I assumed server PSU, they didn't say that, but since they specifically said HP, I assumed they meant some sort of HP Server PSU and not a standard ATX.  So that may be my fault there.  It may very well be an ATX adapter.  I'll ask for clarification.

I've suggested various things that most people voice here.  Refunds, Compensation, Alternatives, etc.  If I get any news I'll let you know. 

This actually makes a good bit of sense.  Minersource sells HP, Dell, Delta etc Server PSUs.  Their HP and Delta models are both 1000W+ PSUs (don't remember exactly what wattages).  The issue here is that ATX PSUs capable of supplying the ~1200 watts (on the 12V rail alone, so think 1500W ATX PSU) each X3 unit requires could cost upwards of 300 USD.  The ~1200W HP server PSU on the other hand is sub-100 USD.  And can be sourced in bulk easier than consumer ATX PSUs.  That's my guess anyway.  The only issue I see here is the fact that high wattage server PSUs typically require 208-240V to run at full capacity.  A lot of US customers (like myself) only have easy access to 110-120V circuits.
