Whatsminer M79S Specifications

Specification note: Current seller and mining-database listings consistently describe the Whatsminer M79S as a 1.35PH/s, 20kW hydro miner. However, a dedicated official MicroBT product sheet confirming every measurement, connector, coolant value, and tolerance was not publicly available when this page was prepared.

Buyers must verify the factory label, operating mode, firmware-reported hashrate, wall-power requirement, dimensions, coolant type, connector system, flow rate, pressure limits, and warranty before purchase.

Whatsminer M79S Mining Overview

Whatsminer M79S Bitcoin Mining Performance

The Whatsminer M79S delivers up to 1.35PH/s, or 1,350TH/s, according to current seller listings. This extremely high output enables one machine to contribute more than one petahash per second to a compatible SHA-256 mining pool.

Actual accepted hashrate may vary because of factory binning, firmware mode, coolant temperature, flow rate, system pressure, power quality, network uptime, pool latency, chip condition, and environmental conditions.

Operators should compare the local dashboard with pool-side accepted hashrate over several hours or days. Short-term interface readings may not represent sustained accepted output.

Important operating indicators include:

• Real-time and average hashrate
• Accepted and rejected shares
• Hashboard status
• ASIC chip errors
• Coolant inlet temperature
• Coolant outlet temperature
• Coolant flow rate
• Loop pressure
• Pump status
• Measured wall power
• Pool latency
• Network uptime

A sustained decline in Whatsminer M79S performance may indicate insufficient coolant flow, excessive inlet temperature, trapped air, incorrect pressure, unstable electricity, pool interruption, firmware problems, or a hashboard fault.

Whatsminer M79S 14.81J/TH Efficiency

Dividing the seller-listed 20,000W power consumption by 1,350TH/s gives the Whatsminer M79S a calculated efficiency of approximately 14.81J/TH.

At a continuous 20kW load, estimated electricity consumption is:

• 480kWh per day
• 3,360kWh per week
• 14,400kWh per 30-day month
• 175,200kWh per year

Estimated monthly miner-only electricity costs are:

• At $0.03/kWh: approximately $432
• At $0.04/kWh: approximately $576
• At $0.05/kWh: approximately $720
• At $0.06/kWh: approximately $864
• At $0.08/kWh: approximately $1,152
• At $0.10/kWh: approximately $1,440
• At $0.15/kWh: approximately $2,160

These figures cover only nominal miner consumption. Pumps, heat exchangers, dry coolers, cooling towers, container controls, transformers, routers, lighting, and electrical-distribution losses increase the facility’s total load.

Bitcoin mining profitability is not guaranteed. Bitcoin price, network difficulty, block rewards, transaction fees, mining-pool fees, electricity rates, cooling overhead, hardware price, downtime, repair costs, and operating mode all affect returns.

Whatsminer M79S Hydro-Cooling Requirements

The Whatsminer M79S requires a professionally engineered closed-loop liquid-cooling system. Coolant absorbs heat inside the miner and carries it to an external heat exchanger or cooling system.

A 20kW miner produces approximately 20kW of continuous heat. Hydro cooling transfers this heat more efficiently than high-speed airflow, but it does not eliminate the thermal load.

Typical Hydro System Components

• MicroBT-compatible coolant
• Circulation pumps
• Supply and return manifolds
• Compatible hoses and quick connectors
• Flow meters
• Pressure sensors
• Coolant-temperature sensors
• Expansion tank
• Air-separation and bleeding points
• Coolant filtration
• Heat exchanger
• Dry cooler or cooling tower
• Leak detection
• Automatic emergency shutdown

Hydro-Cooling Safety

• Use only coolant approved for the delivered mining system.
• Flush all new pipes and manifolds before connection.
• Remove trapped air before applying mining load.
• Maintain the manufacturer-required flow and pressure.
• Monitor inlet and outlet temperatures continuously.
• Inspect fittings, hoses, seals, and manifolds regularly.
• Protect all electrical connections from leaks.
• Prevent condensation around boards and connectors.
• Shut down the miner immediately if circulation stops.
• Do not substitute untreated tap water for approved coolant.

The final cooling-system design must use the official specifications supplied with the Whatsminer M79S. Do not design a facility from seller estimates alone.

Mineable Coins with Whatsminer M79S

Other technically compatible networks may include Fractal Bitcoin, eCash, Bitcoin SV, Peercoin, and other SHA-256 cryptocurrencies where appropriate firmware, pools, wallets, and exchange liquidity are available.

Before changing networks, compare mining difficulty, block rewards, expected revenue, pool support, payout thresholds, wallet compatibility, and market liquidity.

For general information about Bitcoin and proof-of-work mining, review the official Bitcoin educational resources.

Whatsminer M79S Mining-Pool Setup

The Whatsminer M79S will normally connect to a professional SHA-256 mining pool. Pool mining combines hashrate from many machines and distributes rewards according to accepted shares and the pool’s payout method.

Before choosing a mining pool, compare:

• Pool fees
• Payout method
• Minimum payout threshold
• Server locations
• Historical uptime
• Security controls
• Monitoring tools
• Failover-server support
• Accounting and API features

Pool configuration normally requires a Stratum server URL, worker name, password, and payout address. Secondary and tertiary pool servers should be configured where supported.

The Ethernet interface of the Whatsminer M79S should connect to a secure network with firewall protection, monitoring, restricted administrative access, and backup connectivity where practical.

Whatsminer M79S Electrical Requirements

The Whatsminer M79S is listed for 380–480V AC three-phase power. It cannot be operated from a standard household single-phase outlet.

At a nominal 20,000W load, approximate balanced three-phase line current is:

• Approximately 30.39A per phase at 380V, assuming a power factor near 1
• Approximately 27.83A per phase at 415V, assuming a power factor near 1
• Approximately 24.06A per phase at 480V, assuming a power factor near 1

Actual current may be higher because of power factor, startup behaviour, operating tolerance, cable losses, firmware mode, and continuous-load derating requirements.

The original 16A cable specification should not be used for this 20kW configuration without official factory confirmation. A 16A cable would generally be insufficient at the listed voltages if the machine truly draws 20kW.

Electrical preparation may require:

• A grounded 380–480V three-phase supply
• A correctly rated industrial breaker or fused disconnect
• Conductors sized for continuous duty
• A manufacturer-approved connector and cable assembly
• Overcurrent and surge protection
• Phase monitoring
• Emergency shutdown controls
• Dry and protected electrical terminations
• Power-quality monitoring
• Compliance with local electrical codes

A licensed industrial electrician must design and approve the electrical system before the Whatsminer M79S is energized.
