Thank you for all of the detailed feedback.  I heard back from my request to MyRig so I currently have a ticket open with them and am planning on shipping out the power supply next week.  I will keep you updated on my experience with them so the rest of the group can use it as a reference.

I also found that this model of power supply can be bought from Bitmain for $134 + a monster shipping charge.  They are currently out of stock, but I also saw that they were requesting a questionable amount of shipping information for the order.  I am digging into this a little more next week so I will keep you updated on that also.
