OK. both sides are well stated. |

Amp meters are less than $50 USD. They clamp around the |
14 |
power cord, or any wires inside the computer you can fit |
15 |
the "clamp" around. |
16 |
|
17 |
So make your choice, based on actual measurements? |
18 |
That's how an EE would make a decision on how |
19 |
a given processor or software setup actually effects |
20 |
the power consumption. REAL DATA. |
21 |
|
22 |
Note, some of the fancier meter's have an integrator function |
23 |
where measurements are taken frequently over a time period |
24 |
to get an even more realistic picture of power consumption... |
