Mid 2010 Power Supply vs. Mid 2011-late 2014 PS

Hello Dana, to answer your question, all A1347 PSUs are interchangeable. This includes mid 2010 models to late 2014, both server and non-server units. They all use functionally identical variants of an 85W compact PSU, though later PSU part numbers are technically more efficient due to different internal designs, this difference should not be significant and does not change the power pinout or maximum power that they can supply. I used to perform a DC input conversion service and used the same components for all A1347 models due to their identical PSU pinouts.
