Power Failures

Built my first Prusa about a month and a half ago, had issues with thermal runaways from day 1. Unplugging the power panic stopped the issues, so I figured the power supply was wonky. Last week, the printer powered down and shut off with a beep, then reset, then beeped off again. After talking to customer support, they sent a new heater cartridge. At the same time, I ordered a new power supply from Mean Well off of Amazon. Installed the new heater cartridge, the printer still fails with a loud shriek. Installed the new power supply, fails on the first layer like the other failures. Shriek, shut down, shriek, shut down, then announced it was doing a factory reset.


I'm at my wits end. Anyone have any ideas as to what the heck is going on here?
