I was wandering if (most common) motherboards provide hardware capabilities for measuring the exact power, expanded by the individual components - CPU, RAM, WiFi, etc.
As voltages are read and directly available e.g. in BIOS, I reckon that similar interface may be provided for the power consumption as well.
Searching Google for fedora18 power optimization pops up a nice guide. Inside, PowerTOP is recommended and it's use is described. The program "is a software utility designed to measure, explain and minimise a computer's electrical power consumption", and this is as close as it gets to answering my question. Voila.

I'd like to buy a multi GPU motherboard but wanted to separate the workloads separately on each GPU using windows
I know you can select a GPU for high performance in Windows 10 but that's not separating tasks/workloads
I.e. one GPU can work using one program and another GPU using another program without sharing workloads
Is this possible?
This kind of explicit multi-GPU management is supported by DirectX 12.

I want to use my main PC and my secondary PC that I don't use often at the same time but have only one monitor
I don't want to buy a new monitor just for this though, if you have any idea how to render both of the computers to the monitor at the same time please answer
Picture in Picture (showing both inputs at the same time) is a Monitor feature. Unless your monitor's software is capable of doing that, there is no possibility to achieve what you want.
Some newer monitors might have the capabilities of doing what you need, depending on the price range.

Short question and hopefully a positive answer:
Is it possible to create a virtual CPU that consists from multible real cores?
So lets say you have a 4x3.5 GHz CPU, can you create a vCPU that is 1x14GHz ?
Why do it?
If there is a software which is heavily CPU using, but can just use one thread, it would boost up the program.
I am not very advanced with hardware tech, but I guess there is no way to do that.
Thanks.

No. As the expression goes -- nine women cannot make a baby in one month.
Each instruction executed by a virtual CPU can potentially be dependent on anything that previously happened on that CPU. There's no way to run an instruction (or a group of instructions) before all of the previous instructions have been completed. That leaves no room for another physical CPU to speed things up.

Is it possible to have both CAN standard frame and CAN extended frame coexist on a single CAN bus ?
can bus protocol allows this to happen?
The spec allows it and it is also common in modern bus systems. If I remember the spec correctly, every CAN-Transceiver must at least tolerate the extended frame format without disturbing the bus.
So it should work as long as you don't have some ancient hardware on your bus.
I have not done this yet, but to my knowledge it is possible to mix standard and extended frames as long as all CAN bus participants evaluate the IDE bit. Which means that all(!) CAN bus participants must be compliant to CAN 2.0B.

Does an USB-Y-Cable (often found for USB 3.0 devices, for better backwards compatibility/faster speed?) like the following just splits the power or also the data? The second USB-male-plug has a thinner cable, so I think something is missing there.
I didn't find an answer on google.
Power only. There is no way for two devices to signal serially without a hub. It is however possible to have a very small hub. So, unless your "y" splitter is also a two port hub; It's power only.
