Hey,
I bought some of the Riing Quad last week.
From my experience with these:
For the power connector, you mean the cable from your controller with the Molex connection?
It worked for me, but they can be a bit tricky to connect, just make sure they are fully in. If it still gives you trouble, do you have some other TT controller that you can use to check if the problem comes from the cable itself?
Regarding the software, I´ll be painfully honest, It Su***, it´s really bad, on my side every single time I plug some audio the software crashes.
There seems to be no communication from TT RGB PLUS and NEON Maker.
I'll copy you the answer I received from Thermatake Support :
So there you go, they just suggest to roll back to previous version. it´s a bit better, but it doesn´t really fix anything.
So the best we can hope for is for TT to release a new software corrected with all these bugs.
Good luck
