The program that reads the current electricity consumption of PC components

Question

Hello and welcome,

I am looking for a program with which I will be able to read the current electricity consumption by selected PC components (in particular, I am interested in network cards, integrated and installed as PCI cards).
It is also necessary that they run on Linux (probably it will be Debian). Using the system directory / proc, I can only read apm versions, which does not meet my expectations and is deprecated.

I am asking for tips / help.

And how is the computer supposed to know what and how much it is downloading?

Kasek21 · Answer

There is no such program.

What will give you such a program (as is) as the hardware probably cannot? :wink:

The voltage reading is sometimes sharply lame and I could use more info about the current ...
BTW: In the case of some newer graphics cards, you can think about it because there is some info, for example, about the power consumption of the GPU, memory, but it is still missing, for example, about losses on card converters.

Well, with the current electricity consumption a bit hard - the components take power from turning on the computer and the program is not always able to monitor / count.

There are only programs for converting the power of the power supply based on the components used, e.g.

Thank you for unambiguously answering my question.
However, now I have to consider the possibility of measuring power consumption with physical instruments. And here another question arises: is it possible to prepare a measuring station for the above-mentioned network cards so that it is idiot (student)-proof? Possibly I am asking for some examples of such positions. The element of interest to me is the network card.

You can measure the consumed current by connecting an electricity meter to a power socket (costs about PLN 50) and when it comes to the consumption of individual elements, it is probably the best solution to read the consumption from the technical specification and calculate.

I would like to see specific changes in the level of electricity consumption between the different baud rates configured on the network card. The solution given by my colleague is absolutely correct in relation to my last statement, but I would have to make some very inconvenient assumptions. More specifically, the differences that I would like to observe are in the range of 2-10W, and in relation to the variable load of other PC components, distortions may occur in this case.
I wonder if the network switches could not have a software function showing the current current load of individual ports. I am not talking about PoE-related issues, but since in this case this measurement works successfully, could it not be generalized?

I do not know if without a dedicated, I suspect that the home-made device will not work ...
Ev. connect the meter to the computer's power supply, and check for differences in consumption ... But the accuracy of this measurement ...
Ev. in the case of pci cards, usb cut the power lines and solder with the measuring system. Usb can handle it without much problem, but PCI ...?

From my information it appears that some servers have such capabilities. For now, however, the topic has been postponed to a more favorable period of time.

How can I read the current power consumption of selected PC components, especially network cards, on Linux (Debian)?
