The Whatsminer M66 Hydro 280T draws 5,572 W at the wall. Running continuously that is about 133.7 kWh per day and 4,012 kWh per 30 days. Multiply by your electricity price to get the running cost, or use the calculator.
Rated hashrate is 280 TH/s at 19.9 J/TH (derived from rated power ÷ rated hashrate). Lower J/TH means less energy per unit of hashrate. See Understanding J/TH.
The Whatsminer M66 Hydro 280T is hydro-cooled: heat is removed by liquid circulating through cold plates, so it needs an external cooling loop (pump, heat exchanger or dry cooler) and cannot run on fans alone. Compare options in Air vs hydro Bitcoin miners.
