So how big need a power supply be in most every ATX computer today? So many have suffered failures. They had no idea why the failures happened. So they use a Tim Allen concept of "More Power". That result alone is sufficient (to them) to prove that ATX computers need 400 or 500 watt power supplies. They need not even know what the original problem was.
What do engineers put in their (equivalent) computers. Brand name computers do same with only 200 and 300 watt supplies. So why the 400+ watt solutions? So many computer experts cannot even first do the numbers or even make basic measurements. They have insufficient knowledge to know why failure happens. Furthermore, without basic knowledge, then that 'expert' doesn't even demand specifications. Many of those 400 watt power supplies cannot even output 400 watts. Of course. Manufacturer didn't provide written specs for good reason. He is not selling to computer 'experts'. He is selling to someone without sufficient background information. A power user who calls himself an 'expert' only because he can replace a power supply - and not know what the problem really is.
Shortage of basic computer knowledge is rampant where domestic computer builders select power supplies. Urban myth rather than basic technical knowledge often decides. Then when those supplies cause problem (fail, damage motherboard, cause intermittent crashes, permit surge damage, etc), then the ill trained builder solves the problem with a bigger supply - "More Power".
It is a shortage of basic knowledge even among computer power users that demonstartes only one reason why even computer technical support jobs are better performed overseas. Just one of many reasons for outsourcing. Again, we graduated less engineers every year since 1990. Who then will do the innovating? More reasons to outsource - or why we need more immigrants. A problem commonly demonstrated by so many domestic computer 'experts'.
