    A7N8X bad caps reboot?

    I ordered a power supply because I thought my random reboot was due to a bad PS. When I opened the case and shined a flashlight onto the mobo, I found 8 bad caps on my A78NX Deluxe. I guess that's the reason for the random rebooting. Wonder if I'd be better off ordering a combo mobo/cpu and use existing ram?

    (sorry about the crappy cell phone pic) but you can see the crud that has surfaced at the top of each cap.

      I think it depends on you: if you want to try to save it, I think you are going to save some money.
      If you don't have the tools to recap your board, you must ask to someone and see how much it cost.

      If I were you, I would try to recap it, if the only problem/reason you have is "random reboot" .

          Woops, posted in the wrong area. Can admin move this to the Bad caps area under the Aopen-Asus- group of questions?

              Regarding the rebooting issue...is it due to the bad caps or the sign of a bad power supply? When I checked the system bios, the 12 volt line was 11.8 or so and the 5 volt line was 4.5 to 4.8 and the 3 volt line was 2.5 to 2.7...

                  Either of them can cause it.
                  You can have one problem or both problems at the same time.

                  Either of them can cause this too.
                  Output filers in PSU are in parallel with most caps on mobo.

                  Also bad caps on mobo can make PSU caps go bad.
                  Bad caps in PSU cam make caps in mobo go bad.

                  If you have cap problems anywhere always check both psu and mobo.

                      those voltages are way off.
                      try another psu.

                              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:

                              Heathkit IO-4205 Power Supply Caps
                              by eryjus
                              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."
                              ...

                              Identifying caps on an old Zoom 9000

                              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...

                              Help with switching power supply caps
                              by captain150
                              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,...

                              Gigabyte GA-6OXT :: caps question
                              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?...
