    I think this capacitor is bad but can't tell

    So in my Linux Router, I have an FSP power supply. This one specifically: http://www.newegg.com/Product/Produc...82E16817104045

    It hasn't been used that much. It was in a HTPC for about 3 months and in my Linux router running for only 3 weeks straight now. The primary caps are CapXon, and from what I can see, there are some Teapo and CapXon on the secondary side. I looked inside the PSU, from the back grille while it was running and it looks like one of the main caps is bulging a little. Since it is somewhat hard to see, I can't tell if it's bad or just the angle I'm looking at. I'm lazy and I don't want to actually shut it down and take it out and open it since it's still under warranty and it's still powering the computer just fine. So I am wondering, even being CapXon, what are the chances that one has gone bad on the PRIMARY side just after a few months of use??? The only Primary caps I've seen die are Fuhjyyu's

    Just in case, all it's powering is a Pentium 4 2.8 no HT, 2 RAM sticks, 1 hard drive, no graphics card, and 2 case fans. In other words, nothing.

    Primaries bloating after a few months is unlikely, even if they are Capxon. Are you seeing the top of the capacitor bloating, or is the top of the capacitor covered with a plastic disc? The plastic discs will bloat from heat and the air trapped under the disc expanding. A bloated plastic disc does not mean the capacitor under it is bad. FSP isn't the best quality, but they're not "gutless wonders" either. FSPs don't usually have "warranty seals," so you can open them up to check the condition or clean them without voiding the warranty.

      Thanks for the reply! Yeah the top of the capacitors have plastic discs on them.

        It's called insulation. [hehehehehe]
        They sometimes do that on big caps to reduce the risk of shorting something.

          Okay cool, that makes me feel better. Thanks!

            KingWin ABT-650MM 650 Watt ATX PSU [PCB: SW8835REV:A]
            by momaka
            For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
            http://www.rmac.kingwin.com/products.../abt_650MM.asp

            I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.




            What mostly drew me into buying it is its 2x PCI-E power connectors...

            RTX 3080 FE Identifying capacitor
            by Prolog
            Hi people, I hope this is the correct spot to post this, I'm new to the forum.

            I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

            I hope these photos make it clear which component I am referring to:
            (yes, the soldering is a bit botched from removing the blown one, I know)

            I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

            If I replace with inferior capacitor, Is it No harm to other IC components at all?
            by chth96
            I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
            Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
            It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
            So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
            I know that these capacitor will not last as long as nichicon capacitor...

            How can I test non-polarized capacitor?
            by chth96
            I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
            I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

            And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
            I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

            Is it no harm to replace with capacitor without ripple current rating?
            by chth96
            When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


            Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
            But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
            Rubycon YK DataSheet (b...
