Actually, 4TH would be more like 1100W.
Still nice shaving of the power. More #'s for me to play with to see how much hash & 'spare' miners I can fit in my power budget.
edit: re: my free power (at work) advantage. While playing with numbers turns out I'm using 23kw there which at our rate works out to just s tad under $1,600/mo.

Anywho, after deducting that from what the entire farm brings in including what is at home, I'd still NET around $5k/mo. Think I might talk to my Partner about setting up an automatic Coinbase xfr to the company each mo to be nice, eh?
I can certainly afford the
BTC2.7-2.8 per month and it'd help a bit towards our current massive R&D expenses piling up for this year. To date that is somewhere close to $450k and climbing fast. That's not counting the usual price of a very nice Ultrafast laser from Trumpf
http://www.us.trumpf.com/en/products/laser-technology/products/solid-state-lasers/short-pulsed-lasers/trumicro-series-5000-femto-edition.html that is so far on a FREE 6/mo loan to us from them... OTH, I have nice shiny new toys to play, er, I mean do mid-Pico down to high Femto-sec time scales material interaction tests with. With a selectable choice of IR/Green/UV wavelengths no less.
