I’m not sure the power is “dirty”, just not adequate.

I don’t think the issue is that the board designers cut cost - there’s power regulation on the boards.
The issue is that the there are a lot of crappy power supplies that don’t come close to putting out the volts/amps/watts that they are rated for. The **Power Supplies** are made with cost cutting measures and/or false marking/advertising.
Best to buy a power supply from a board reseller, that the reseller “qualifies” or recommends for the board.
