Windows 2003 Server - power consumption
Does anyone know how to determine the power consumption of a server in watts, after all SW including OS is installed?
Does the power consumption increase when all programs are installed on the machine?
thanks

Software can cause power usage to increase if the software is using hardware which would otherwise be in low power mode. For example a database will cause a hard drive to use more power when it is being accessed. Aside from that the fact that software is installed will not increase power consumption.
You can buy devices that plug in between a device and the power socket which monitor how much power is being drawn and some UPSs have this built in. Failing that is down to guesswork. Some guiidance at http://michaelbluejay.com/electricity/computers.html but its very general

Keep in mind, that over time, if you continue to install applications on the server that make it do more processing or data access, the power consumption will probably increase. But once the server is up and fully configured, power consumption should not go up too much more from there. But there will be a difference between a sever with a lot of stuff running and a freshly imaged machine with nothing going on.
power consumption will rise and fall depending on your system processing load ( cpu / video / network load ). Modern OS usually try to lower that consumption using different power schemes based on the user preferences / activity on that system.
