My mistake.  This isn't the article I thought it was.  It turns out that
the article I'm thinking of was done in 2002, and it seems as if Tom's
Hardware has been doing regular reviews of PS since.  The original
article was interesting in that it listed several power supplies that
burned out well below their advertised voltage:

I recommend the more recent one as a guage for what manufacturers you
can trust.  Frankly, if you're only spending $50 on a 400W, you're
probably getting a piece of junk - although Fortron has been rating
well in Tom's tests.
