    Epox 8rda3+ crap cap job - need values

    Anyone here got one of these boards?
    Just brought one, but it has being sloppily recapped with Matsushita NHG caps - which i believe are general purpose.
    Am also suspicious that a few of them are the wrong value/size/voltage, when comparing photos of the board

    If you have one of these boards floating around, could you please have a look and let met know the values (capacitance, voltage and size),
    so that i can recap it properly

    Thanks

    (the photo is not of my board, but rather, what the original would have being - same model and version)

    In your circle you have the CPU VRM. Fill that area with 2200uF 6.3v caps of good make (Rubycon MBZ/MCZ, Nichicon HM/HZ, Panasonic FJ/FM/FL) and it will be just fine.

    Those Matsushita/Panasonic NHG are likely to be fake and you should replace all of them.

      Thanks for the reply, Th3_uN1Qu3
      So, am i right in saying that these caps are not suitable for a motherboard?
      Have attached 3 photos - do they look like fakes?
      Just went back and did another search and found exactly what i was looking for - courtesy of member, Per Hansson
      So yay! - made my day.
      Interesting to note that the VRM output caps are 3300uf, and that there is 6 of them - because on the microstar boards that i have, there is usually 6 X 2200uf on the vrm output, and 3 X 3300uf on gigabyte
      Why is there 6 X 3300uf on this board, rather than 3?

        You have no way of knowing what and how many caps were there originally. Maybe they were 2200uF but whoever did the recap decided to put 3300uF ones instead. The Panasonics you have there look to be genuine, but indeed, they are not suitable for use in the VRM of a motherboard.

          Here is a list of the stock caps from a board that I have, hope it helps.

            i forgot to post the link
            Here is the link

            like you, and from what i have seen on other boards, i was thinking the vrm output would have being 2200uf, but they were indeed 3300uf

            seeing the 3 chokes, i assume that the vrm is 3-phase
            would that be a reason why there is 6 X 3300uf, rather than the 6 X 2200uf on my other boards, which are probably 2-phase?

            thanks for that list Sparkey

                If it helps, my old EPoX 9nda3J has the same VRM layout and were all Sanyo WG capacitors. The first row was 6x 6.3v 3300uf, the back row consisted of 3x 16v 1500uf capacitors.

                The majority of the other next smaller sized caps down across the board were all OST RLP 6.3v 1000uf with a small peppering of Teapo SH 16v 470uf capacitors.

                Even crap caps can be useful... such as blank rounds for prop gunfights.

                  Recapping Sony ICF-SW55 - verifying cap values
                  by proxneo
                  Dear reader

                  I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.

                  At the moment, I have selected replacements based on the following list of values:

                  3 x 470uF 10VDC
                  3 x 4.7uF 35VDC
                  4 x 47uF 50VDC
                  8 x 22uF 6.3 VDC
                  1 x 220uF 6.3VDC
                  5 x 100uF 6.3VDC

                  Which...

                  Different (lower) resistor values on PCB?
                  by Kobok
                  Dear Alls,
                  For sure it id a stupid question, but help me to understand. I am in a Dell 2007WFP revitalizing project - searching reason why not starting. Some resistors needed to replaced is is obvious. When I have soldered some resistors the measured (with multimeter) values were sometimes rather different written on them. I supposed these are wrong units so I desoldered and made a checking measurement and voilá the values is the same is written on. This happens only in case of a few resistors, most have the same values (+/- 10%) are written on it. "strange" SMD resistors =>103...

                  Here some measurements on HP Victus 16-d0500la, it might help someone, the values are on diode mode->mV and some lower ones on Resistance->Ω.

                  This specific laptop has an Intel i5 11400h + RTX 3050TI, the values are from a working laptop....

                  Epox EP 85 MVP3C-M - 3.54v Vcore regardless of jumpers
                  by kotel studios
                  Hi,

                  Recently I got an Epox EP-85 MVP3C-M board from scrap. After fixing the broken caps I powered it on without CPU and the jumpers set to 60Mhz FSB and 2x multiplier.
                  Sadly, Vcc3 was stuck at 3.54v regardless of jumpers. Vcc2 (Vi/o I think) was also the same voltage.
                  So, I've returned to the original configuration I got the board in - 100Mhz FSB and 4x multiplier. Voltages haven't changed at all.
                  What I've tried so far:
                  replace the original N-MOSFETs with beefier 60V ones for testing
                  Resolder the resistors near the Vcore Jumper block
                  Short Vcore...

                  MSI K7T Pro2 Ver1 - capacitors have higher values?
                  by Acerman123
                  Trying to fix this board, MSI K7T Pro2.

                  All Tayeh capacitors showed either as damaged or with uf values which were faf from what they should be so I have replaced them and all other capacitors except those big ones near CPU.

                  The motherboard powers on but doesn't post. My PCI bios code reader will most of the time dsplay some some kind of code if there has been no power to board for a while but I don't think those codes mean anything in this situation. If I power off the board and try powering it on the second time the code reader usually doesn't show anythin. Unplug...
