[...] When VA and
Watts are both shown on an appliance tag, and they're different
numbers, VA is used to indicate peak, and Watts is used to indicate
the average draw; the amount of power consumption you're most likely
to see on your electric meter if the thing runs all of the time.

This is simply not true.


Maybe you came in late. I'm talking about the power consumption of the
appliance (the computer), not the power rating of the UPS. The rating
tag on a UPS or even a power stip is *not* the same and it's *not*
what I'm talking about, although it should give both and in and out
ratings. You need to know or guesstimate the power consumption of the
"appliance" to determine the rated-size of UPS you need to buy.

Wondering if I've just dreamed this, I checked various *appliance*
rating tags (without pulling things out or crawling behind something)
and only found one (on a TV) where VA and Watts are both listed:

120 VAC 60 HZ 450VA 240WATTS

Now, how do *you* interpret that?

(Quite a few of the ones I looked at just show Volts and Amps and
expect us to know how to multiply.)

On to better things.

Good plan.


Executing plan....now....now....now
