    badcaps in a ATX PSU

    hello i have a good PC PSU which i got from HSC Electronics used for $6 on sale.

    now i say the PSU is good but it's not 100% good because i wanted to open the power supply up (just to see how it work) but then i spotted 3 bulging capacitors brand GL [note there are also canicon caps in the PSU]
    cap1&2 is a 2200uf 10v
    cap3 is a 680uf 16v
    now that is the bad ones but there are a lot more and they are not dead or dying should i just replace the bad ones or should i change them all out and what brand cap should i use?

    here are some pictures i took



    here are the bad caps

    i hope you can help. thank you

    Re: badcaps in a ATX PSU

    change all of them.
    if you where in europe i would say use panasonic FR series,
    but in the states other decent brands are cheaper for some reason.

      okey that's good to know

      at first i thought they were dying do to heat because i found them in a poorly ventilated part of the power supply

      but i did see a case where the canicon caps had died posted online by Kevin! on badcaps

      i'm glad that i open the PSU up now because who knows how it could have failed

          check prices at digikey

          before you do, make a list including the diameters.
          some company's make caps that are wider & wont fit - something to watch out for.

            Nice PSU. Needs a full recap. All of those caps are going to have to go except for the big high voltage caps. Typically for ATX SMPS, I use nichicon PW, HE, Panasonic FC, Rubycon YXF, Chemi-Con KY/KYB. You should be good height wise, just make sure you don't get any caps bigger than d10mm

              Canicon hasn't existed for a long time, but they probably make caps under a different name now

                  you often dont need to replace the high voltage cap(s)

                      Honestly, I think ZLH/ZLJ is too low ESR for PSU

                        I think FR is too low as well, you're talkin 0.018Ω, that's pretty low for a PSU. I bet you the original Canicon were much higher in impedance. You don't want to try and jam 12.5mm caps in there anyways. I'll recommend some when DigiKey's site isn't down

                          DigiKey should carry Nichicon PW, UCC LXZ, and Panasonic FC. Those are very similar series, and should be reasonable matches for what was originally in that PSU - in terms of impedance and ripple current rating (the quality will be much better).

                            ok good to know i chose rubycon ZLH because i found some in a PlayStation3 PSU and the panasonic FR because stj kinda recommended it to me

                              the new caps i'm looking at now are

                              the rubycon ZLH 680uf 16v is now a chemi-con KY http://www.digikey.com/scripts/DkSea...97610346542927

                              can not find a exchange for panasonic FR 3300uf 10v

                              im looking at getting a chemi-con KYB for the 2200uf 16v cap but it's a bit tall [16mm vs 31.5mm http://www.digikey.com/product-detai...869-ND/4843679

                              can not find a exchange for rubycon ZLH 1000uf 16v

                              2200uf 10v is still a chemi_con KY

                              if you know of any other options then i would love to know
                              thank you

                                Get rid of that tan glue. It turns brown and goes conductive

                                I had an HP small form factor power supply short out from that glue. It took me over an hour of scraping to get it out.

                                  instead of the pana FR, check the spec on FK

                                    You really don't need 3300μF for the minor rails. You can use 2200μF 10V for the 5V and 3.3V rails.

                                    http://www.digikey.com/product-detai...1509-ND/756025

                                    Those 2200μF 16V KYB will work well for this PSU, they are actually 10x30mm

                                    You can use these for the 1000, 16

                                      i look for it as a 3300uf 10v cap but i can not find it as one

                                        You also don't need 10V caps for 5V and 3.3V rails. Since you want to get d10mm caps and want to keep 3300, get these:
