Hi there! As the title says I'm on my third RMA, I own a cooler master PSU,
On every startup. it makes this grunting noise of sorts ( will attach an audio clip) and vibrates too.
It now also happens, occasionally on normal operation.
I desperately want to know if this is normal and safe, I'm sick of this.
Please check out the link, it happens after I press to start button, at around 0:03 seconds.
Thank you!
