Lets refresh readers memory:
Yes, I do believe the unit will produce up to 1.2THs, running around 600Watts.
...
Worst case scenario, as per specs... I can see the "boards" consuming 600Watts, with the rest consuming about 20Watts for the controller and fans, prior to the PSU. With a horrid 80% efficiency, that would put it at a 750Watts at the wall, roughly.
And.. what chip-count was that quoted with? The "..." missing context is the important other half of that whole conversation... I believe the chip count was up near the 60's for that to be delivered, now it is down to the 50's, with the updated specs, which is still "near 600w" possibility. (I still agree that 900w is more realistic, for 120v systems.)
However, it is the "new miners" being quoted at those specs... I still "psychologically", hold some claim to the unit specs I purchased, at the price and time I made the purchase. (Which was around 600w.

) But, given the nature of the order and business and market, I would accept the current adjusted realistic 900W +/-10% as "acceptable".
When my order gets here, that will be taken into consideration too. Just like BFL had to double-up on chips, to get the specs within estimated projections. (Though BFL fell short on power by 5x loss. AMT would actually gain power by adding chips, running below nominal voltages. BFL was just a power-hungry chip with little room for adjustment.)
I would hope that they attempt to adjust for that claim. I'll dig-up that dead post when the time comes.
