It will require a 3425W power supply, therefore running at an efficiency of 0.36 Joules/MH and will cost a reported 100,000 Yen or ~$15,000 but comes with a 13% discount for overseas purchases. According to Coinwarz at an electricity unit cost of $0.1 per KWH the profitability on the L7 is around $100/day based on the current market value of Litecoin and Dogecoin (which is merge mined with Litecoin).
