Payback period
—
No payback while the machine runs at a loss
Revenue assumes a 1% pool fee at the current KAS 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 Payback needs a hardware cost, which we do not publish because we have no verified retailer feed — add your own purchase price in the calculator.

Data provenance
Manufacturer datasheet as published by retailers; hashrate and power corroborated across multiple sources. Last verified 2026-08-03.
Note: Published sound ratings sit between 75 dB and 76 dB depending on the seller, so we have not given a single figure.
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.
