Am looking for a reliable cost effective ATX Power Supply.

"Lack of protection circuits, low efficiency, and bad build quality
were major points of criticism." Like most PC hardware seems
important to do your homework.

Hope the protection circuits work. Do not want an explosive or fire
problem so am especially interested in power supplies that have
survived catastrophic events.

You may want to check JonnyGuru.com and HardwareSecrets.com for
recommended models and brands. Among the best manufacturers are
Seasonic, Enhance, Win-tact, and Zippy/Emacs, but also good are Delta,
Enermax, and Fortron-Source/Sparkle. These may be sold under various
brands, like Corsair, Thermaltake, PC Power & Cooling, and Antec, and
each of those brands may be made by several different companies. Some
manufacturers produce a wide variety of quality, with the better
companies simply substituting inferior brands of electrolytic
capacitors in their cheaper models (Seasonics may use OST capacitors,
Deltas may use Ltec), meaning the power supplies will work fine, only
they won't last forever because those capacitors will rot. Capacitor
quality matters a lot. For example, I have an ancient TV that's
needed only 2 of its Japanese capacitors replaced in 35 years, while
the digital converter box on top of it has had most of its Chinese
capacitors go bad in less than two years.

Even the very worst power supplies have protection circuits, only the
protection doesn't work fast enough to prevent damage.
