Ok mate two ways you can use this
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
IE
12v = 11.4v min to 12.6max
5v = 4.75v min 5.25v max
3.3v = 3.135v min to 3.465v max
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
Use PART A: or you can do it with one of those cheap digital multilmeters
See this for where you find whet the volts you should be getting Power supply unit (computer - Wikipedia) scroll down to see the 24 pin plug cable clours these reflect what you shoud see on all the other connectors eg the GPU power connector.
Just be aware the volts must fall within those figures I quoted above otherwise the machine will not work properly or if at all and can damage certain components. As in that link test the POWER_GOOD signal at pin 8 (grey cable) must be on before the machine will even start it is safety feature of a PSU circuitry to protect the board and components.
