Question RGB/Power supply issue

Hello everyone, I'm having an issue with the RGB in my case, but I'm starting to wonder if it's symptoms of a bigger problem.

I first noticed this problem when I bought some Thermaltake Riing plus fans for my case. I installed them and connected to a TT sync controller which I intended to use with ASUS Aura Sync. The fans were spinning just fine, but the RGB looked funky. One fan was partially lit with one LED flickering on and off until it just turned off completely. The 2nd one didn't turn on at all. After troubleshooting all over the internet, I assumed I might have just bought bad fans.

Just recently I got myself a Kraken X73 AIO. When I connected it, the pump wasn't working at all. I ended up connecting it to a different SATA power cable and the pump worked, but the LED on the AIO turned on for a brief second and then turned off completely and never came back on. I also connected three more riing plus fans to the radiator that are spinning just fine, but are having similar RGB problems. I've been troubleshooting the internet for hours and messing with the CAM software but I can't find a solution.

Could this be signs of a bad power supply? I have a thermaltake 850w power supply that has worked just fine for about 6 years up until now. Other than the RGB, I have not noticed any other signs that it could be bad. I'm wondering if it's the power supply because when I reconnected the AIO to a different Sata cable, it partially worked. It doesn't seem likely to me that both cables are bad. Especially because one of them is brand new.

Thank you all in advance for your time and expertise!

let me make a guess, i think its most likely the TT sync controller that is the problem.
as for your 2nd problem, did you connect the LED of your AIO to the TT sync as well?

The radiator fans are connected to the TT sync controller, but not the AIO itself. I tried experimenting by disconecting the controller, but I still had the same problem.

Another update: I had a RGB strip in my case that was working fine and suddenly, it's having the same problems as the rest of the RGB in my case. It was only connected to the power supply and the USB header.
