I really dont know how to state this to be perfectly honest so just follow on me if you can, but what does it mean when the site says "its power efficiency is 0.77J/GH at the wall". I am a bit lost and I just need someone to buzz my brain and it should pop up clear as day, but I am trying to work out what information I would put into a calculator like this regarding power usage or just over all everything if your kind enough to lead the right way through some screen shots

Any of your help or other suggestions regarding mining I would greatly appreciate.
Thanks, Paddy
The direct store (link) I am buying from, sadly I live in Australia and we are very much behind when it comes to technology now so I must pay a lot more than most of you lucky guys
