    Default Looking for GPU capacitor

    Well, I have a spare 6800GS lying around that I would like to sell off. The problem is that one of the capacitors popped off somehow or other, still a mystery to me. Does anyone know where I could go about obtaining a spare cap to replace it? I think it must be the same model number, I've tried replacing with another model and it didn't work at all.

    Cheers.

    What specs is the capacitor that you took out? It should be the same voltage and size in uF/nF... it also has to be installed in the same polarity (it will be an electrolytic cap).

    Well now you just said a mouthful. I don't suppose you could just run me through the particulars of that? How do I find out the specs?

    Thanks I appreciate it.

    The capacitor has a long and a short leg, as well as a small white stripe on the one side (cannot remember which polarity it represents though, would have to go check on one of my caps first). On the capacitor it will also say something like 100V, 10uF or whatever.

    Mm...it has nothing like that. Only has a serial number at the top. And no long leg/short leg either. I can upload a pic if you'd like

    In fact these pics show exactly the same thing as my card - even the same make of card and the same placement of the cap:

    I had one of those fall off mine. Just solder it back on. (Or get someone to do it.) Don't overheat the cap.

    Post all the info written on the cap here

    BH 100 ETZ, that's it. The thing is I don't have the original cap, but I think it's the same as the one on the right So I'm wondering how to get a replacement. I also don't have a soldering iron. Eish.

    Its a 25 volt 100uF Capacitor. Take it to an electronics store and ask them for one of those. I can't remember now which type it is exactly, would have to go and look (I mostly use radial electrolytic, which is pretty similar to these). You will need a very small soldering iron though, but those aren't too expensive. Maybe R100 or so, then get some silver solder, 0.5mm. You need about 10cm minimum (the stuff's friggin expensive).

    Ok my father in law has a soldering iron so I'm going to give this it a try this week. Thanks for the help, I'll keep reporting back.

    I'm study computer engineering... meaning I need to design electronic circuits and the like often, so I work with that sort of stuff.

    The electrolytic capacitors on motherboards and graphics cards are usually very high quality low ESR types with solid electrolytes etc. It would be advisable only to replace them with parts having the same specifications. Try Avnet (www.avnet.co.za Click Suppliers -> R -> Rubycon -> Product Range -> REV Series), RS Electronics South Africa
    SMT 105C
    http://za.rs-online.com/web/search/s...0F#breadCrumb
    SMT 125C
    http://za.rs-online.com/web/search/s...0F#breadCrumb
    or Electrocomp (www.electrocomp.co.za) for a suitable replacement. Most of the other electronic shops would only supply normal electrolytic capacitors which would have far lower specifications.

    Take a look at these discussions as well as the repair guide for more detailed information ...
