My old power supply stopped working outright, no spark or anything, so I replaced it with a new Cooler Master MWE 750 Bronze V2 and everything works as should be. Only when I am either gaming or streaming my pc I hear a high pitched noise. I tried my best to record it and isolate the sound. it's the included mp3 file. can anyone help me identify the noise and what to do about it?

IIRC that PSU is actually known for having coil whine, and it's not uncommon to have coil whine coming from a PSU. Only real way to fix it is get a new PSU or a more silence-optimized case to block the noise from the PSU.
