PSUs from reputable names that i've seen TOO much failures to be normal:

Antec Truepower : 430W version of this series, tens of failures in the last 2 or so years, not average imo

Antec Smartpower : No matter wattage, i would immediately change this from any case i get with it. All of mine are dead and alot of my clients have been hurt from it as well, from simply not working to smoking up the place and carrying components with it or simply chirping to death.
