The Whatsminer M7AS is the pinnacle of liquid-cooling ASIC technology from MicroBT. Built for the SHA256 algorithm (BTC, BCH, BSV), this “S” tier upgrade pushes the boundaries of efficiency and raw power. It delivers an astonishing hashrate of 500T to 552T while maintaining a remarkable energy efficiency ratio of just 13.5 J/T.
Like its predecessor, the M7AS features a Dual-Mode operation (Normal at 7200W and High-Performance at 10kW) and is housed in a standard 2U rack-mount chassis (86 mm height). It can output water up to 70°C, making it a top-tier choice for high-density container deployments and industrial heat-reuse projects.
Astonishing 13.5 J/T Efficiency: The biggest leap in this model. By dropping the power ratio to 13.5 J/T, it dramatically lowers your operational electricity costs per terahash, ensuring maximum ROI potential.
Max Hashrate Output (Up to 552T): The M7AS provides a higher top-end hashrate compared to the standard M7A, giving your facility the brute computational force needed to stay highly competitive.
Dual-Mode Flexibility: Switch seamlessly between Normal Mode (7200W) for balanced power draw or High-Performance Mode (10kW) to unleash absolute maximum hashrate.
Ultra-High Density 2U Form Factor: Standing at just 86mm tall, this standard 2U server maximizes your rack space utilization, allowing you to stack significantly more hashrate per square meter.
Heat Reuse Ready: With an outlet temperature of up to 70°C, the generated thermal energy can be repurposed for industrial drying, agriculture, or district heating.

Q: What is the difference between the M7A and the M7AS?
A: The M7AS is an upgraded “S” model. It features a significantly better energy efficiency ratio (13.5 J/T vs 14.5 J/T) and a higher maximum hashrate (552T vs 526T). This makes the M7AS more profitable to operate over time.
Q: How do the Normal and High-Performance modes work?
A: In Normal Mode, the miner operates at roughly 7200W. In High-Performance Mode, it draws up to 10kW to push the hashrate to its maximum (up to 552T). Note: The required inlet water temperature is stricter in High-Performance Mode (25°C – 45°C).
Q: What are the power requirements?
A: It requires a 3-phase AC power supply ranging from 380V to 480V. It requires a custom power cable rated for at least 16 Amps.
Q: What is the required liquid flow rate?
A: The M7AS requires a rated flow of ≥ 10 L/min with a pressure not exceeding 400 Kpa.
Q: Why is the hashrate listed as a range (500T-552T)?
A: The exact hashrate depends on the specific batch and the operating mode (Normal vs. High-Performance). It carries a ± 10% fluctuation tolerance.
