My partially-recapped L&C 450W PSU

Newbie2, maybe it would be nice to know what are the ampere rating for those +5v and +12v rectifiers on the secondary side... Btw i also do recapping for many L&C PSUs but yours seems to have "cheaper" quality..

I'm not going to take it out one more time, since the mounting holes on the front are becoming enlarged (from all those removals and installations ). It's a typical Y-B200ATX type L&C power supply, maybe somebody here has one.

Re: My partially-recapped L&C 450W PSU

I just did a check-up on the L&C power supply today. It's been over a month since its recap, and I checked to see if there were any problems. I fixed a few weak solder joints from the recap, since I now have more experience in soldering than I did before. I added an additional Nichicon 1000uf 6.3V cap in an empty place for an 8MM radial electrolytic cap near the other one I had put in before. It's the cap that's closest to the fan in the Y-B200ATX-based L&C power supplies.

But one thing caught my attention. During the solder joint checkup I found a bad solder joint on the Rubycon 1000uf 16V 10MM YXB cap I placed a month ago. I tried to correct it with no good results. I took the Rubycon cap out and found dried brown liquid (probably electrolyte) leaking out from the bung of it. I replaced the Rubycon cap with a "drang con" 1000uf 16V 10MM cap I had in my jar of caps, and I could make good solder joints from it.

Since the YXB series is an older discontinued series of Rubycon capacitors, and Rubycon's current products have improved, I still believe in the quality of Rubycon products.

Don`t forget to handle the leads with care. If you bent or stress them to hard, the bunge itself could easily be damaged.
I have to admit, that i personally have misused many caps from that point of view, but up to now i was lucky.

YXB was a good low impedance series about 15 or 20 years ago. But I suspect current applications are a bit to challenging.
