

    2. No additional software is a huge plus. I used to have a Razer keyboard that had mind-numbing additional software required to "unlock" features. No thanks.

    3. This is a dedicated gaming keyboard for me, and I primarily play first-person shooters, so the textured ASDF keys are fantastic. Also, the red switches are perfect too. I do prefer the blue switches for a general-use / typing machine, though.

    On another note, I'm surprised now much information the manual leaves out... like how to program your own unique key light schemes, or how to turn on lit key confirmation mode. I only even knew how they worked by stumbling upon others who had mentioned it.

    The arm rest that comes with the keyboard is flimsy. Unlike the keyboard itself, which has a sturdy metal body, the arm rest is made of plastic. The plastic tabs that hold it in place are poorly designed and break off easily. (An image is available at

    To make matters worse, Corsair refuses to replace the part under its warranty. Instead, they want $10, plus tax and shipping, to replace the armrest.
