Hello, so it's been few months and my PSU is making grinding/electric/crackling noise like if electricity would make some noise. If it's possible I can add sound where you can maybe try to listen to it. And the fun part is that when I turn in power options high performance the sound is making that grinding/electric/crackling noise but when I turn on power saver or balanced its less making those noises. I'll probably add sound so that it's easier for you to detect my problem. Please help me the psu is used about 2years something like that. Here is the sound in sound cloud:
