I've been looking for a way to estimate my CPU power consumption and, of course, I've found that on the forum.

Here is the link to this great post by Idontcare : https://forums.anandtech.com/threads/power-consumption-scaling-with-clockspeed-and-vcc-for-the-i7-2600k.2195927/

I've more or less follow what he has done and apply it on my computer.

First I held the operating voltage while increasing the clock speed. I've done it for lots of voltage.

Here are my results :

As you can see, the consumption is linear with the clock speed (I've avoid the clock speed higher than 3300 MHz for further analysis). I haven't represented the equations on the graph so it can be clearer.

Still following Idontcare's work, I've plotted the interception with 0 GHz for each voltage.

Here is the graph I got :

The result is supposed to be linear and .... it's clearly not here. The tendency equation on the graph is 2,2*Vc^6.75+65.

Could someone help me with that ? What's wrong with me ?

Btw I'm working on a AMD FX 4300 and my mb is a Crosshair V Formula-Z.

I'm also sorry for my shitty english level, I'm French. Please pardon my French ...
