    GeForce 6800GT recap, need help identifying caps and finding replacements

    Hi,

    I just noticed that my Asus V9999GT (GeForce 6800 GT) had some swelling capacitors. I managed to identify the brown ones, which are Nippon Chemi-Con KZG series, 6.3V 820µF, which I plan to replace with this.
    But for the yellow ones, I guess these are Fujitsu caps, without being able to identify which series... A picture of the video card is attached to the topic.

    I need to replace:
    • 2x 2.5V 1500µF => I plan to use this
    • 2x 16V 330µF=> I plan to use this
    • 1x 6.3V 680µF=> I plan to use this
    Am I correct with the cap choices?

    Thanks for your help.

    polymers are a good choice - make sure the diameters are the same or the lead pitch wont match

      Hi, thanks for your reply. Diameters are identical, I'm just worried about differences in ESR values, and I'm unable to find the ESR values on the caps. I only found that the KZG are low ESR, without any additional information.

        on gpu's low esr is essential because of the frequencies they run the psu section at.

          So the caps I mentioned should be correct?

            They look fine but there is probably no point in replacing those Fujitsu caps: they are good quality...
            And when replacing the UCC KZG caps I would go for a same-same replacement (same capacitance).
            Something like this: https://eu.mouser.com/ProductDetail/...PWDmuM8Q%3D%3D

              Alright, I will order this reference then. Thank you Per Hansson. The Fujitsu are not swelling so I won't replace these ones.

                ASUS P5GC-MX motherboard recap
                by momaka
                Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
                This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.

                So here is what the motherboard looked like with its original caps:

                no-name Radeon 9600 XT recap and cooler
                by momaka
                I've been seeing a lot of cheap-looking (but not always so cheap) no-name AGP video cards on eBay for a while. They started popping up quite a bit when the market for AGP cards became more alive all of a sudden due to interest in “retro” PCs. One thing that struck me about these cheapo cards is that they almost always seem to come with garbage caps - including the abominable Sacon FZ. That aside, though, I've been wondering about the rest of the quality (or lack of?) on these cards. So I decided to satisfy my curiosity yet again.

                This one was actually suggested to me by ChaosLegionnaire....

                Gemcon capacitor replacements?
                by slybunda
                taken from my thread about car alarm siren here: https://www.badcaps.net/forum/troubl...rm-siren-issue

                there are 2 caps which im looking to get replacements for.
                Branded as Gemcon
                single 100uf 16v 6.5mm x 11.5mm
                single 100uf 50v 8mm x 11.5mm
                lead spacing is around 3mm

                there is space for 16mm tall caps

                rs components is good place for me to go since its close by, what replacements do you suggest and do these need to be low esr?
                the caps have...

                Need Help Identifying A Diode
                by RetroComputingGrotto
                I have an MSI 3PA1 monitor on my bench that wont power on. I have tested the 2 (what I believe to be Schottky Diodes) and both are shorted in both directions (a common faulty from what I can see on Google) but I'm not certain what the markings on the Diodes mean so I need some help in identifying which ones to order from Mouser please?





                I've done a search for 101C 5100C and all I can find are datasheets for 5100C which say they are 20-100V 5A Schottky Diodes but I'm not 100% sure if this is correct or not and what significance the 101C is.

                We...

                by Khoja
                Hello friends, I have a Lenovo Ideapad Flex 5 14IAU7 laptop that doesn’t turn on. When I opened it, I found a burnt resistor on the motherboard. Since I couldn’t find a schematic for this model, I need help identifying the parameters of this resistor.

                Any assistance would be greatly appreciated!...
