Ive emailed cointerra not to long ago to ask about the type/size of PSU's they were using for their 2th/s unit.  

Needless to say, they couldn't give me a solid answer just "we estimate we will be using dual 1100s", but wasnt certain.

I had also asked if the PSU's were server/redundant or standard ATX, if they met 80 gold or above standards.  In the end I got a screen shot of a 1100w psu that could have been grabbed from just about anywhere with none of that information needed.

I am not at all questioning these guy's abilities in what they can do, they are all obviously qualified ENGINEERS. The one thing I do see different with these gents is, none of them have run the entire ship.  Just departments of, which is fine. Though could very well lead to a late arrival. due to the desire of perfection/standard engineers flaw.  Normally that is a great thing, sadly its a slightly different nature with btc.

I hope they deliver, I really do. I like their ideas/ team.  



Hello,
Sorry for the delay in answer. We have indeed chosen our power supply (PSU) supplier and we are equipping our TerraMiner series with power supplies from Power One (http://www.power-one.com). Our decision was based on the need for exceptionally reliable power sources for durability and reliability.

Are you guys really going to delivery early January?  I really do want test out your system but the difficulty rate is rising too quickly.  It's hard to tell if any miner will even get ROI let alone a profit.  I started using cloud mining which has been fun so far.

So putting the two pieces of info together, this looks like the power supply we're talking about...

Its specs look excellent.  Its way better than 80-PLUS GOLD.   Better than 80-PLUS PLATINUM even.  it claims >94.5% efficient.
