New ones have better high efficiency power supplies. Electronic
components are getting smaller and smaller increasing circuit density.
So of course new ones use energy considerable less. That points to
it also depends on product quality.
Stormin Mormon: I have not seen you in years. After you went ballistic
over what history now refers to as "The 100 watt Light-bulb Incident".
I had to take you off my news feed. That was a long time ago, so what
the heck...you asked a question I might as well answer it.
Yes, I was an industrial battery and charger service engineer for 38
years and do have both AC and DC clamp-on meters, they are somewhat
accurate, but my D.C. ammeter is a precision instrument and I prefer it.
BTW: To those here not familiar with the "100 watt" incident, I'm sure
there would have been a big article in the New York Times written by the
reporter who keeps all that happens on Usenet, on the front pages.
What a shame. I barely remember the light bulb
thread. Some thing about a guy who wanted to
return light bulbs to the store, and I commented
on that. Just can't remember.
Well, if Philo is so unforgiving that he filtered
me (many years ago) about light bulbs, he deserves
what he gets. Or doesn't get. Guess I won't be
buying his book, when it is printed.
I can simply change the display mode on my Cyberpower CP1500PFCLCD UPS to
see how many watts my system is using. It may not be absolutely accurate,
but close enough for my needs.
I have a Kill-A-Watt meter too, but haven't connected my computer to it
since I last upgraded the hardware.
