    Caps getting Hot!!!!

    Hello everybody on forum,

    I came across lots of boards with badcaps. Some of them are leaky, bulged or getting hot. But recently I had a ASRock P4i65GV motherboard with 2.8GHz HT processor & 1GB RAM. I noticed that almost all caps across CPU are getting extremely hot (untouchable). Even the coils with ferrite cores are getting hot. At present motherboard is working well except CMOS settings are getting lost when PC is switched OFF and ON (battery is changed but of no use). What might be the reason?? Can anyone throw light on the condition of this motherboard.

    Thank u.....

      What power supply are you using?

          I tried with different SMPS of 400W to 500W. But problem persists.

              Does the CPU cooler blow up, away from CPU, or down towards CPU?

              If down, then it's probably time to investigate and replace those caps. If up, then get a cooler that blows down. You need air moving across those caps.

              Either way, I'd check out those caps. If you can, report the make and series of the caps.

                  Ya, but if you are using some cheap'o no-name psu they can cause the same thing.

                      Ok...now I came to point that the cap (1000uf) on the besides USB socket is getting hot first and then others are getting hot including FETs (small flat transistors mounted flat on motherboard). Replacing with same rating causing it to getting heated and bulge immediately. What could be the problem? Can anybody help???? Plz..........!!

                          >>Replacing with same rating causing it to getting heated and bulge immediately. <<

                          Did you put the caps in correctly observing the polarity markings?

                          What caps were there? What caps did you use to replace them with?

                          As I asked before: If you can, report the make and series of the caps.

                              What brand and voltage caps were there before; maybe it was a bad recap job.

                                  Sounds like the caps were replaced with high ESR caps. What was and what is there now?

                                      I agree with above.

                                          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?...
