The newer Asus psu's have an actual LCD screen that displays all that kind of information in there. As to how useful that is in current cases is another argument entirely. Answer from theonlyone38 on reddit.com

PSU with power monitoring - Power Supplies - Linus Tech Tips
May 21, 2019 - I'm looking at getting a PSU to run a test bench, and want some kind of power monitoring and reporting. These PSUs also connect to the PC by USB, and can report info about power usage. Use cases will probably cover single CPU + GPU in competitive overclocking (sub ambient cooling, not LN2), as we...

r/buildapc on Reddit: PSU's with monitoring options?
October 31, 2021 -

I have a couple of Corsair PSUs that can be monitored (over USB) for power usage and while I am happy with it as a PSU, I am not too charmed by Corsair Link, iQUE, etc. In fact I can't really figure out what is their recommended solution, and what is being depreciated, how to configure things without it constantly being a PITA about upgrading, etc.

I also find it odd that I can't seem to find many other vendors with that kind of monitoring capability - seems like ThermalTake has it, although I couldn't be sure. Surely Seasonic must have something? Ideally, I'd like something with just a device driver that can be picked up by HWInfo or something.

I guess USB is the only viable solution today, though it seems like a bit of a waste of a socket, shouldn't there should be some kind of wireless IoT protocol for motherboards yet for this kind of non-critical low bandwidth infrastructure?

Anyone have any suggestions for a decent PSU with a lightweight monitoring solution?

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!
