    Evga 122-ck-nf68-ar

    Have a motherboard with bad brown and gold (GD (M) )Samxon caps. Bulging by the Memory slots/Power connect from psu and by the PCI-e slots.

    This is from one of my favorite clients. Extremely nice guy. Huge gamer. The board wasn't even overclocked and the caps still failed. I am going to put in a faster Core two for him and OC it to make him happy.

    Have two questions:

    The rest of the caps are Rubycon, green samxons. NO bulging but should I replace them too since its going to get OC'ed? Replace The little ones and the Big or just skip since they are so much better?


    Trying to get the best replacements.

    Specs for the Failed Samxon GD (M) are Impedance 18 and Ripple 1760 (2220 on taller ones)

    Relacements form Digikey :

    http://www.digikey.com/scripts/dksea...?KeywordSearch

    One is 19 Omh other is 9 Ohm. The 19 is 5000 hours vs 2000 for the 9 Ohm. Ripple is 2.18 and 2.88 Is the 9 still better for this application with shorter hours?

    There is a polymer one too.
    Is that overkill for this motherboard? There isnt much air flow where its going and it would replace the one that is bulging the most. Its ripple is 5.56 and ESR is 10.

    Apologize for the noobishness of the post. I really want to do the best for this board and for the guy. He has sent me some good referrals in the past and want to repay him best I can.

    Thank you for your help.

      Are the green Samxon labeled GF? If yes, they are a bad series and will fail sooner than later.

          Yep sure are. Thank you! Hate to get it all working then have to pull the board a few months later.

                  The link to your digi-key replacement doesn't work. What's the voltage and capacitance?

                  EDIT: The ones I think you're describing are 1500uF 6.3V Samxon GD series. The only GFs on that board are the really small ones, so I doubt if they will be a problem.

                  Replace the bad GDs with https://www.badcaps.net/store/produc...roducts_id=136

                  The polies would work in thoery, but they won't fit - they are physically bigger than the original ones.

                  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

                      Is it no harm to replace with capacitor without ripple current rating?
                      by chth96
                      When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


                      Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
                      But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

                      What are typical ripple voltages on a laptop motherboard?
                      by Antonynl
                      I have here a HP pavilion hp 15-cs2975nd with a 1.095v power supply that is driven by a FDMF3035. I do see about 80mV of ripple on my scope. I searched through the datasheet to find possible values of the ripple but I don't understand the datasheet well enough.

                      So I have two questions:
                      1) what is the typical ripple voltages of gpu/cpu on a laptop or pc mobo?
                      2) what would be the max ripple of a FDMF3035 that drives an output of 1.095V?

                      Would be nice to have a rule of thumb of say a percentage of the supply voltage to be an acceptable ripple voltage....

                      HP Inkjet printer main board bulging cap failure
                      by howardc64
                      Fixed a 10yo HP inkjet with a bulging cap on the digital computer power rails (1 to 5V). Unstable voltages causing these inkjets to not boot properly or crash quickly. Seems like more and more of these are showing up nearing the 10 year mark. Board design seem to look similar for many of these printers.

                      Is there a manufacturers tolerance for ripple?
                      by Ady2017
                      Hi all

                      I need to replace a 680uF 35V SamYoung NXB cap which has got a ripple of 1820. Whilst passing my local little electronics shop I picked up what they had in stock which was a 680uF 35V Panasonic FC with a ripple of 1655.

                      As the ripple rating is only 9% below what the original was I am wondering whether to risk it and fit it.

                      The catalogues specify a capacitance tolerance of +/-20% but state nothing about the ripple. If there is a similar tolerance for ripple then I might be worrying about nothing. Does anybody know?

                      Thanks

                      Lenovo 530 Vcore : what is the maximum ripple?
                      by Antonynl
                      Hi

                      I have a Lenovo 530 14ikb i5 8th gen motherboard and it fails to start Windows: it normally dies after I try to load Windows. Getting into bios screen works fine.

                      Made some measurements and I suspect that there is to much ripple on the 2 Vcore coils.

                      What is normally the maximum ripple allowed on say any of the power supplies? A few %??

                      The ripple is on both Vcore as outlined in red in attached photos.

                      Could be a bad driver?

                      Cheers...
