MicroBT Whatsminer · Air cooled
Whatsminer M70
Up to 242 TH/s. One of the top tier air cooled machines in the industry.
MicroBT's air cooled M70 ranks among the top tier miners in the industry, delivering 214 to 242 TH/s at about 14.5 J/TH. It carries the lowest upfront hardware cost in the series and suits operators who want strong hashrate with a lean capital outlay.
Price on request, because pricing changes with each batch. A person replies within one US business day. Buy it from us and we host it from a single machine at $0.07 per kWh, all in.
Anatomy
Inside the M70.
Dual fan airflow
Two fans drive air straight through the chassis. Air cooled means it drops into our standard air racks with no special infrastructure.
Hashboards
Where the hashing happens: 214 to 242 TH/s. The 242 TH/s figure is reached in overclock mode; normal operation sits toward the lower end.
Power supply
Rated from about 3,140 to 5,000 W depending on power mode, on AC 220 to 240 V. That is roughly what one or two electric clothes dryers draw, running nonstop.
Control board
A web interface for pool and wallet settings. For hosted units, we configure the pool and your payout address for you.
Run the numbers
What a fleet of M70s costs to run.
Electricity only, at our all in rate of $0.07 per kWh. Revenue depends on BTC price and network difficulty, which the profitability calculator models live.
Based on a typical 3,500 W draw, running 24 hours a day for 30 days. Real draw ranges from about 3,140 to 5,000 W depending on power mode.
In practice
The M70 delivers top tier hashrate with a lean upfront outlay.
At about 14.5 J/TH, a machine near 3,500 W at $0.07 per kWh uses about $176 of electricity a month, running around the clock.
It suits operators who want hardware hashing quickly, whether for a shorter hold or to spread capital across a larger fleet. Over a multi year hold, its 214 to 242 TH/s keeps running at the same flat all in rate.

Questions
About the M70.
Profitability depends on BTC price, network difficulty and your electricity cost. At $0.07 per kWh, the M70's 214 to 242 TH/s at about 14.5 J/TH is competitive for hosted operations. The profitability calculator gives an estimate from current network conditions.
For most people, no. The Whatsminer M70 draws about 3,140 to 5,000 W depending on power mode, roughly one or two electric clothes dryers running nonstop. It needs an AC 220 to 240 V connection and produces significant heat and noise. Most operators host it at a professional facility instead.
The M70 delivers 214 to 242 TH/s at about 14.5 J/TH; the M70S delivers 226 to 264 TH/s at about 13.5 J/TH. Both draw about 3,140 to 5,000 W depending on power mode. The M70 suits operators who want top tier hashrate with the lowest upfront hardware cost in the series; the M70S suits operators planning a long hold around 13.5 J/TH.
Yes. We host the M70 in Southeast Texas, served by Entergy Texas, at $0.07 per kWh all in, with no performance fees and 24/7 NOC monitoring.
Connect it to an AC 220 to 240 V supply, join a mining pool, and enter your pool credentials and Bitcoin wallet address in the web interface. For hosted units, we handle the whole setup.
Every miner we sell is factory new and carries MicroBT's standard one year manufacturer warranty, issued and honored by MicroBT; Fathom Labs is not the warrantor. The only exception is a used unit, which we always label as used and which does not carry the new unit warranty. For coverage details, exclusions and the claim process, ask us at the time of purchase or contact MicroBT directly.
Real world hashrate varies about 3% and power draw about 5% from rated figures. Verify current firmware specifications with MicroBT. Price on request: availability and pricing change with each batch.
