    Arer these caps ok to go into PSU?

    So ive got an old PVR here which looks to have bad caps in the power supply side. Chang / G-Luxon with a few bloated.

    So I have tried to be proactive instead of begging others to do the help right away and have put together a list from farnell of some with matching specs, but im pretty sure Ive not chosen wisely on a few. I think the FR series ones will be fine but some of the others not so.

    1800637 4 1000UF, 16V, RAD EEUFR1C102
    1800671 2 1000UF, 35V, RAD EEUFR1V102
    1907238 1 1000UF, 25V, RAD EEUFR1E102
    1800677 1 100UF, 50V, RAD EEUFR1H101
    1907235 5 100UF, 25V, RAD EEUFR1E101
    9696652 5 47UF, 50V, RAD ECEA1HN470U
    8767483 1 10UF, 63V, RAD ECA1JAM100X
    8767246 1 47UF, 35V, RAD ECA1VAM470X

    So the bottom three don't look so good? the uf/v and size of them all are matching or close enough. Just not sure if the bottom 3 are suitable for power supply? A couple look to have no polarity too which I didn't notice at first.

      use FR for all of them.

          If FR is not available in the available uF or V or size, try FM series. If no FM, then go to FC.

          PS. Just make sure your PVR is discharged. See my experience with one.

              Questions framed like yours will result in many more people likely to help you.

              So refreshing rather than the usual

                  To be fair, some of those people are clueless and have no idea where to start. They just stumbled on the forum through Google, don't know anything about electronics, and think other people have some instant and magical knowledge of their exact problem...

                      if it's like that then i'd solder a 1meg resistor across it - just make sure it's rated for 400v minimum.

                          Yea I was surprised how much charge it had stored, I think it was 244v I measured. So just shorted it out with a screw driver and got a little mini spark.

                          I forgot to check forum in morning and just went ahead and picked up the above listed caps! Isnt a issue as I can just change the FR ones for the time being and order some others.

                          But I wanted to ask could I get away with using

                          9696652 5 47UF, 50V, RAD ECEA1HN470U
                          8767483 1 10UF, 63V, RAD ECA1JAM100X
                          8767246 1 47UF, 35V, RAD ECA1VAM470X

                          Cant be any worse than the chang and teapo's. Its free delivery so can just order some others if they are not suitable.

                              dont discharge large caps by shorting, you can damage them internally.
                              the wires inside arent thick enough for the current some can hold.

                                  just changed over the FR ones and we have life. Might not bother doing the other little ones.

                                      what make / model is it btw - most dont have many caps in the psu anymore.

                                          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:

                                          Hello,

                                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                                          ...

                                          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...

                                          I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                                          I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                                          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?...
