Hello,
Software readings for the PSU rails aren't the most accurate way of measuring voltage. A faulty PSU can be difficult to diagnose without the proper equipment (PSU testers or multi-metres do not have the necessary frequency). It's also important not to run multiple polling tools on the system as this can produce an erroneous voltage reading.
However, given the behaviour you're seeing it would indicate there is enough sag to induce the power LED to light up. This is only going to get worse so I would recommend looking to replace the power supply at some stage.

So either I have a super efficient PSU or I'm drawing too much voltage, either way I am still getting the middle red indicator led on my white rog strix 3090 (full retail price version)

I meant to add a gpuz shot with that, but it only let me add one at a time.

Hi @Silent_Scone . Thanks for your interest.
As things stand now, the issue is gone and impossible to reproduce again when I make sure to align all three card-side power connectors. I tried shifting the power connectors PSU-side, power limits, and the previously used cable. It was some work on my end, but everything else was eliminated, save for how the cables are plugged into the graphics card. I hope this message reaches out to the folks who also see this. If something, they can double-check how the cables are plugged and never forget to power off and take everything off power before doing anything.
I will take it for what it is, and look further to how I can reduce the amount of vibrations to which the graphics card is exposed in my setup — it's literally standing in an air tunnel, which is on the same desk where I game, so there you go. Also, since the cables do get wiggly over time, perhaps a new set can be obtained at some point.
In conclusion, My PSU is solid, despite the incident. I can trust its self-test going forward.
Be so as it may that GPU-Z has its limitations, the two power connectors on the graphics card experienced the issue separately. In both cases, there was a correlation to GPU-Z-measured voltage on that plug. I.e., putting a load on the graphics card while any of the connectors was under a certain threshold was also accompanied by the red blinking on that connector.
