My Prusa Mk2S had a lot of issues with the OEM power supply. It shorted out twice, two different spots. There will be a separate article on the Prusa problems. The solution was to replace it with a reliable well known brand, MeanWell.
Nothing is that simple. MeanWell is a different size than the stock one so new mounts need to be made. Fusion 360 and some PETG filament and we have our new part. This mounts to the same holes on the printer as stock.
