PSU Monitoring Software | Tom's Hardware Forum
July 31, 2012 - All that I know of is I'm guessing what you're alluding to with the hardware, a Kill-A-Watt meter. I don't really understand why you won't even consider one, though. They're dirt cheap ($25 or so). Edit: Cheaper than THAT, actually: P3 International P4400 Kill A Watt Electricity Usage Monitor $17.84 (Oh look, a link 😛 )

Hi there. I’m wondering if anyone knows of a program like Speedfan or HWMonitor which can monitor Voltage levels. The issue with these programs is that they can’t do logging over hours - which is making them next to useless to diagnose a possible power supply issue. Cheers More on community.spiceworks.com

r/pcmasterrace on Reddit: Is there a way to monitor PSU Usage/Power Draw to see if your PSU is causing issues?
May 20, 2019 -
I am trying to rule out the possibility that my PSU is causing issues in a select few games I play. Specifically, causing game crashes related to (I think) DirectX. The specific error message is "DIAX ERROR DEVICE HUNG". If someone knows what causes this error message, then great! That will solve my problem. But if not, I have to start somewhere and I might as well start with my PSU as it is the oldest component in my build.
Anyway, back to the topic at hand. Is there a piece of software I can run on my second monitor or in the background to track PSU load and see if maybe my GPU/CPU isn't getting enough power, hence the crashes, or if there is some kind of issue with my PSU all together.
Again, the specific errors I am talking about are "DIAX ERROR DEVICE HUNG" or "DIAX ERROR DEVICE REMOVED".
Thanks in advance!

Corsairs upper tier psus show the psu voltages and all that good stuff, but outside of that you could see if your mobo manufacturer has any utilities you can run to see the board voltages, I'm not sure id trust any other monitoring software as they seem to do a lot of guessing.

Is there a way to take in account how much watts my pc consumes in a month and store them in a log file or a excell that i can look into? I am on windows 10/11, i know a software called hw monitor that displays a rough amount of instant power consumption but i don't know if i can store it in files automatically. Would be quite useful as i have 5 pc running 24/7 and i wanted to start taking in account how much electricity they consume, even if it is a rough estimate, without using external wattmeters.

Speedfan does the trick! It is possible to log data, if you perform the following steps:
Fist step: Enable the logging feature for the program
Readings → Configure… → Log → check “Enabled” → OK
Second step:
Now enable logging for the value you want to be logged:
Reading → Configure… → choose value → select checkbox on the bottom of the mask:
Hope it helps,
