Toms Hardware has done tests. And Paul Marwick included a site with
recommendations.

From my reading: Most of us need less capacity than we think. With
exceptions for gonzo gamers and those who are driving serious audio
cards and speakers thru their 'puter boxes.

Which PS? HOPELESSLY complex. Pick the sect you want to join. 

Don't agree? Well, now that you've picked the PS you like, tell me what
the lifetime cost, including electricity costs is. For all we know, the
$100 PS may save you $30/yr over the $50 model in operating costs. Or
cost you an additional $30. 

One more thing. If your PS will be connected to an UPS, how much of what
you've paid for robustness to line voltage variation and resistance to
noise was unnecessary?

    Of course, I did not know that these brands were "advertised 
heavily", but the extra cost of advertising may be only a few dollars 
per unit if their volume is sufficiently high.

    Sorry, I don't see why a nominal spec is an important comparator? 
I  would think that the average & variance in outputs plus the mean
time  between failure would be more important indicators.

    Okay, but to get back to my original question, which brand & model 
of used PSUs should a person consider?
