    Supermicro 370DLE with bad caps

    I recently acquired a Supermicro 370DLE motherboard. I got it knowing it was not working, and the seller indicated he didn't know what was wrong... I figured for $15.00 I'd take a chance with it.... It is full of caps marked with the brand of \"NRSY\"....

    Lone behold when it arrived, there are several 1000uF caps bulging at the seams (obviously bad)...

    I've replaced them all with nice low ESR Sanyo's....





    KC8ADU, you mentioned in a previous post in this forum that you have had one of these board with the crap cap plague, I was just wondering what the symptoms were, and if you were successful or not... The seller indicated that the board wouldn't POST, and just beeped at him... I have recapped it, replacing a quantity of 17 - 1000uF 16v low ESR capacitors, and a quantity of 2 1500uF 10v low ESR caps.

    Sadly, I'm unable to test it right now... I have plenty of CPU's and ECC RAM... However, I don't have a PCI video card, so I have no way of testing it at the moment... Yeh, I know that's pittiful.... I'll snag a PCI video card in the next day or two to find out... I was just curious about yours...

    Let me know!

      mine is a 370dl3
      have a pile of p3dm3 and p3dlr too i just got.
      i recapped the 370 and it works fine.
      the nrsy caps had vented worse than yours.
      i didnt even bother to test it.
      recapped it just like an antique radio.
      all caps must go

          It's already been recapped... I don't have a PCI video card to see if it's a success tho... I pulled 8 bulged caps, the rest appeared normal, but were replaced anyway... 3 of the 8 bulging caps splooged electrolyte gunk all over the PCB, so I'm sure it was a problem... Should all be cured now...

          Guess I gotta track down a PCI video card... HEH...

                  150+ SM boards?! Strangely, I haven't seen many of them for recapping... This one was the third I've recapped, the others were an older dual P2 Xeon, and a dual standard P2...

                  However, the VP6 count is up to 98, the KA7 count is 34, the hodge-podge of others is well over 100...

                  Just outta curiosity, what do you see the most of?

                          just got 6 more sm boards in for recapping.
                          they were bought less than a year ago new.
                          these are just unstable.caps look ok but the scope says they are shot.
                          vcore shows 1.3v p-p!
                          sop here is now to change all nrsy caps on sm boards then test further.
                          customer brought a new piiidm3 in to recap before it gets installed!

                              Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                              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).

                              https://www.badcaps.net/filedata/fetch?id=3591771


                              https://www.badcaps.net/filedata/fetch?id=3591772

                              It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                              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."
                              ...

                              by Paxman_Swede
                              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...

                              HannStar Hanns-G HC194d LCD monitor repair
                              by momaka
                              Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                              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,...
