I paid slightly less than 30K for my [upgrade] order of two BFL SC miniRigs, with an aggregate hash rate of 3 TH/s - so why would I want to pay 30K for a measly 400 GH/s?
An absurd proposition.
So is the minirig, at jally power draws, a minirig needs 9KW of power each. It's a portable fire starter and neighborhood light dimmer, and the power bill will each up a vast amount of profit.
the average household only can pull 3kw tops if you run everything you have all at once.
That's cute. The average doll house with an easybake oven?
Go check the power consumption of your oven and dryer and come back with your findings. I'd have had serious issues if I was capped at 3kW at my apartment.
