Corsair K95 RGB Platinum Keyboard Review

Testing & Results

Testing Methodology

The best way to test a keyboard is to simply use it. The K95 RGB Platinum was tested for an overall period of 30 hours with Diablo III, Tom Clancy’s The Division, Photoshop CS6, and various typing tasks including this review.

Corsair claims to set itself apart when it comes to anti-ghosting and full key rollover. The term “ghosted” refers to the keystrokes that are not detected and then drop off (for example, when someone presses D-C-U and only sees D-C, the U has been ghosted). While anti-ghosting is present in most gaming keyboards, it is often restricted to a certain number of keys or sections of keys. Popular sections of limited anti-ghosting may include the WASD part of the keyboard as it incorporates the keys that are the most common to use for first-person shooter games.

Corsair claims:

“The K95 RGB PLATINUM keyboard features a 100% anti-ghosting matrix with full key rollover. This ensures that every keystroke will be recognized accurately by the computer, even when simultaneous combinations are inputted by the user.”

Now we’ll see how accurate that is.

Test System

  • Motherboard: MSI X99A SLI PLUS LGA 2011-v3 Intel X99
  • System Memory: HyperX Savage 64GB (8x8GB)
  • Processor: Intel Core i7-5930K Haswell-E 6-Core 3.5 GHz LGA 2011-v3
  • Audio: On-board
  • Video: 2 x XFX Double Dissipation R9-290X (4GB) (Crossfired) (1 card after-market water cooled)
  • PSU: Seasonic 1200W Platinum
  • Monitor: Dell UltraSharp U2412M IPS 24″ x 3 @ 5760×1200
  • Operating System: Windows 10 Pro (64-bit)



As you can see from the results above, Corsair’s claim for full key rollover is accurate, at least as accurate as I can test since I can’t physically press all the keys at the same time, but you get the idea. I can, however, press enough keys to know that you won’t have a large enough combo for the full key rollover to matter.

    Great review! I have this exact same keyboard and enjoy it. I would love to see a comparison review of this keyboard but with the cherry brown switches instead of the speed switches. The speed switches are extremely sensitive but I can see how they got their name and unique feel. I’m really curious at the difference.

      The difference would only be evident in the stroke, as the Cherry MX Speed and Brown switches share the same 45g actuation force. Speed has a 1.2mm actuation distance, compared to 2.0mm for Brown. That 0.8mm difference appears noteworthy if you compare the numbers, but is not terribly significant in real-world use.
