Paranoia checks wouldn't be necessary if PSUs weren't commonly made for
cheapness. It takes no more than a few comparators to check the voltages and
even that's "too expensive" or "impractical"... I've seen PC PSUs that use a
555 to generate the POWER_GOOD signal (they literally wait a second before
asserting POWER_GOOD, even if the power lines are well out of spec)!
