I’ve tried with a GTX 780 and now a 1070 Ti with no difference. Unfortunately I don’t have another PC to try the PSU in, nor another PSU to try in my PC. Regarding coil whine vs buzzing, which do you think it sounds like in the video? I’ve done multiple recordings like that, to try and pinpoint which component is causing the noise and it’s definitely coming from the PSU. I’ve read a few other threads with similar noises. I thought it was just a noise I’d have to live with, but I’m concerned now that my PC randomly shut off.
