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.
