*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. **http://www.google.com/search?q=kill+a+watt *

*Subject:* [THIN] Anyone done calculations on energy saving for thin client devices ?
Things I need to calculate.
Existing power used by PC and CRT monitor versus a thin client with LCD screen.
Need to take into account heat output power consumption etc.
Anyone got anything they have either done themself or seen online.
Send offlist if required.
Thanks in advance
