This fairly common power supply has a very silly flaw involving the choice of assembly hardware. It also has what I would describe as just-acceptable separation of tracks with no anti-tracking slots.
These power supplies are the type normally seen lying loose in shop windows connected to badly installed LED tape and with their open live terminals perilously close to random metal junk in the vicinity and the aluminium window frame.
The hot diode issue is why I always recommend under-running these power supplies for a much longer lifespan.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
