Equihash · air-cooled
Equihash hardware is a thin market with few buyers, so resale is harder than for SHA-256. Treat the payback figure as less reliable than the headline suggests.

No payback while the machine runs at a loss
Revenue assumes a 1% pool fee at the current ZEC price and network difficulty, with the machine running continuously. Payback needs a hardware cost, which we do not publish because we have no verified retailer feed — add your own purchase price in the calculator. Your rate is saved in this browser and applies across the site.

Data provenance
Manufacturer datasheet as published by retailers; hashrate and power corroborated across multiple sources. Last verified 2026-08-03.
Note: We previously published 2,500 W for this model, which was wrong — the datasheet figure is 2,780 W. The published efficiency of 3.31 J/Ksol confirms it (2,780 ÷ 840). The correction lowers its break-even electricity price by roughly a tenth. Sound ratings vary between 72 dB and 75 dB, so none is listed.
Any field not listed above is one we could not verify for this machine. We would rather leave a row out than publish a figure you cannot check. Where published sources disagree, we say so instead of picking one. How we verify specifications.

The seven-day average passed 1,000 EH/s for the first time since March 3, and chain data shows difficulty already 5.92% higher since October 16, with another increase due around October 29.
Release 34-106659 approves Cboe binary contracts on indicators that 23 listed companies report, and Marathon Digital Holdings' list covers BTC produced, blocks won, total holdings and energized hashrate. Settlement reads the figure in the company's SEC filing rather than its earnings press release, and nothing can list until Cboe Clear U.S. is registered as a clearing agency.
The miner agreed to buy an 80-megawatt Ethiopian site almost two years ago, and on September 28 the facility's power supplier gave its operator ten days to pay a disputed bill or lose collateralized equipment. BitFuFu says it is weighing termination and arbitration against the sellers.
