How to see the voltage of the power supply under centos?

Question

CentOS

Good day.
There is a task to check 3.3V, 5V and 12V on a PC with CentOS on board. There is no GUI, only bash.
Under Windows, there is AIDA64 software, which does an excellent job with this task. I immediately tried lm_sensors and inxi, but alas, they also did not show me what I was looking for. Although I do not rule out the fact that I did not read the manual well, or that I am crooked.
I ask to prompt, in what direction to dig?

Answer 1

To measure the voltage there is a Voltmeter (multimeter). What is the point of looking at a computer if, in the absence of any voltage, you will not see anything.

Answer 2

Look in this direction

In addition, there are likely specific sensors for your system, indicate the motherboard number and search for smbus keywords
By the way, look at the list of sensors here, it will become easier to search for the console
