Product Overview

The Whatsminer M50 124T is the top-tier variant of MicroBT’s M50 series, offering the highest hashrate in the M50 family at 124 terahashes per second. As a Bitcoin (BTC) SHA-256 ASIC miner, it delivers the best performance-per-unit within the M50 lineup while maintaining the same physical chassis and power infrastructure requirements as the 118T and 120T siblings.

The M50 series is built on MicroBT’s advanced chip node technology, representing a clear generational improvement over the M30S era in terms of energy efficiency. The M50 124T is particularly suited to operators who want to extract maximum hashrate from each rack slot, as the higher hashrate-per-unit reduces the number of machines needed to achieve a given total output compared to lower-tier variants.

This is a proven, widely deployed model in Bitcoin mining farms globally. It operates at approximately 26.6 J/TH efficiency, making it one of the more competitive air-cooled miners available in the current generation of hardware without requiring exotic cooling infrastructure.

Key Features

• 124 TH/s hashrate: The highest output in the M50 series, maximising Bitcoin mining contribution per deployed unit and per unit of rack space occupied.
• ~26.6 J/TH efficiency: At approximately 3300W power draw, the M50 124T achieves roughly 26.6 J/TH — a significant improvement over older M30S hardware and competitive with contemporaneous models from Bitmain.
• Air-cooled, dual fan design: Requires no specialised cooling loop or immersion tank. Standard rack deployment in a ventilated mining room is sufficient, keeping infrastructure costs lower than hydro or immersion alternatives.
• SHA-256d algorithm: Mines Bitcoin (BTC) natively, with compatibility for other SHA-256d networks including Bitcoin Cash (BCH) and Bitcoin SV (BSV).
• Same infrastructure as M50 siblings: Identical form factor, power envelope, and connectivity as the M50 118T and 120T — operators can expand or mix variants without any infrastructure changes.
• Wired Ethernet connectivity: Single RJ-45 port for reliable, low-latency pool connection. Web interface accessible via local IP for configuration and monitoring.
• MicroBT reliability track record: MicroBT is one of the two dominant ASIC manufacturers for Bitcoin mining. The M50 platform has extensive field deployment data and community firmware support.

Power & Installation Notes

South Africa’s 230V/50Hz grid supply is fully compatible with the Whatsminer M50 124T’s 200–240V AC input. No voltage conversion is needed.

The M50 124T draws approximately 3300W continuously — this is the equivalent of running more than two electric geysers simultaneously. A dedicated 20A–32A circuit, installed and certified by a registered electrician, is essential. Standard 16A household circuits are not sufficient for continuous high-wattage operation. Do not plug this miner into a shared domestic outlet.

Load shedding is a material concern for South African mining operations. At 3.3 kW, no standard residential UPS or home battery inverter system can support extended operation during outages — a 10kWh home battery would be depleted in approximately 3 hours at full load. Operators targeting continuous uptime should have a generator or commercial-grade standby power system in place.

Thermal management is critical: the dual fans exhaust a significant heat load. Installation spaces must have active air extraction, and the ambient temperature should remain below 40°C. Mining rooms in South African summer conditions can exceed this without dedicated cooling or ventilation, which must be accounted for in the facility design.

Electricity Cost Context — South Africa

Running the Whatsminer M50 124T at 3300W for 24 hours a day consumes approximately 79.2 kWh per day, or roughly 2 376 kWh per month. Using Eskom’s reference residential tariff of approximately R2.80/kWh (note: actual rates vary by municipality), the estimated monthly electricity cost is approximately R6 653 per month.

Calculation: (3300 ÷ 1000) × 24 × 30 × R2.80 = ~R6 653/month.

This operating cost makes the M50 124T impractical for home mining on standard residential tariffs. It is best suited to operations with commercial power agreements, industrial tariffs, or access to cheap renewable energy. This is an electricity cost estimate only and is not a profitability forecast.

Ideal Use Cases

• Commercial and industrial mining operations: Operators managing 10–100+ units in a purpose-built or converted facility with dedicated power supply infrastructure.
• Maximising output per rack slot: When space is at a premium, the 124T delivers 5% more hashrate per occupied rack unit compared to the 118T, allowing smaller farms to achieve higher total output.
• Bitcoin pool mining participants: The M50 124T is compatible with all major SHA-256 pools — Foundry, AntPool, F2Pool, ViaBTC, and Braiins. Reliable for stable, consistent pool-based income.
• Hardware refresh for M30S or older operators: A direct replacement for M30S++ or M30S+ units, offering approximately 25–30% better efficiency in the same or similar rack space.
• Building a flagship M50 fleet: Operators who want the highest-performing M50-series model as their primary unit, with the option to supplement with lower-binned 118T or 120T units as budget allows.

Frequently Asked Questions

Does the Whatsminer M50 124T work on South African power?
Yes. SA’s 230V/50Hz supply falls within the M50 124T’s rated input range. A dedicated 20A–32A circuit from a qualified electrician is required for safe continuous operation.

How does the M50 124T compare to Bitmain’s S19k Pro?
The M50 124T and Bitmain Antminer S19k Pro are broadly competitive in the same performance class. The S19k Pro 120T offers 120 TH/s at approximately 23 J/TH — slightly more efficient — while the M50 124T delivers 124 TH/s. Choice often depends on availability, price, and operator preference for either MicroBT or Bitmain ecosystem tooling.

What mining pools are compatible with the Whatsminer M50 124T?
All standard Stratum-protocol Bitcoin pools work with the M50 124T, including Foundry USA Pool, AntPool, F2Pool, ViaBTC, and Braiins Pool. Pool configuration is done via the miner’s web interface using your local network IP address.

How loud is the M50 124T?
At approximately 75 dB(A), it is as loud as a petrol lawnmower running continuously. It is not suitable for home interiors and should be operated in a dedicated, sound-managed space.

What is the difference between the M50 118T, 120T, and 124T?
All three share the same chassis and efficiency class. They differ only in hashrate binning from the chip manufacturing process. See also: Whatsminer M50 118T and Whatsminer M50 120T.
