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

    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.

                              iMac A1418 - No LED, no power after overvoltage on Ethernet port
                              by ryogadan78
                              Hi guys, I need your help again.
                              I have this iMac from a customer that shut down during a storm along with all the other devices in the house. In particular, the router, connected via Ethernet to the iMac, caught fire.
                              When I removed the screen from the iMac to check the status of the LEDs, I noticed that none of them were lit. I had a perfectly compatible and working power supply, so I tried it right away, but the problem remained the same (no LEDs). With the thermal camera, I noticed only a slight warming (32 degrees) of the NCP1605BG chip on the power supply. The rest was completely...

                              iMac M1 DFU restore issue
                              by Stephen
                              iMac turns on no drops no cracks, tried to DFU Restore the iMac, logo turns on great! however iMac turns itself off and then restarts to the (!) icon and won't post the restore. Tried thunderbolt 3 cable, tried regular USB C cable and nothing.

                              this is the message it gives me with the error

                              Unexpected device state 'DFU' expected 'RestoreOS' (Probably forced into DFU mode externally) [com.apple.MobileDevice.MobileRestore – 0xFAE (4014)].


                              Any thoughts what this could be? I will open it up and repair it but I am not 100% sure since this iMac doesn't...

                              iMac 27” 2020 Boot issue
                              by Stephen
                              Customer came in for data recovery, came to find out data is soldered on to this iMac (learn something new everyday) this is a 2020 T2 iMac so I was surprised because the iMac Pro has a T2 chip and it isn’t soldered on. Anyways, the iMac boots to Apple logo and then restarts, before it turns off you hear a quarter fan spin then it repeats itself. I decided to do a DFU revive to restore any hardware firmware issues and it was successful in reviving the device however the issue persists in boot looping. It shows the Apple logo for like 40 seconds then turns off and fan spin rinse repeat. I...

                              recap help AcBel PSU
                              by pavithra_uk
                              I found used PSU AcBel PC6001 ~250W from IBM thinkcenter Core2Duo system. Almost every output rail caps were bulged except 12V rail single cap. caps were Ltec

                              12V - 1200uF 16V
                              5V - 1000uF 10V before coil 1000uF 10V after coil
                              3.3V - 1000uF 10V before coil 1000uF 10V after coil
                              5Vsb - 1000uF 10V before coil, 470uF 16V after coil


                              Since I have no access to buying new branded caps, I'm going to replace caps with used caps I pulled from dead PSUs and Motherboards.

                              I need cap experts ideas about it.
