*I measured one of our "standard" desktops, a Dell Optiplex GX280 in
the
small form factor case with a 3 GHz P4, at 90-110 wt depending on what
you're doing. Mostly hovered around 95-100 wt during normal operation.
**I've measured PII 400 MHz systems at about 40 wt. **My HP
Workstation
xw6200 dual Xeon 3.4 (800 FSB) desktop takes a steady 250 watts, with
my
dual Xeon 3.0 GHz (400 FSB) desktop taking around 225.
In other words, it can vary a significant amount depending on what kind
of machine you're talking about. I'd imagine probably not something as
old as a PII, but not something as powerful as a dual Xeon. Hence,
somewhere between 40 and 250 watts. :)
My 20" Dell LCD takes up about 45 wt, a couple of our 17" LCD's around
30 wt. Neoware Capio 620 thin clients use 9 watts under normal
operation.
Dell PowerEdge 2850 dual Xeon 3.6 GHz servers with two 15K RPM SCSI
drives and dual power supplies take a pretty steady 250 wt under about
a
25% system load, and use the same amount of power whether you have one
or two power supplies plugged in. They briefly jump up to about
450-500
wt at power on though, with all the fans screaming full blast during
POST.
I haven't tested any CRT's though.
Why not just pick up a cheap meter and test everything yourself? I've
used one of these in the past, they seem to be more than accurate
enough
for things of this nature.
