    Antec PP-303X

    Here's another Antec that fried. I'm not sure if it was caused by bad caps but it is loaded with fuhjyyu caps. I have since opened every PS and replaced all on the low voltage side with quality caps from Digikey. Voltages when monitored in the BIOS are much more stable now! Should the 22uf 50v caps be replaced as well? Some of the threads on this forum indicate these are also the cause of problems.

          If that's a a 300W P/S, those are very decent sized heatsinks (How often have I said that in a post?). What is that fried daughter card, a temperature-controlled fan O/P?

              later models had the nice heatsinks and glue (how am i supposed to to service this junk or inspect the caps) and of course a lot of teapo etc

                  All of the Antecs I've seem to be well designed with beefy heatsinks etc. Their choice of fuhjyyu caps kinda negate the decent engineering however.

                  I think this is the fan control circuit. Not sure what the blown daughter card's function was except scaring my wife when it blew up hehe.

                      I think the fried board is for the +5V standby rail, if I am correct, from the size of this board.
                      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

                          correct.likely had the chopper short and blew up the parts leading to its gate.

                              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=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."
                              ...

                              Picking caps for Antec SU-380
                              by ajdrenter
                              In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
                              https://www.badcaps.net/forum/showthread.php?t=14159
                              It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:...

                              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,...
