So I am getting coil whine that sounds more like stock-footage electricity than the high pitched shit in the typical examples. When I get this, it coincides with one of my monitors flickering with white horizontal lines. I am using the Vga connector on my monitor to a DP on my GPU, which I know is a sin and I could replace it, but I think it could identify whether the source of my coil whine is from the GPU (MSI GTX 1080 Gaming X) or the PSU (EVGA 750BQ). I suspect the PSU. But maybe if one of you know that monitor outputs being affected means faulty GPU, that could help me identify it. Thanks!
