Well, 6 months later I finally had the time and presence of mind to try to replace the power supply on the eGPU I got for my wife...and it still doesn't work, I'm disappointed to announce. I am going to presume this is an issue with the system board on the enclosure itself, as the power supply is new (though I haven't done the paper clip short test...couldn't find a paper clip and didn't want to go to the effort of disassembly).
Also want to test to be sure the GPU itself is good.
