Can you record the sound? I’ve never heard of a power supply having any kind of noisemaker. It’s probably just electrical interference or coil whine or something, where the waveform happens to produce that periodic sound. (You might even look around and find a nearby device changing its power draw with the same periodicity.)
Those info sites aren’t built from bank records. They’re built from public records databases like voters, property, taxes, legal cases, and government actions, including stuff like just showing up to the city council to complain.
