    Which Caps should I order?

    Please can someone help me?

    A Shuttle SN68SG2 keeps shutting down every time I try to turn it on. Just as the login screen is about to display, it shuts down.

    (After removing and replacing the power supply, it turns off immediately after pushing the on button).

    I looked at the motherboard and I think the tops of two capacitors are slightly bulging out.

    Looking at the side I see the following printed on them:

    105°C ATWB 734A TK 6.3V1800uF

    Should I replace them (Please see attached pictures)?

    If I need to replace them, which ones should I order?

    Is this a capacitor issue? (Based on the pictures and description)?

    Is this a case of a bad motherboard instead?

    Thanks for any help!

      Good thing you wrote the capacity and voltage as you've posted two pictures with the same sides of the capacitor

      Replace with these (from best to less good):

      Yes, some of them in the list above are rated for 10v - it's safe to use capacitors rated for higher voltage so it's no problem.

      -- the capacitors in the picture are bad, replace them. It wouldn't hurt to post pictures of the whole board so we can have a look - there may be other capacitors that should be replaced even if they don't look bad.

          They are definitely domed and bad.

          Looking at the side I see the following printed on them:

          105°C ATWB 734A TK 6.3V1800uF
          I don't know who makes the original, but these will suffice

          You should also take apart your power supply. It may have bad caps in it too? If yes, then poor quality power is being sent to your motherboard which will cause more bloated caps in the future.

                  Oh, okay, thanks VERY much! (I also appreciated the pointers as I'm quite new to this. It will be the first time I do anything like this - So your input was GREAT!) Thanks!

                      Glad to be of help.

                      In case you didn't notice, the first ones I recommended are exactly the ones that are in the Badcaps store, so you made a great choice.

                      I only recommended Digikey because it may be able to ship them to you for less than 8$ as the form on this websites says. If you were in US, this website would have been my first recommendation.

                          It is $8 shipping from the badcaps.net store OR digikey.ca to Canada.

                          If you needed other things like fuses, ICs, then ordering from digikey.ca makes sense.

                              Gigabyte GA-6OXT :: caps question
                              by Foetuss
                              Good evening

                              I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                              Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                              But I was also suprised about the bigger boys, which are 330µF 25V.
                              Could it be they used 25V caps because they were cheaper / available at that time?...

                              Identifying caps on an old Zoom 9000
                              by Paxman_Swede
                              Hello!

                              I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                              The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                              I have studied the board and...

                              by momaka
                              Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                              Caps and how to find one to replace
                              by edith
                              Hello everyone I have a question. I have a laptop and his schematic. Can anyone tell me how to measure or any way to understand specific of caps so i can buy new one?

                              Also in case how can I understand if some caps of some dead Mobo i have, are ok to be replaced in my new motherboard which im trying to fix?

                              Thank you!

                              Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                              by momaka
                              I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                              For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                              It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:
