Use this guide to replace the power supply in your Mac Pro Late 2013.

Before beginning any work on your Mac Pro: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

  4. Mac Pro Late 2013 Power Supply Replacement: step 4, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 4, image 2 of 2
    • The fan assembly is attached to the rest of the computer by two cables on the IO board side.

    • Tilt the assembly up away from the IO board.

    • Do not try to remove the fan assembly yet, as it is still attached by two cables.

  5. Mac Pro Late 2013 Power Supply Replacement: step 5, image 1 of 1
    • While supporting the fan assembly with one hand, loosen the two T8 captive screws in the fan cable bracket.

    • These screws are captive in the Mac Pro. Do not try to remove these screws from your Mac Pro.

    • Use a pair of tweezers to pull the fan cable bracket away from the fan assembly.

  7. Mac Pro Late 2013 Power Supply Replacement: step 7, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 7, image 2 of 2
    • Use the flat end of a spudger to disconnect the fan assembly ribbon cable from the IO board.

    • Disconnect the fan assembly antenna cable from the IO board.

    • Remove the fan assembly from the Mac Pro.

    • Flip the Mac Pro upside down, 180 degrees.

    • Remove five 5.1 mm T10 Torx screws from the outer perimeter of the lower case.

  10. Mac Pro Late 2013 Power Supply Replacement: step 10, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 10, image 2 of 2
    • Carefully lift the lower case up and remove it from the Mac Pro.

    • Use the flat end of a spudger and a twisting motion to gently separate one side of the graphics card data connection.

    • Gently separate the other side as well.

    • Flip the connector up and out of the way of the graphics card.

    • Repeat this procedure on the other graphics card.

  13. Mac Pro Late 2013 Power Supply Replacement: step 13, image 1 of 1
    • Remove the two 6.0 mm T8 Torx screws securing the interconnect board to the heat sink.

    • Gently walk the interconnect board straight up off the logic board's slot connection.

    • It is recommended to lift one side and then the other.

    • Do not try to remove the interconnect board from the Mac Pro yet, as it is still connected to the IO board.

  15. Mac Pro Late 2013 Power Supply Replacement: step 15, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 15, image 2 of 2
    • Flip the interconnect board up and over, exposing the IO board data cable.

    • Use the same sort of twisting and spreading motion with the flat end of a spudger to separate one side of the IO board data cable.

  16. Mac Pro Late 2013 Power Supply Replacement: step 16, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 16, image 2 of 2
    • Use the flat end of a spudger to separate the other side of the IO board data cable.

    • Bend the cable out of the way and remove the interconnect board from the Mac Pro.

  17. Mac Pro Late 2013 Power Supply Replacement, Power Supply Assembly: step 17, image 1 of 1
    • Flip the Mac Pro back over and set it gently on a flat surface.

    • We recommend laying the Mac Pro on the corner of the heat sink and the two standoff screw posts that attach to the interconnect board.

  18. Mac Pro Late 2013 Power Supply Replacement: step 18, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 18, image 2 of 2
    • Remove the two 3.6 mm T5 Torx screws from the sides of the power supply cage (one on each side).

  19. Mac Pro Late 2013 Power Supply Replacement: step 19, image 1 of 1
    • Remove the power supply cage from the top of the power supply.

    • By removing this cage, you are exposing internal components of the power supply. Be very careful not to touch any of the power supply components or circuitry.

    • Be careful not to drop any screws or tools into the power supply, as this may damage the power supply.

  20. Mac Pro Late 2013 Power Supply Replacement: step 20, image 1 of 1
    • Remove the four 5.5 mm T8 Torx screws securing the power supply assembly to the Mac Pro.

  21. Mac Pro Late 2013 Power Supply Replacement: step 21, image 1 of 1
    • Remove the power supply assembly from the Mac Pro.

    • Use the flat end of a spudger to disconnect the power supply DC-Out connector from its socket on the IO board.

    • Use the tip of a spudger to disconnect the power supply data cable from its socket on the IO board.

    • For both cables, make sure to pry straight up on the connector, and not the socket.

  23. Mac Pro Late 2013 Power Supply Replacement: step 23, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 23, image 2 of 2
    • Remove the four 9.0 mm silver T10 Torx screws from the sides of the power supply.

    • The power supply overhangs these screws somewhat, so you'll need to use a fixed screwdriver at a bit of an angle.

  24. Mac Pro Late 2013 Power Supply Replacement: step 24, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 24, image 2 of 2
    • Gently shift the power supply to free the AC power inlet cable out of its plastic clip.

    • Be careful not to try to separate the power supply from the IO board assembly just yet, as it is still connected by the AC power inlet cable.

  25. Mac Pro Late 2013 Power Supply Replacement: step 25, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 25, image 2 of 2
    • Flip the power supply back to expose the AC power inlet cable.

  26. Mac Pro Late 2013 Power Supply Replacement: step 26, image 1 of 2 Mac Pro Late 2013 Power Supply Replacement: step 26, image 2 of 2
    • Squeeze the AC power inlet cable connector and pull it straight out of its socket in the power supply.
