Question about Corsair Ml120 Pro RGB 3s

No, but it does have Corsair Link, Corsair's proprietary protocol. Unfortunately, the two cannot be synchronised with each other. There are some open-source solutions that try to do this, but I have never tried them myself. You can either set the same colour for both, or try to create an appealing colour image in some other way.

how do you configure the colour via corsair link? and how do you read the corsair power supply data?
thx
