I heard they were going to go comercial hosting only ie box with blades 10 blades to a box each blade 10k or some such
in other words the RUMOR I HEARD is they are getting OUT of units for home use and kinda sorta hosting sold units to commercial firms and or rates 
*ie stuff that needs to be hosted* due to power and cooling requirements
(probably wrong but what I heard) 
bums me out the only trustworthy bunch out there in the world imho
wanted an SP20 but at 1200w with a Titan now and 100 amp service etc just can't make the $$$ fly with the numbers
of btc made
so it goes
dude why on earth do you think it uses 1200 watts.
if you just clock it to 1275 you will be at 700 watts. 
forgetting your power supply limits for 1 minute .
1200  watts high clock does   1650gh
700   watts low clock does     1275gh
470   watts  lower clock does 1025gh
400   watts  lowest clock does 900gh
the  record low  is here
