The batch of bad capacitors that affected a generation of computer

There were lots of cheap 'no name' brands (as I call them) affected.

They were all low-ESR caps designed for switchmode power supplies.

Badcaps.net gives a partial list of brands affected IIRC. You're unlikely to have
ever heard of any of them unless you spend a lot of time looking at PC
motherboards.
