    DFI Lanparty nF4 Ultra-D

    Hello Everyone,

    My trusty old DFI Lanparty nF4 Ultra-D has finally died on me and I would like to revive it. Upon inspection I noticed 3 bad caps as seen in the photos below:



    2x chemi-con KZG 1500uF 6.3V
    1x chemi-con KZG 470uF 16V

    I did some searching on the forum and see that these KZG caps are notoriously bad so I think I will replace them all. I also saw a similar thread which recommends the following replacements:

    Rubycon MBZ/MCZ
    Nichicon HM/HN
    Panasonic FJ/FM

    I took a look on the bad caps store but none of these seem to be available. I checked on Mouser and found the Nichicon HN but they are back ordered. Only thing I found in stock is the Panasonic FM, would these work?

    Panasonic FM 1500uF
    Panasonic FM 470uF

    If not, can anyone recommend replacement caps for my KZG? (something in stock online)

    Thanks!

      no the 470uF 16V panny FM is too fat with a 10mm diameter. it wont fit since its right beside the pcie slot. the 470uF 16V kzg u have has an 8mm diameter, i believe.

      the two 1500uF 6.3V kzg caps that u have bloated are at a buck regulator. it will be better if u use ultra-low esr caps there. the 1500uF 6.3V panny FM may be too tall. i believe its also very close to the cpu heatsink. putting a 20mm tall cap there may cause obstruction with the cpu heatsink esp. if u use a third party cpu heatsink.

      so u'll have to try poly modding the board. there is a similar version of this board that had all poly caps called the DFI LANPARTY nF4 SLI-DR. saw one on ebay the other day.

      the 470uF 16V electrolytic caps can be replaced with either panasonic oscon sepc or chemicon psc 270uF 16V poly caps. the 1500uF 6.3V kzg caps can be replaced with either panasonic oscon sepc 680uF 6.3V or chemicon psc 820uF 6.3V poly caps.

      btw, it seems that u must have used a high end hot graphics card in the board's pcie1 x16 slot. so no surprise that the 470uF 16V cap under that slot bloated. therefore, i personally recommend poly modding as the caps are more tolerant to heat.

          Hi Chaos,

          Thank you for the detailed reply. I must not have checked those dimensions correctly last night but you are right. The 470uF is listed as 8x11.5 and the 1500uF is listed as 10x12.5. This seems strange since visually I can see the 470uF has a larger D and the 1500uF is almost 2x the height...

          Are there no low-esr aluminum-electrolyte caps available in the market right now? Is poly my only option?

          If I switch to poly caps am I required to switch all the caps on the board or could I just change these to poly caps?

          Thanks!

              Just went back and measured the caps, the 470uF is definitely 8x11.5 like the spec sheet however the 1500uF seems to be 8x18 or so... definitely not 10X12.5...

                  all of the good japcap manufacturers deprecated their ultra-low esr electrolytic caps in favour of polymers which are more resistant to heat and more reliable as ultra-low esr caps.

                  u just need to replace all the kzg caps on the board. the ky caps are good and do not have issues so u can leave them be. its actually okay to mix and match electrolytics and polymers. i've seen a few boards on here by other members that do that in the cpu vrm and they're fine.

                  its most likely a custom order. cap manufacturers can make custom sizes for mobo makers if the order is large enough.

                      Looks like Topcat has some MBZ/MCZ stock left so I will just go with those.

                      Thanks for your input!

                          Poly VVX-250 VOIP POE problem not booting fix
                          by CapLeaker
                          I've got a bunch of Poly VVX-250 VOIP phones that work fine as kind as long as they are plugged into the wall wart. Recently I got around to install a couple of TP-Link 5 port POE switches that are added to the existing plain Jane 24 port unmanaged switch. Great!!! Finally I am able to ditch the wall warts from these phones making more space on the desk, plus I am gaining some badly needed power outlets. So I thought.

                          Plugged in the first VVX-250 into the POE switch, booted up no problem. Plugged in the other Poly phones and they start to boot anywhere from 5 to 15 seconds,...

                          by RukyCon
                          Hello Again, so i'm bringing back this Zumax PSU from the gutless thread and going to be doing some modifications, and also putting it into a PC i'm going to throw together out of spare parts to see how long it lasts.

                          So the first thing i did was fill in the missing filtering, by replacing the cheap common mode choke with a real one and adding a 470nf X2 capacitor in the open capacitor spot, i then replaced the fake Y-class capacitors with real ones, i also swapped out the mismatched primary caps with a pair of Aishi WK 470uf 200v caps, both of which test around 520uf. I also swapped...

                          Apple NVIDIA AGP GeForce 6800 GT Dual Link DVI+DVI outputs 603-6338 missing caps!
                          by jpreza
                          Hi everyone,

                          I recently acquired this card from a seller who was selling a PowerMac G5 for parts. He mentioned that the video card was probably broken too.

                          Upon closer inspection, I can tell the reason why it won't work: it's missing a bunch of CAPS! (it's also missing an inductor - 1.0uH).

                          It's a nice card as it's one of the few AGP cards that will support 2560 x 1600 resolution on a PowerMac G5 using a 30" Cinema Display.

                          Looking at the card, it appears to be missing the following:

                          1x 1.0uH inductor - orange square
                          2x...

                          Soyo SY-7VBA133U recap
                          by rattlesnake
                          Hi guys,
                          I'm going to recap this baby. I found it dumped in the street years ago, and now it's time has come. I remember having tested it and it posted back then.

                          Original caps are bulged and look nasty. All are SACON
                          11 x 1000uF 10v
                          12 x 1500uF 10v
                          1 x 470uF 16v
                          11 x 22uF 25v
                          1 x 10uF 25v

                          The smaller ones look fine. Should I replace them too?

                          I read on another forum that I could replace the 1500uF caps with 2200uF caps. Is that so?
                          The thing is I could get Sanyo 2200uF or Capxon 1500uF (or Jackon 1500uF)....

                          Need Help Identifying Parts on a crossover and a few other newbie questions
                          by UL161
                          Hi I am trying to refurbish this crossover with some higher quality poly-caps/parts... The speaker is a in-wall Polk 65-RT... Key questions I have are:

                          1) What in the world is the yellow part on the board (label is MET 1.0J 100V)?... Should I even consider replacing it?
                          2) The 470uF cap.... Does anyone know have a suggestion as to where I can find a reasonable audio quality polycap near that value? (or at least 3 160s or the like?) { I don't want to spend $70 just to replace this one if I can) (maybe even someone looking at this circuit could even tell if this cap is important...
