Howto make your own systen power analyzer

Ultimately, everyone would be best served if, in addition to reporting total power at the wall, power consumed by CPU, GPU, and motherboard were analyzed as well. This way both the total system power, as well as where the power is parititioned, can be rationalized and systematic errors eliminated, at least those introduced by the PSU itself. What you will read about here, today, is a nifty method for not only measuring power on all the voltage rails but also how to build this system economically. The article will conclude with some simple experimental results that looks at different software commonly used to produce a load, and show that different results can be obtained simply by the software one may use.
