Dragonball Miner A40
Professional-Grade Miner
This miner draws 1,600W and produces 75 dB of noise — it is designed for dedicated mining environments, not living spaces. Professional-grade miners deliver the highest hashrate and revenue per unit but require proper infrastructure: a 240V circuit, adequate ventilation or exhaust ducting, and a space where noise is not a concern (garage, basement, warehouse, or outdoor enclosure).
For home miners looking for a quieter alternative, consider our Bitcoin Space Heater builds or explore open-source miners like the Bitaxe that are purpose-built for residential environments.
Heater-Class Miner
At 1,600W, this miner outputs approximately 5459 BTU/hr of heat — equivalent to a standard electric space heater. Every watt consumed by an ASIC miner is converted to heat with 100% efficiency, making it a space heater that also mines Bitcoin.
During heating season, miner heat can offset part of the heat a room would otherwise need from another electric heater. The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.
Profitability Calculator
| Period | Revenue | Electricity Cost | Profit |
|---|---|---|---|
| Daily | $0.09 | $2.69 | $-2.60 |
| Weekly | $0.63 | $18.82 | $-18.18 |
| Monthly | $2.72 | $80.64 | $-77.92 |
| Yearly | $33.05 | $981.12 | $-948.07 |
Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.

Home Mining Assessment
The Dragonball Miner A40 is a Blake3 cryptocurrency miner manufactured by Dragonball. It delivers a hashrate of 3.3 TH/s with a power consumption of 1600W, achieving an efficiency of 484.8 J/TH.
Operates at 75 dB noise level, weighs 14.5 kg, measures 360*185*290mm.
With a home mining score of 42/100, this miner is moderately suitable for residential use. It produces 5459 BTU/h of heat output, making it effective for supplemental space heating.
At 484.8 J/TH, the Dragonball Miner A40 sits in the legacy efficiency tier, so it is most economical run as a space heater or for hobby and learning setups rather than for pure profit.
Its waste heat (around 5459 BTU/h) can be ducted into a room, turning money you would otherwise spend on heating into hashrate.
