That's the problem with using a single number to rate a PSU, when there
are actually 4 or 5 ratings that are required to properly spec them.
But the best one I ever heard was a gamer type who told me that his
computer runs "much faster" since he replaced his 500 watt supply with a
750 watt unit. My Kill-a-Watt says he is drawing about 180 watts :-)
I think his situation is in the realm of the psychologists, not the
technicians.
