MicroBT WhatsMiner M70S | 258 TH/s Bitcoin Miner | 13.5 J/TH | Balanced Air-Cooled ASIC
The MicroBT WhatsMiner M70S is a standard-efficiency, air-cooled ASIC miner from MicroBT’s new M70 series, designed to offer a balanced and cost-effective entry into competitive Bitcoin mining. Delivering up to 258 TH/s with a power consumption of 3480W, it achieves a solid 13.5 J/TH efficiency. Leveraging 5nm chip technology and a dual-fan cooling system, the M70S is engineered for reliable 24/7 operation, making it a practical choice for both mid-sized farms and serious home miners with proper infrastructure.
Performance & Positioning
-
Balanced Efficiency for Current Markets: With a 13.5 J/TH efficiency, the WhatsMiner M70S is positioned as a practical workhorse, offering a compelling balance between upfront cost and ongoing electricity expense, crucial during periods of compressed mining profitability.
-
Advanced 5nm Chip Foundation: Utilizes next-generation 5nm ASIC technology, providing improved performance-per-watt over previous chip generations and contributing to its overall efficiency.
-
Proven Air-Cooling Simplicity: The reliable dual-fan design offers a straightforward thermal solution, avoiding the complexity and added cost of liquid cooling systems, which makes it easier to deploy and maintain.
-
Accessible Performance Tier: The 258 TH/s output provides a significant hashrate boost for operations scaling up, serving as an effective upgrade path from older 100-150 TH/s miners without requiring a leap to extreme power or cooling infrastructure.
Critical Requirements & Considerations
-
Substantial Power & Circuit Needed: The 3480W power draw requires a dedicated and stable 220V/20-25A circuit. A standard 110V household outlet is completely insufficient. Home users must verify their electrical panel’s capacity.
-
Noise and Heat Are Significant: The 75 dB operational noise is substantial (comparable to a vacuum cleaner) and it generates considerable heat. It is not suitable for living areas and requires a dedicated, well-ventilated space such as a garage, shed, or insulated mining room.
-
Environment is Key: For optimal performance and to prevent overheating, it should operate in a clean, dust-managed environment with good ambient airflow.
-
Pre-Release Product: Specifications for this December 2025 release are preliminary. Final performance metrics, pricing, and availability should be confirmed with official MicroBT distributors closer to launch.
