This keyboard uses Corsair’s iCUE configuration software. This software is easy to use but somewhat clunky and not particularly intuitive. It lets you customize various expected settings, including key assignments, custom macros, lock key behavior, and RGB backlighting. Note that you have full access to certain RGB lighting effects when using this wired keyboard but more limited access to certain RGB effects when using the keyboard wirelessly.

You can save custom settings, including key assignment and RGB settings, to onboard memory. Saving to the onboard memory means you don’t need to have the software running at all times in the background, and you can carry over your settings to other computers without the software installed.

It’s worth keeping in mind that iCUE, much like the software options from other major manufacturers, receives widespread criticism from some users online as it requires frequent updates and can take up disproportionate system resources. This software may be frustrating to use if you prefer more lightweight software options or no software at all.

Note: Corsair indicates that certain SKUs of the CORSAIR K65 PLUS distributed within the Asian market aren’t compatible with Corsair’s iCUE software. For more details about this issue and a list of all affected SKUs, see Corsair’s website here.
