Hmm I was going to say something about the Intel graphics too but the specs on the CPU only show Intel graphics and nowadays they specify a series like mine runs Intel 4600 series see pic.
If you gnat some way of telling see 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.
Run PART B: and click on where I have marked it will tell you just what graphics you have in the machine and more. Post back what you find there is another way but this is the quickest.
