I woke up this morning.
When I turned my pc on, I noticed an unusual buzzing sound that would repeat every 2 seconds. It's loud in the sense that it will annoy you, although it is quite quiet.
I narrowed it down to the Psu.
I have a EVGA 500W 80 plus.
Whenever I turn it on vertically, the sound occurs.
Whenever I turn it on on its back, it doesn't occur.
Should I be concerned? I am actually really worried about this.
I only built this new pc in July last year.
