Corsair K70 LUX RGB Keyboard Review

K70 LUX RGB Overview

Corsair offers six variants of the aluminum-bodied K70 RGB keyboard: the Rapidfire version we’ve previously reviewed; the LUX version with Cherry MX Red, Brown, or Blue switches; and the slightly more expensive non-LUX version with MX Red or Brown switches. The non-LUX versions have internal processors and memory so that you can program lighting effects and macros that stay with the keyboard and can be used on other systems, while the LUX versions depend on Corsair’s CUE software to provide macro and lighting functionality. The front of any K70 is dominated by its frameless design and black anodized aluminum key plate.


The back of the keyboard contains only the product label and fold-out feet. Probably due to the very thick USB cable, there are no cable channels.


One interesting item is the addition of fold-out support feet at the front of the keyboard:


The thick, braided USB cable is permanently attached, and has the requisite gold plating on the USB connectors and braided sleeving on the cable itself. One cable is for the keyboard itself while the other cable is for the USB pass-through port on the back of the keyboard.


A selector switch on the back enables you to choose between 1, 2, 4, and 8ms reporting rates, as well as a “BIOS Mode”. Even the slowest 8ms reporting rate gives you 125 keystrokes per second, so the utility of this feature escapes me. “BIOS Mode” is required for the keyboard to operate on some older systems; however, this disables communication with the CUE software, so in this mode you’ll lose everything except the built-in static lighting pattern (all keys red except WASD and the arrow keys, which will be white).


At the upper right of the keyboard are the dedicated media keys, knurled metal volume control, mute switch, Windows lock key, and the lighting intensity key, which when pressed cycles through three lighting intensities plus off.


Accessories include the snap-on, rubberized wrist rest, some textured replacement key caps (with a plastic key cap puller) for FPS and MOBA gamers, and a couple of pamphlets. The wrist rest is a nice inclusion but I worry about the long-term durability of its snap-on connectors. No software or documentation is provided, but you can download a very complete manual and the Corsair Utility Software needed to fully utilize the keyboard from Corsair’s web site.


Let’s take a closer look at this keyboard in the next section.
