While building this PC i had to make a few changes on the way, because RGB doesnt have a Universal Language yet, which really sucks, and i didnt know at the time of planning....
What i mean by this, is for example WiFi is WiFi where ever you go your phone/Laptop etc will connect no problem, its esay...
RGB is NOT like that and each company has its own "language" so if you mix Manufactures it is most likely NOT going to work.
Now for me Corsair iCue Software is by far the best software (in my opinion), as it gives you so much control....
Soooo i needed some special cables to convert some connectors to connect to Corsairs Commander Pro.
PirateDog Helped me out a lot here, he advised and made these cables:-
https://www.facebook.com/PirateDogTech/ - Hes USA based.
He also made a great post on how to make them if you want to try do it yourself.

to Order UK parts to make cables (but with postage it costs a lot, so not worth it unless you want to learn or are making lots):-

This site is also useful:-
https://www.moddiy.com/pages/Our-Guarantees.html (the 3.0 Splitter cable i bought didnt work but they gave a full refund, a long time after as well).

1x Corsair Lighting Channel Splitter £10
2x Corsair RGB to Aura/Mystic Light A-RGB Adapter £18
2x Corsair RGB Fan Hub to Strip/Lighting Channel Adapter £15
1x A-RGB 3 way Splitter £10.37 (Amazon)
