1st Gen Imac G5 20" Power Supply Acbel 661-3350 Recap possibly motherboard as well.

[ComputerGeek]

Hello Guy's, I have a 1st Gen Imac G5 20" Power Supply that I need to recap. It is a Acbel 661-3350. The Mac has one green light on the motherboard, and when I press the power button the power supply makes a squealing noise like it is trying to start.

First, does anyone have a list of caps for this PSU? I can't read the caps with them in and I am afraid that if I pull them I won't be able remember where they all went.

Second when I put the new caps in do I need some kind of glue. I read somewhere, at least I thought, that the glue stops the PSU from making noise. Can I use hot glue to the same effect?

Third, Should I Replace any Caps on the Motherboard. One of them looked a little strange on top, it was like the white powder whethered aluminium gets. I will be placing a larger order with digikey so I would rather place it with the PSU Caps then after. But, I don't want to put a whole lot into this as I don't have a Hard drive, Hard drive caddy, Memory, or OSX, I think I have a keyboard and Mouse.

Fourth, If Anyone has any of these things that they are willing to sell let me know. Hard drive, Hard drive caddy, Memory, OSX.

Thanks!

The caps in the PSU are definitely bad. The only ones you don't need to replace are on the right hand side, the two big black ones.

The caps on your motherboard look fine

The squeal is usually a sign of badcaps...and there are bulged caps on the PSU.

Im sorry, I don't.

But I have circled the caps that should be replaced in red - see if you can get their values.
When you pull them out, write down it's location number (i.e. C27, C40), and its value

Search 661-3350 in the forums.

At last count there are over 60 threads regarding these -types- of PSUs from iMacs...

You should get a good idea what caps are needed from those.
