Power measuring of PC components

[timo]

Dear members,

I'm looking for a measurement system for the internal current wires
of a personal computer to approximate the power consumption of each
component (e.g. the disk system, cdrom drive...).

Unfortunately my knowledge of electronics/physics is restricted to a minimum.
My first research leads me to some hall sensors, which should make it possible to measure each internal dc wire without the need to unplug any wires, for example something like this: http://www.phidgets.com/products.php?product_id=3500

Is it possible to to use this kind of sensor for my purpose?
And what else do we need to log the data of multiple sensors with a PC?

Or is the idea of measuring with this hall sensors totally wrong?

I'm looking forward to your opinion.

Best regards,
Timo

It should be possible to do it that way.
The one you linked to can only measure AC and so is unsuitable for your application. Use this instead.
You'll have to cut the wires you want to measure however. But I'm positive there are clip-on options. One feed-through alternative is the CSNB131.
If you want to log the data on a PC then you could use something like this.

Thanks a lot for your reply and your suggestion. I'll try it this way.

Timo
