Mac Pro Take Apart — Power Supply 33
Replacing the Power Supply
Note: To protect against scratches, make sure a soft cloth covers the edge of the enclosure next
to the power supply bay.
Rest the power supply on the edge of the enclosure so that its cable can reach the media 1.
shelf divider.
Note: The following four steps explain how to reconnect the power supply cable connectors
with the power harness connectors. When the power harness connectors are in their original
position in the media shelf divider, it is not possible to see where they mate with the power
supply cable connectors. Therefore, the next step shows how to temporarily remove the
power harness connectors from the divider for a better line of sight.
