Maxi 39T questions
How much electricity does the Maxi 39T use?
The Maxi 39T draws 1,500 W at the wall. Running continuously that is about 36 kWh per day and 1,080 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 Maxi 39T?
Rated hashrate is 39 TH/s at 38.5 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 Maxi 39T cooled?
The Maxi 39T is air-cooled with built-in fans. It needs a steady supply of cool intake air and a path to exhaust hot air. Compare options in Air vs hydro Bitcoin miners.
Can I order the Maxi 39T 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.
