I may have found a solution, for my situation at least.
If I plug all 4 12V+ rails of the supernova into the Antminer, the psu tester WORKS. *been on for 2 hours now *crosses fingers**
Since I was never planning on using the supernova on more than one antminer, my issue is resolved (as long as it stays on).
However, if someone else wanted to use the supernova to power more than one antminer, I'm not sure how they would do it with this PSU.
Or if they wanted to power an S1, it would not work for that either.
found this late. the issue with that psu is multi 12 volt rails . it runs 1 s-3 only due to the multi- rails and you need to plug in the right amount of pcie cables.
