Well, the first thing you need to do is make a different recording, WITHOUT moving around making small noises and without any other background noises, because those make it impossible to pick anything out. Going off that recording I don't hear anything that sounds abnormal but you probably need to put the microphone near the PSU and just leave it there, do not move it around and do it when there is little outside traffic, people talking, kids, etc.
Based on this review the PSU has an above average noise profile anyhow, at all ranges, but it also has a fluid dynamic fan bearing which, while it will last a long longer than a sleeve bearing is also going to be a lot noisier. If the noise you are hearing is clearly not fan related then it might be coil whine as Aris also indicates in that review that it has poor efficiency under light loads which often tends to result in some units also have coil whine issues under those same conditions. Does it make this noise when it's under a decent or full load?
