I had a good PSU, a 300W Antec (actually CWT "B" -- same thing) fail,
but that was because its capacitors were involved in the Taiwan
counterfeit electrolyte scandal of 2-3 years ago. Actually I wasn't
having problems with it but just happened to have it open and noticed
some bulging caps. OTOH bad design caused failures of my 300W Codegen
(10-16V capacitor had 50V spikes across it) and 250W King Case (blew a
MOSFET when +3.3V rail was shorted).
www.hardforum.com/showthread.php?t=824361 is a thread about PSU
failures, and more cheapos, like Deer (Codegen's parent co.), seemed
to fail more than quality Antecs, Fortrons/Sparkles, etc.

I bought a free-after-rebate Soyo case w/ 300W Soyo/Key Mouse/MaxPower
PSU from Fry's and substituted a $15 300W Fortron/Sparkle. Why was
that foolish? The Soyo PSU had much lower +3.3V and +12V amp ratings
(probably not enough for a mobo that uses +12V for CPU power), its fan
was noisy because it wasn't temperature-controlled, and it had no EMI
filter (drowned out AM radio and TV ch. 3). Fry's often features
cases for $5-15 after rebate, but their PSUs usually seem so bad that
I wouldn't dare use them, except for spare parts. Still a person
could sub a quality PSU from NewEgg for $25 (Hi-Q, PowerQ, both made
by Fortron) and still come out ahead.
I expect Fry's to have another really cheap case-PSU deal either on
11/26 or 12/26.
