PowMax power supplies are probably the worst products on the market, but they don't always go under their own name. Budget builders, such as most mom and pop shops, catch on to the name of one bad product but never seem to learn their lesson. They buy a dozen $15 PowMax units and start to see failures, so the buy a dozen $15 Brand X power supplies and unexpectedly get the same thing. And rather than stop there, they buy a dozen $15 Brand Y power supplies...and so forth and so on...all made by PowMax.
