Quick way to estimate power usage?

[Special K]

Does anyone know of a way to estimate computer power consumption, based on the number and type of components that are in it?

The easier way would be to use a clamp on ammeter (borrow one if you don't have one) and put it on the cord going to the PSU. From there it's a simple calculation as to what your ACTUAL power usage is.

You can check the specifications for each and every component in your computer and add it all up to get an idea of how much power you might be using. A while back someone posted a link to a site that had a calculator to help figure out an general estimate, maybe someone remembers what it was.

The easiset way (and most accurate) is to buy a mains power meter - these are readily available for less than $30.

You just plug in the device under test, you get measurements of true power, current and voltage, energy consumption and estimated cost.

Power consumption varies substantially depending on CPU load, optical drive spindle speed. etc. Monitor power consumption can vary significantly with refresh rate and image brightness.

has anyone done this? can they post their findings (system, consumption under load, consumption when idle)
