PSU Noise Help

I have recently set out to build a PC. Everything has gone fine, but had serious problems sourcing a PSU. So I opted to buy a second-hand PSU off of eBay. I made sure to buy a PSU that was endorsed by PSU tier list out on the net. I seem to have this problem (see sound file attached) during the first 20 mins the sound is very audible and after you can't hear it unless you hold your ear close to the PSU. At first I thought it was feedback, and thought the motherboard was maybe the issue but now I'm quite sure the noise is coming from the PSU. Can you advise troubleshooting steps or whether I should be concerned at this? Just weighing up does it need returning or is it normal. Hearing PSU whine videos on YouTube it doesn't quite sound like that.

this could be caused by your drives, otherwise It's coil whine, common on some PSUs

PSA: No, I didn't waste all that money on computers, (except the main one) my server cost $40, the intel NUC was my old PC (although then it had 8GB of ram, I gave the bigger stick of ram to a person who really needed it), my laptop is used and the second PC is really cheap.

I like tinkering with computers and have a personal hatred towards phones and everything they represent (I daily drive an iPhone 7, or a 6, depends on which one works that day)

Do I need to be concerned if it is coil whine, only lasting audibly for 30 mins?
