Interesting results!

 

I’ve not needed to have any solutions for my three 5090s using a Seasonic 1600W Titanium ATX 3.1 PSU … on my workstation PC, I’m running two of my 5090s off a single Seasonic PSU as they provide two 12VHPWR cables and ports.  I do a lot of AI processing/rendering so both GPUs are working heavy loads.  No issues after 1 year of regular heavy usage.

I had purchased one of Roman’s 12VHPWR monitoring connectors but after a month or so, removed it from my Flight Sim PC.
