I want to include my experience to help the community.

I recently had a power supply that died and I noticed some signs of it dying and wanted to include them here.

It started with an electrical whine whenever I would heat up the heat bed or the hot end by themselves. Once I would heat them together the whine would go away.

After this my power supply output a lot of noise when heating up and being used, kinda like the fan was on overload. Then today I attempted to print and the power supply made so much random noise that it was not bearable to use.

So I ordered another power supply (one of the potential knock offs of the Mean Well) from Amazon today. Thanks to one day shipping I have it installed and the noise difference is incredible!

Just be on the look out everyone, these potential knock offs don't last to long. I had my previous one for a year.
