Hi all,
Was wondering if any of you know about a tool to measure the number of
watts drained by a machine. Trying to make my machine as
power-efficient as can be.
Thanks in advance.
you need ampere meter [1] ..connect it in series[2] with your system
(assuming you are using desktop ) and get the reading on meter
[1] http://en.wikipedia.org/wiki/Ampere-meter
[2] http://www.allaboutcircuits.com/vol_6/chpt_2/4.html
This approach neglects the influence of idle power. Some better
PC power supplies have near to zero idle power, but cheap power
supplies show large idle power even nowadays. You should better
use some kind of wattmeter. Such a tool should be available
for about 10$ from any local electronic discounter (here in Germany
from Conrad Electronic).
Joerg
Thanks for all your replies.
