Mac Cube G4 205W Power Supply Disassembly

Ce dont vous avez besoin

  1. Mac Cube G4 205W Power Supply Disassembly, Mac Cube G4 205W Power Supply Disassembly: étape 1, image 1 de 1

    • First things first : you'll need a reasonably dead Mac Cube power supply

    • The first step is to separate these two end-caps

    • Each of them has 2 very strong (and equally brittle) clips holding it in place

    • The only way to access these clips is through the ventilation holes, .. how convenient !

    • It's enough to unhook 1 clip per side, and one of the clips cannot be unhooked, as it's blocked by some black paper plastic rubber thingy

    • It is highly recommended you go in through the marked holes (those are the largest open areas inside the PSU anyway)

    • In case you have something thin and strong enough to do this without enlarging the holes: please leave a comment down below !

    • I drilled through the existing holes to make them large enough for a fittingly stiff screw driver

    • BEWARE : this plastic is incredibly brittle and will crack very easily; using a stepped drill bit for the plastic, then a regular bit for the metal worked best

    • Once you've enlarged your holes, it's just a matter of carefully prising these clips free

    • Again, be careful, they're very brittle

    • Since peeping through a 3mm hole doesn't give one the best visibility, here's also a photo of the power supply board, so you know what to look out for ;)

    • Correctly assuming you've gotten rid of all the plastic surrounding the metal chassis, it's high time to open a bottle of something !

    • Unclip metallic end-caps with a relatively skinny flat-head screw driver

    • Now, the last step is to unhook the two halves of the metal chassis from each other - with the correct motion, this happens very easily

    • Firmly press on the top half (the bottom has the PCB laying right against it) whilst prising with a flat-head screw driver at the seam: there's 3 metal clips to unhook on each side

    • And you're done !

    • Feel free to share what problem yours had and how you've fixed it down in the comments :)

Excellent walk-through of the steps, with very kind and generous warnings. I found this VERY helpful, as I own two working G4 Cubes, with no power supplies. I’m looking for broken “bricks” to repair and finally re-use my Cubes.
