Just received my New R-Box and very puzzling thing happens when I try to power it up, I have tried 3 different PSUs and when I turn them on I get nothing from the R-box and in all 3 cases the PSU dies instantly when I plug the Miner in hot.  I suspect there is something wired wrong in the New R-Box but before i go rooting around in it I thought I would see if anyone else has had this issue.  Thanks in advance.
