I've been mining for years. Thought is was about time I posted a little something.
Here's my current rig.
6 - S7's overclocked total avg. 30.40 Ths
Total system pulls 62.3 amps
Rig dumps exhaust into my forced air return duct.
Currently in my area I have my power flat rate power for the next 1 1/2 years.
Total electric for the entire house is $450 a month.
Because of the flat rate, I can run the miners and the A/C at the same time and during the winter they keep my house around 70 deg.
