    Can the symptoms this person is reporting be a sign of bad caps in the PSU?

    http://www.ocforums.com/showthread.php?t=433846

    Said that the PSU was fine for at least approximately 1 year and that afterwards, the +12V rail spikes up to at least 13V then shuts off.

    Possibly... the caps in them are all Teapo, and the PSU has cooling issues with the intake fan blocking all ventilation to the secondary side.

        Aye

        The intake fan on these is fitted right up against the secondary heatsink, leaving perhaps a 1/8" space on the extreme edge of the fan to get air into the secondary side. As one might expect, the secondary side then gets hot and since the fan controller is on that heatsink, the fans start spinning up to very audible levels.

        On mine, I moved the fan to the outside of the PSU case - it runs much cooler and quieter that way. At the moment, the exhaust fan is barely pushing any air at all, and it's nice and cool.

        Edit - forgot to mention the secondary side has a huge coil shoved right up against the 6800uf secondary filter caps, and the heatsink unfolds right overtop of the whole thing - with no good ventilation, it just acts like an oven and cooks everything in there.

          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).

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

          Repair of Sign WiFi Smart Plug PCB: SA-P302A v1.2 due to bad caps - with schematic
          by Per Hansson
          I have repaired a Sign WiFi Smart Plug with model number: SNSM-WASINGLE sold by Spares Nordic AB in Sweden.
          The fault condition was that the device gave no signs of life: pressing the push button did not cycle the internal relay and the blue LED did not come on and it was not seen on the WiFi network.
          The fault was very simple, capacitor C3 on the PCB with writing "KSJ" and "LOWESR" had literally blown its top off, after replacing it the device works fine again!

          As I find linear high voltage regulator designs interesting I drew up the attached schematic...

          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
          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...

          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,...
