    Matsonic MS8308EP Bad Caps

    Got 9 bad caps on this Matsonic socket A mobo before she decided not to post.





    All caps are made by G-Luxon

    gonna recap it?

    not recommended to leave it until she fails to post, better to recap as soon as you see some bulging/leaking.

      Looks like it's the same board as PC Chips M810LMR and ECS K7SEM. You're lucky that the mosfets are not burnt (or at least they look OK).

        The FET's have been getting hot, look at the discoloration on the PCB. I hope that they are still ok. Hopefully it will be worth a recap. Good luck!

          Yeh, the back is really discolored. If it worked, it will be worth $20 or w/e in caps!

            based on my experience the m810lmr boards are not really worth recapping. socket A, int. everything, picky about video cards, unstable b/c of chipset heat issues. use the $20 to buy yourself an 8rda off ebay.

              hmm Ill calculate the cost in caps and see if I cant just replace them with some used ones I have laying around. I will just be using the mobo for a folding rig anyway. Nothing workstation or anything of such.

                Re: Matsonic MS8308EP Bad Caps

                okay, but make sure the used ones are of good brand and low ESR. btw I meant 8rda3 in my last post.

                  Yeh it was actually a customers that they brought to me after she wouldnt post.

                  The board is now mine and its just a crapper that as I mentioned Ill just be using it for folding. So, obviously I dont want to put much if any money into the damned thing. My question is, it had those shitty G-Luxon caps. They were rated at 2200uf 6.3v and there were 12 of those and 4 chokes. Thats honestly the most caps and chokes Ive ever seen for a cpu supply curcuit ever and this is a low end board! Would it be alright if I replaced them with 1500uf caps (low-esr of course) that I took off another board? This board will be at my house so I can watch it and it honestly doesnt even need to be 100% stable.

                  WOuld that be fine?

                    Re: Matsonic MS8308EP Bad Caps

                    1500 would prob. be OK. What are chokes?

                      Inductors. They form a filter network with the lytic caps.

                        PCB layout is almost identical to PCCHIPS M810LR v8.0. / ECS K7SEM v3.0a / Amptron K7- 810LM Motherboard.

                              Sure! Just kind of an update too, Ive been running this mobo with the 1200mhz duron everyday 24/7 folding (100% cpu load), and it still is running rock solid!

                              As for the brand of caps, they were kinda mixed , just used what I had around since its just a folder mobo. They were samsung, choyo, and that other brown colored one (cant remember name) that comes with DFI mobos.....

                                from what you used, the sanyo (green) are good, the chemicon (brown) are good, the choyo are shit.

                                      HaHa,

                                      I just found this thread and I have the same Matsonic (it is a 266) and was wondering if I could replace just the single 2200/6.3 that is swollen. There is no discoloration of the board @ the FET's which is a good sign I guess!

                                      To see that this mobo works w/a vast assortment including 1500 is great news.

                                      Due to the low value of this board (are all EP's 266's? is the 266 really worth much more?) I'm going to use parts removed from other mobos.

                                      I have an Abit KT7E that has a few slightly bulged caps and I'm going to get new stuff for that one. However, I don't think I'm going to replace all the caps. Since the 2200's all look perfect. (All caps are Jackcons and there are 6 types: green w/gold "LOW E.S.R.", black w/gold "LOW E.S.R.", and black w/white.

                                        Don't replace just the one - the other will go bad soon so you'll have to replace them later anyway. And there's a risk of the MOSFETs shorting on these boards with bad enough caps...

                                          by momaka
                                          I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                                          For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                                          Heathkit IO-4205 Power Supply Caps
                                          by eryjus
                                          Hello,

                                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

                                          Identifying caps on an old Zoom 9000

                                          Hello!

                                          I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                                          The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                                          I have studied the board and...

                                          Help with switching power supply caps
                                          by captain150
                                          I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                                          I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                                          Gigabyte GA-6OXT :: caps question
                                          by Foetuss
                                          Good evening

                                          I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                                          Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                                          But I was also suprised about the bigger boys, which are 330µF 25V.
                                          Could it be they used 25V caps because they were cheaper / available at that time?...
