Mean Well HRP-300-24

Please Report Me If Something Bad Occurs (for Reconstruction, Correction or Something Else) I have a new power supply unit for my Prusa MK3. The original one is not bad, but I trust the Mean Well brand more. This new PSU has a temperature-controlled fan that measures 40x40x20 with load combination and Active PFC correction, providing very stable voltage under load. It's not quiet, though, because the fan starts at around 50C or more than 35% load.

Final Version, No Vibrations: One additional 24V pre-out terminal and a classic PC 4-pin molex connector (for example, like LED lights, cooling fans, modules, and many more upgrades) have been added to the final version.
