    NForce 680i SLI Bad Caps 122ck-NF68-B1

    I'm working on replacing some bad caps on this motherboard. Much to my surprise, someone actually pulled a couple of the bad caps off the motherboard before I got to it. Does anyone have one of these boards so they can tell me the specs on the caps in the attached picture. Need size, voltage, capacitence. Thanks.

    They look like 1500uF 6.3V caps to me, but I'm not totally sure.
    I love putting bad caps and flat batteries in fire and watching them explode!!

    No wonder it doesn't work! You installed the jumper wires backwards

      In one picture I found on Google images, the board uses Samxon GC series : http://home.comcast.net/~lukefencejumper/bakincaps.jpg

      The caps around those two big ones are also Samxon, GF and GS series.

      On other boards, they're Rubycon or Nichicon.

      They seem a bit too large in diameter compared to the others around (the ones between the RAM modules and the ATX connector are 1500uF/6.3 and they're much smaller, at 8mm diameter) so I would guess they're rated for 16v.

      From there, just at the top of that capacitor, it looks like there's a 1 and a part of a 0 ... so I would *guess* 1000uF but it could just as well be half of the 6 from 16v

      On this other image : http://home.comcast.net/~machaevich/...3/site1053.jpg

      You can also see a 0 and probably half of another 0 and the Z - it's a Rubycon ZLH or ZL1 or one of the series that starts with Z.

      It could be a 1000uF, 1500uF, 2200 uF... sorry, can't tell.

      What you could do is measure the diameter of that circle - in both pictures, the cap is exactly the size of that circle, so if that one is 12.5mm for example, you might eliminate some more choices.
      For example if the circle is 12.5mm in diameter then... Samxon GC , 12.5mm , the smallest 6.3v rated GC at 12.5 mm diameter is 3300uF which is unlikely... but the smallest 16v rated GC is 1800uF which seems more reasonable.

      Also, look at the + side of the capacitor, see on the back of the board where the trace goes... if the trace goes straight to the ATX connector, tell us which pin is that.

      If it goes to some chip, say what's written on the chip.

        Caps on the corner aren't taken off. They come off from rough treatment. The two caps on the corner are the same as the ones on the 12v side of the CPU VRM.

        EVGA nForce 680i 180-7R093-0000-C00

        C12J9, C12K1, C12B3, C11A6, C9A10, C8B18: Samxon GF 1800uf 16v 10x25

        This board is some effed up s. TOO MANY CAPS!
        sig files are for morons

          10mm? I thought they looked like 8mm.

            Thanks everyone for your help. I'll throw a couple 1800uf 16v 10x25's quality low ESR caps in and see what happens! They are definately tall 10 mm caps. Putting somrthing that big and tall that close to the corner of the board is just begging for them to get abused.

              Just to close out this thread, I replaced the caps and the motherboard is now living again. Thanks to everyone for their help.

                  Hello! Much to my surprise someone has posted about this motherboard. Rummaging through my old stuff, I found this board I kept from years ago that was in need of repair. After a physical inspection, I noticed that C15D2 is missing from the back of the board. Without a boardview diagram, I have no idea what this Cap is.. Could anyone shed some light on how to go about finding the value of this cap?

                  This is my first post aside from the introduction post. Please accept my praise to the mega minds of this forum

                    Hi Mike, welcome to BCN!

                    Could you post a picture of the board where the cap is missing? It almost sounds like a small ceramic cap from your description. If that's the case, those are rarely critical. But without pictures and a description where the cap is located, it would be hard to say more. A boardview might exist somewhere, but "issue" here might be pretty easy to figure out without one.

                      Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!

                      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
                      by Paxman_Swede
                      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?...
