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

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/buildapc on Reddit: Value of PSU Monitoring Software (Corsair Link)?
July 20, 2018 -

Thanks in advance for your help.

I'm updating my PSU with my most recent build (first in 9 years) and see that now software-monitored PSUs are a thing (along with fully-modular cabling...thank God). I'm struggling to see the utility, though, and could use some enlightenment. Temperature monitoring I do see the value in but I don't see the value of voltage or fan speed control. Is this just a suite for those who like to have all the data about their environment whether it's useful or not?

Regarding voltages, having access to that data I would think pretty much just says whether you are over-using or under-utilizing your PSU, in which case you need a new PSU. That doesn't strike me as a very valuable feature to have - a PSU that tells you that you that you bought the wrong one but only after you buy and install it. If anything they should include this for free, not charge a premium. Or is this more of a diagnostic tool than anything?

Regarding fan speeds, I really don't see why I should care. The PSU should regulate its own fans and shouldn't need to bother me, just like my CPU or GPU fans. I only ought to be notified if the fans are failing. Is there a common use case for this besides the desire for control?

Question - Corsair PSUs, LINK and iCUE Software | Tom's Hardware Forum
April 24, 2022 - Edit: looked around a bit and Thermaltake also offers that monitoring feature with several of their PSUs, Tt lineup: https://www.thermaltake.com/products/power-supply.html?cat=81 Though, i wouldn't buy Tt PSU. Tt isn't that good when it comes to PSUs. Though, some Tt units are good, but it would be best to avoid them completely. ... Hi. Just a quick question that I'm not seeing a clear answer for anywhere online. I have a Corsair HXI 750 (with the LINK port).
