Right box goes KSHKWWWSHHZZZZ

Steinberg Hardware UR Series
#1

Greetings,

I don’t know if this is the right forum, but I have a UR824.

I had to switch out my graphiccard and my power supply unit. My boxes are KRK VXT8. Since some time now, I have this noise on the right box, especially when the cpu, the network or a hdd is working. It’s like KCCHSHWWWZZZZ, a really ugly noise. And now since I have switched the power supply unit (I went with 1000watt, maybe a mistake), the noise has become alot louder.

Does anyone know a way to stop this? It’s awful.

Thanks,
Ki

Edit: I have found about 5’000’000 entries to this problem on Google and didn’t understand the solutions. It’s something like groundloop?

It was the cable. Switched it out with one of the cables from the keyboard -> no more noises.
