    I'm not saying that failures earlier than that are impossible, but I haven't found it to be overly common (except in cheap PSUs where they run hot and are overtaxed). On well designed, cooler running PSUs, I've only ever seen maybe a dozen rectifier and transistor failures vs hundreds of units with bad caps.

    Well, you can tell by the last line in my sig my position on heat - so I agree about cheap, hot running PSUs.

    Overtaxed is a different issue, however, as that is the computer assembler's (or upgrader's) error for using an underpowered PSU. I don't believe overtaxed/underpowered abuse should be a factor here.

    The fact of the matter is, a well designed PSU today is NOT likely to use inferior caps and should be expected to last many years, if kept clean of heat-trapping dust, and not over taxed - and not subjected to excessive or extreme power anomalies.

    That is true. I was referring more to individual components being overtaxed, rather than the PSU as whole, like those cheap liar-labelled "550W" PSUs with 10A rectifiers on the 12V output which get used in newer PCs. The average system builder has absolutely no clue that their "550W" unit is only a 200W unit in disguise or that it's meant more for Pentium 3/Athlon XP systems. It's in cases like this that I often find PSUs with burned out silicon components.

    The primary cap only works at 50/60 Hz, hardly any heating compared to the secondary that work at tens of kHz

    I find recapping normally well worth the effort.

    Take it easy on the necroposting, please.

    Sorry, but I thought recapping was still of current interest

    It is. But you've bumped a number of rather old threads. While this might be relevant, just keep in mind that when someone typically does this, they end up being a spammer.
