I recently bought the Sonnet Breakaway Box 750ex for my laptop. Some of the time when I plug it in, the eGPU actually turns on and works properly but most of the time, the PSU and board make faint clicking sounds (In the video below, I plugged in a louder 300W PSU to record the clicking. Both PSUs work ftr). I know that PSU keeps turning on and off again rapidly, but beyond that I don't know what is going on. Any ideas on what is happening and how to stop this?
