    How often do you guys do a preventative recap?

    I get free psu's all the time. When you guys get a free psu or whatever, and you open it up and find, say, Jamicon, OST, Teapo. Do you guys recap them even if the power supply is working fine and all the caps look good? Or do you wait for some to die?

    Re: How often do you guys do a preventative recap?

    When I bought a new PSU for my PC, whitin three weeks, it had new caps. I bought a new Acer monitor about one year ago, first thing after removing the packeing, was to re-cap it. I didn't even plug it in first.

        Same here, be it monitor, PS, MB, TV, or any electronic device.

          Do you even replace all the tiny caps? I usually leave the ones that don't have a vent stamp

            It depends.. I have several decent psus, all of them fully recapped and fan-modded when needed. Now, I also have 3 true-400Watt psus with badcaps that I am going to recap only when/if I need them and some 200-250-300watt that are not worth a recap with Japanese capacitors. Those if they have bulging caps they get used Chinese/Taiwanese caps as a replacement

              Good logic Although I have a recapped Allied running 24/7...I guess kind of a waste of good caps but it seems to be doing well and has a Globe Fan

                Well, me too! I have recapped that Premier DR-8400BTX, even though it would never do more than 250Watt continuous.

                At least I used Teapo at 3.3V and 5V

                    Re: How often do you guys do a preventative recap?

                    It used to power a Pentium D 2.66 (dynamic overclocking up to 3.2GHZ), 1.5GB DDR2 Geforce 7600GT, TV Card, Sata HDD, DVD-Rom and DVD-RW, until I got for free a lot of Jou Jye psus 460 and 400W, that I recapped and repaired. Now I use it for testing motherboards.

                      Re: How often do you guys do a preventative recap?

                      I preemptively recap almost everything I get. Sometimes I use stuff for a year or so if its brand new, but anything used gets re-capped before I use it (unless it has good caps to start with). Even teapoo go straight in the fire (or maybe to my bench PSU with the + and - reversed).
                      I love putting bad caps and flat batteries in fire and watching them explode!!

                              I replace ALL of them. If they can't figure out how to make a "big" cap, I'am sure they'll fuck up a "small" cap too.

                                I will recap any thing new that has a switching power supply

                                If I want to keep it a long time

                                ..... and........

                                IF this item has know BAD BRAND caps

                                ....... or............

                                I have never heard of the brand before

                                Then all of the caps will be replaced

                                Case in point I just bought a new switching power supply today and two of these brands I have never seen before ALL the caps in this power supply will get replaced

                                  Sounds like a good idea cause bad caps could fail in 6 months or even 2 years. Unfortunately last week when I was recapping a Bestec ATX-300-12Z, most of the caps I had were too big to fit on the secondary. It had OST and Jamicon, so I replaced all the Jamicon's and left the OST. They used Jamicon for the 12V filtering so I'm hoping it lasts a while

                                    I noticed some strange behaviour when running intensive 3D games or benchmarks. That went away when I replaced it with Joy Jye 460W psu.

                                    I blame that on the fake input caps that were yc 330uF 200V but their real capacitance was 220uF...

                                    I don't know. From my experience Jamicon are definitely better than most of the known bad caps. I would put Jamicon on par with OST, Ltec and who knows maybe Teapo.

                                      Jamicon would probably last in low-stress and low-heat situations - they're still going strong on all my Sound Blaster cards. But that's the best you'd do with them, I think.

                                      I've always wondered why small capacitors with inferior aluminum seem to be more prone to failure in PSUs than on motherboards. I've heard some say they're less likely to fail on motherboards because they don't take as much ripple but I always thought they were subject to a much larger surge current on motherboards then in power supplies... but then power supplies get hotter and have arguably less room to dissipate heat so maybe that's worse?

                                        Re: How often do you guys do a preventative recap?

                                        If it works well, I let it be. I don't buy new stuff so I don't do preventative recaps on that. As for old stuff - if I think I will be using it for a while and the caps are really really crappy (i.e. CapXon or Rulycon) or if there is even 1 bulged cap, I will recap most or all of the caps in that device.

                                        Also, like goodpsusearch, I have a bunch of cheapo power supplies that aren't really worth recapping with Japanese capacitors, so I put used-but-not-bulged caps in them. It's good enough for testing.

                                        Also have this L&C PSU which I partially recapped with Japanese caps:
                                        https://www.badcaps.net/forum/showpo...&postcount=490
                                        Originally, I was going to replace all of the secondary caps inside with Japanese ones, but then I got lazy and figured it wasn't worth it. Seems very stable and my old Pentium 3 PC is happy with it. 5V rail is dead on 5.00 to 5.01V, as is the 5VSB.

                                          ASUS P5GC-MX motherboard recap
                                          by momaka
                                          Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
                                          This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.

                                          So here is what the motherboard looked like with its original caps:


                                          CPU VRM area up close…...

                                          no-name Radeon 9600 XT recap and cooler
                                          by momaka
                                          I've been seeing a lot of cheap-looking (but not always so cheap) no-name AGP video cards on eBay for a while. They started popping up quite a bit when the market for AGP cards became more alive all of a sudden due to interest in “retro” PCs. One thing that struck me about these cheapo cards is that they almost always seem to come with garbage caps - including the abominable Sacon FZ. That aside, though, I've been wondering about the rest of the quality (or lack of?) on these cards. So I decided to satisfy my curiosity yet again.

                                          This one was actually suggested to me by ChaosLegionnaire....

                                          Hi all

                                          Hope this is in the correct place.

                                          I'm planning on recapping both motherboards. I actually already ordered recplament caps for them, where I will be changing out most for poly's.
                                          Could use some double checking to see if I'm not doing something stupid .

                                          Pictures of the boards are attached.
                                          What I will be replacing with what : (planned)

                                          Got 4 LG L222WS 22" for free - psu recap
                                          by goodpsusearch
                                          Got 4 CCFL 16/10 monitors for free.

                                          The resolution is almost Full HD (1680x1050)

                                          VGA Input only is a bummer though.

                                          Uses cheap TN panel with terrible viewing angles.

                                          Even though this is not 17" 5:4 screen, still has very low resell value here. Can be found for 15-20 euros.

                                          All the 4 monitors were not working and needed psu recap. Used mix of mediocre / junk caps to recap them, then donated 3 of them to friends/relatives and kept 1 for myself. Also like to install extra caps on empty spaces to help them last longer.
