Going to recap one of my four cube psu and see how it goes., what a pain to get into lol. Thank god not a lot of caps..
Thanks! Will definitely check that out for suredouble check all solder joints while your in there. on mine i had cracked joints on the main 22 pin wiring harness to the board.
the cube Psu are known to die. This is my first time seeing if I can recap one. Have to order caps todayIs this a proactive recap, or is the PSU dead? Just wondering if this is worth doing on a working PSU. I don’t have a lot of experience with the cube - are the PSUs prone to failure?
Not that i have seen. Always an issue with connector to computer and it is 28v psu. So would rather keep original if possible. Will see if it worksWouldn’t it be cheaper and easier to replace the PSU by a modern one? They are more efficient and produce less heat. They’re more compact too: a modern open frame PSU could fit inside the original case of the Cube PSU.
I was talking about replacing only the electronic board (that’s what an open frame PSU is). You just have to figure out how to mount the new board inside the original case and rewire the cables. No issue with the connector!Not that i have seen. Always an issue with connector to computer and it is 28v psu. So would rather keep original if possible. Will see if it works
Yeah, I had a dead Cube PSU and I replaced it with an older 27v mean well PSU. I did have to 3d print a piece to extend the length of the case. However, I think newer PSUs may be able small enough to fully fit into the original case. Definitely something to keep in mind if the recap goes poorly.I was talking about replacing only the electronic board (that’s what an open frame PSU is).

I had already looked into it (but not done it, my Cube PSUs work fine), and a Mean Well EPP-400-27 is a good replacement candidate. It’s not cheap, but big capacitors aren’t either, and they add up quickly!
It wasnt bad really. Only issue is unsoldering some caps that were attached to the huge copper plate. Honestly no caps “looked bad” but i can see where a ceramic something was getting hot right beside a 1000uf 35v cap.Was it easy to take apart - (I guess not, any hints)? Did you use someone's list for the caps or did you order them once you had it opened and checked them out?
If you put together your own list, could you share it, along with the model number of the PSU?
Lol, yes he must have had nightmares over fans.. i guess he figured he had enough apple fans like us he didn’t need any moreThanks for the report out. I am going to be looking after mine eventually and just wanted to know what I would be in for, so thank you very much.
Can you imagine the alternate universe where young Steve did not have one of these in his bedroom, keeping him up all night and did not grow up hating fans...

...and occasionally listened to his engineers about the whole cooling, mumbo-jumbo early on?
Of course, he figured you would just throw it away and buy the new one two years later, anyway.
I might need a little more sleep, since I laughed quite a bit longer than I should have at that...guess he figured he had enough apple fans like us he didn’t need any more
glad it had some humor!I might need a little more sleep, since I laughed quite a bit longer than I should have at that...
