Anatomy
Inside the M70S.
Dual fan airflow
Two fans drive air straight through the chassis. It fits our standard air cooled racks with no special infrastructure.
Hashboards
226 to 264 TH/s at about 13.5 joules per terahash, built for steady output over long runs.
Power supply
About 3,140 to 5,000 W depending on power mode, on AC 220 to 240 V. Industrial power, which is why most owners host it rather than run it at home.
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 M70Ss 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
Up to 264 TH/s at about 13.5 joules per terahash.
At about 13.5 J/TH, a machine near 3,500 W at $0.07 per kWh uses about $176 of electricity a month, roughly $2,117 over a year.
Returns depend on the hardware price, BTC price and how long you hold. It suits operators planning multi year holds, and for large fleets its per machine efficiency multiplies across every unit.
Who it suits
Made for these operators.
Efficiency focused, long holds
At 13.5 J/TH, the efficiency keeps paying off the longer the machine runs.
First time miners
Strong long term economics in a simple air cooled setup.
Fleet operators
Per machine efficiency that multiplies across many units.

Questions
About the M70S.
At about 13.5 J/TH the M70S is one of the most efficient air cooled miners available. Profitability depends on BTC price and network difficulty; the profitability calculator gives a live estimate.
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 M70S suits operators planning a long hold around 13.5 J/TH; the M70 suits operators who want top tier hashrate with the lowest upfront hardware cost in the series.
For most people, no. The Whatsminer M70S draws about 3,140 to 5,000 W depending on power mode, needs industrial AC 220 to 240 V power, and generates significant heat and noise, so most owners host it at a professional facility instead.
Yes, at $0.07 per kWh all in at our Southeast Texas facility, served by Entergy Texas, with no performance fees and 24/7 NOC monitoring.
The M73 delivers 470 to 526 TH/s at 14.5 J/TH in a single unit, drawing about 7,200 W, and is built for liquid cooled colocation. The M70S delivers 226 to 264 TH/s at 13.5 J/TH and is a strong fit for air cooled facilities.
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.
