Again, theory vs. practice.
Reality standard for so many generations that short circuit damage says a human is dumb stupid or in denial. Every layman can do the test. A supply that fails is immediately bought back by the retailer. A test so easy that no 100% defective supply should be in service. Unfortunately, we often call them cost controllers, bean counters, spin doctors, cheapskates, finance people, or uneducated. That is the reason why a shorted supply destroys itself.
All computer assemblers must meet FCC, UL, and other standards. Even most A+ Certified Computer techs don’t know that. And have virtually no electrical knowledge. So few are ‘voting’ responsibly. The domestic market remains ripe with scam supplies. A problem completely traceable to a person – not to hardware.
If a supply does not sell for at least $60, then one immediately has reason to suspect. That does not say that a $60 supply is sufficient. The second sentence so important because so many computer techs have insufficient technical knowledge. Will assume the first sentence says a $60+ supply is sufficient.
If a supply does not come with a long list of numeric specs, then an informed consumer immediately suspects the worst. ‘Voting with your wallet" is what free markets are supposed to do. But only if the consumer demands facts with numbers. Unfortunately too many computer 'experts' are so technically naive as to encourage all layman to be uninformed. And to stay uninformed.
Theory is ‘voting with a wallet’. It should work - in theory. Reality is what hardware must always do. Every layman can identify 100% defective supplies that still boot a computer. Simply short its outputs. If the supply fails, then it was always defective. And may also destroy other computer parts – motherboard, disk drives, etc. That is not theory. A requirement that most computer techs do not even know to, instead, dump inferior computers on naïve consumers. Who then deny they – not hardware – are why failures exist. May even deny reality using bogus ‘theory’ accusations.
The market has inferior power supplies because most computer techs do not even know how electricity works. Defective hardware directly traceable to that human failure.
