Don't these results give at least some idea of how close to TDP real usage might come? Of course, measuring at the mains, you have to take into account the efficiency of the PSU, and such things as number and power consumption of drives and fans. Victor's assignment of 10 w for drive and fans seems a little conservative to me. But then, I have a bunch of spinning things in there, both drives and fans.

It still seems that such measurements can make for more informed estimates, especially if you can narrow down which parts are using what power,
