Frequently Asked Questions

Can it run on 120 V household outlets?

No. It requires a 200–240 V circuit. Running on 120 V can damage the unit.

How loud is it?

It’s industrially loud. Treat it like power tools running continuously — plan isolation and exhaust.

What impacts profitability?

Bitcoin price, network difficulty, pool luck, uptime, ambient temps, and your electricity rate.

Is firmware tuning recommended?

Advanced users may tune for efficiency, but stability and longevity should take priority.
