    Antec TruePower 550 - Cap issues

    got a non-working Antec Truepower 550 EPS for free..

    guess what?

    first impressions
    http://bambooz.pytalhost.net/badcaps...firstlook1.jpg
    http://bambooz.pytalhost.net/badcaps...firstlook2.jpg

    ^- just the usual puking fuhkyoos.. with 2 well-baked 35mm height Teapo SC 16V 3300uF (10/2004 datecode) standing next to them...

    http://bambooz.pytalhost.net/badcaps...firstlook3.jpg

    ^- hard to see, but that one right in front of the fan is bulging a bit

    anyhow.. i tried to get all cap values to order new pannys or whatever i could squeeze in there that should
    last a while.. and i noticed the primary caps.. fuhkyoo of course


    hmmm... that doesn't look right..

    sure enough..


    one of them is *very* light, but not leaking at the top.. the other one is noticably heavier, but the innards are flopping around loosely when you shake it..

    now here's the problem i'm having..
    there's a piggy-back PCB above those 2 caps which seems to be the active pfc.. connects to where the rectifier would be (and is) on the other threads/pics i found..





    i've got (at the very best) 32mm height.. and that would probably already touch the top PCB.

    i can't find any fitting caps anywhere
    searched for hours and all of them were either waaay too tall or too low capacitance (330uF instead of 680uF).

    i keep thinking that those 680uF caps in the pics above really are just 330uF's or something.. just like the bogus 4700uF 10mm fuhkyoos..
    (which were measured 3100uF new & unused by someone on here.. forgot who it was.. sry)

    original craps are 30mm height & 25mm dia
    200V "680"uF

    any suggestions what to do?
    - put 2x 330uF's in
    - ditch the APFC board and put waaay higher rated caps in
    - [???]

    using tiny 330uF caps in that 550W PSU.. idk... don't really feel comfy with that.. :|

    That's not completely true! I measured those 4700 caps with my micro esr meter and found them in specs:

    https://www.badcaps.net/forum/attach...chmentid=14178

    I should say also that these caps were taken out from an antec true power 2.0 380W psu that has been working for 4 years.

      You don't really need higher value input caps in an APFC unit, don't worry about that.

          problem is that i can't really find good 330uF caps either.
          most of them are small dia & too tall.. and 85°C.
          or from brands i've never heard of..

          lol!
          thought about that too.. the pic with the cut-open cap with the smaller one inside comes to mind

                          nothing special
                          just normal cap innards.. allthough they're near black and there's mold where the pins connect to the windings.. lol

                            Antec TruePower 380p failed after intermittent supply, suspect MOV
                            by rabbituk
                            Hello,

                            I have an Antec TruePower 380p PSU that I had repurposed from a Sonata case. It had been working fine on a server in the loft using the Wake-on-LAN feature regularly until a couple of recent power outages where the power became very unstable - going on/off very quickly. There is now no output whatsoever from the PSU & fan isn't working. There was a pop when I attempted to turn it on.

                            Upon examination, it appears that voltage isn't getting very far so I believe the immediate issue is within the first stage. There is a green component that I am not familiar...

                            Yes, I know I don't post this stuff much anymore....the only reason I'm posting this one is because of a NVMe adapter incompatibility; seems rather planned by Supermicro.....or I'm atleast a bit suspicious. It's plenty new enough to have a UEFI bios but a short 'happy list' of NVMe controllers that will work with this board, as if by some 'miracle', all Intel....so lets start at the beginning; we'll get back to this later.

                            Of course the motherboard is as the thread title states; X10dai....but we'lre going to have some fun shoehorning this into a modern 'gamer case' that can actually...

                            Hi, trying to troubleshoot some problems with this laptop I just finished repairing which had power issues (Burnt Buck converter - SY8883DFC shorted to ground).

                            After repairing the above issue, I realized the following remaining problem,
                            Sound only comes from bottom speakers, top palmrest speakers don't work. Neither does the headphone jack (static/buzzing).
                            The computer recognizes headphones are connected and displays a popup in windows
                            Sometimes, the computer will boot up and the sound will be working fine. However, if I run intensive programs and the computer...

                            Lenovo IdeaPad Gaming 3 15ACH - Ideapad 3 well known solder joint issues
                            by Nagyesz
                            I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.

                            All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..

                            How can I extend its lifespan? Could reflow help?

                            It has ryzen 5 5500h, rtx 2050, no soldered ram.

                            Example of the artifacts:
