Whatsminer M66S Hydro 300T questions
How much electricity does the Whatsminer M66S Hydro 300T use?
The Whatsminer M66S Hydro 300T draws 5,513 W at the wall. Running continuously that is about 132.3 kWh per day and 3,969 kWh per 30 days. Multiply by your electricity price to get the running cost, or use the calculator.
What is the hashrate and efficiency of the Whatsminer M66S Hydro 300T?
Rated hashrate is 300 TH/s at 18.4 J/TH (derived from rated power ÷ rated hashrate). Lower J/TH means less energy per unit of hashrate. See Understanding J/TH.
How is the Whatsminer M66S Hydro 300T cooled?
The Whatsminer M66S Hydro 300T 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.
Can I order the Whatsminer M66S Hydro 300T in bulk?
Yes. Orders are handled by quantity: small quantities through checkout when a price is published, and larger quantities by quotation with pricing, batch and logistics confirmed by sales. Request a wholesale quote.
