For malfunctioning hardware the best testing is swap testing.

There is no definitive software test that is reliable for PSU.

Hi,
The kernel power event ID 41 error occurs when the computer is shut down, or it restarts unexpectedly. W If the computer was not shut down cleanly, a Kernel Power Event 41 message is generated.
Computers that are not receiving enough power can have subtle symptoms like graphical downgrades to obvious extreme symptoms like being unable to turn on.

Please note: Information posted in the given link is hosted by a third party. Microsoft does not guarantee the accuracy and effectiveness of information.

Here's a couple things you could try:
Try a different power bar.
Unplug everything but the PC from that power outlet to be sure the problem is the PC itself.
Use a power supply tester to see if the PSU is providing the correct voltages.
If you have a spare PSU, try running the PC from that one instead.
Run a temperature monitoring app that records temperature to a file. Some CPU models can cause an instant system shutdown/reboot if they get too hot.
Try to run a live OS from a usb stick without storage drives and just the bare-minimum hardware connected. If the problem still occurs then you at least narrowed it down to your CPU, motherboard, RAM, or PSU.
Run a CPU & GPU intensive stress test to see if you can reproduce the shutdown quicker. (Will help you narrow down the problem & save time troubleshooting.)
Hope above information can help you.
