What we REALLY want, of course, is a good power supply, cheap.
Getting a good power supply, expensive, is not that difficult, as, unfortunately, is getting a bad one cheap, or even a bad one that isn't cheap.
My own example, and I hate to tempt fate...
CASE PSU is a "Maxpower" 300w unit - it has survived a few years, the fan failing (yes, it seems to have thermal shutdown!), been replaced with a QTEC 450w (taken back due to voltage inaccuracy) and a no-name 400w unit (became unreliable).
I later faound a review of QTEC's 450w and 550W, and they did NOT like the 450W - the 550W was a different design, not just a few uprated components, and a lot better (a decent "general purpose" PSU, though not up to the demands that a better name 550W would handle)
If I found a bigger Maxpower unit now, I'd buy it!
One name that does drift into memory - TAGAN - they seem to be well regarded, but not as expensive as the overclockers favourite names.
I also have a liking for the dual fan, or large internal fan style of PSU.
A final note, if you are at a real life store or computer fair, the heavier the PSU is, the better it is, unless one is aluminum and the other is steel - more meat in the heatsinks and casing, is definitely a good sign.
