Whatsminer M7A 526T 14.5 J/T 470 T – 526 T Hydro Miner

Description

The Whatsminer M7A is a state-of-the-art, industrial-grade liquid-cooling ASIC miner engineered by MicroBT. Built for the SHA256 algorithm (supporting BTC, BCH, BSV), it delivers a massive hashrate of 470T to 526T with an exceptional energy efficiency ratio of 14.5 J/T.

Designed for maximum flexibility and high-density scaling, the M7A features a Dual-Mode operation: a Standard Mode running at 7200W and a High-Performance Mode running at 10kW. Housed in a standard 2U rack-mount chassis (86 mm height) and capable of outputting water up to 70°C, it is the ultimate choice for mega-farms looking to maximize space, reduce electricity costs, and explore heat reuse applications.

Why Choose the Whatsminer M7A?

• Industry-Leading 14.5 J/T Efficiency: A massive upgrade in power efficiency. The M7A drastically reduces your operational electricity costs per terahash, ensuring maximum profitability even in tough market conditions.

• Dual-Mode Operation (双模式运行): Flexibility at its core. Choose Normal Mode (7200W ± 10%) for a balanced power draw, or switch to High-Performance Mode (10kW ± 10%) to extract the absolute maximum hashrate out of the machine.

• Ultra-High Density 2U Form Factor: Standing at just 86mm tall, this standard 2U server design maximizes your rack space utilization, allowing you to stack significantly more hashrate per square meter.

• Heat Reuse Capability: With an outlet temperature reaching up to 70°C, the generated heat can be effectively utilized for industrial drying, greenhouse heating, or district heating systems.

• Robust Power & Cooling Design: Supports wide 3-phase voltage (AC 380V – 480V) and requires a standard liquid flow of ≥ 10 L/min, ensuring stable operation in professional hydro containers.

Frequently Asked Questions (FAQ)

Q: What is the difference between the M7A and the M65S?
A: The M7A offers superior energy efficiency (14.5 J/T vs 18.5 J/T) and a higher maximum hashrate (526T vs 400T). However, it requires a higher liquid flow rate (≥ 10 L/min vs ≥ 5 L/min) and its max outlet temperature is 70°C instead of 80°C.

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 capability. Note that 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 coolant should be used?
A: You must use a special coolant mixture: Pure water (or distilled water) combined with a special corrosion inhibitor and antifreeze. The liquid pH must be strictly maintained between 7 and 8.7.

Q: Why is the hashrate listed as a range (470T-526T)?
A: The exact hashrate depends on the specific batch, the quality of the silicon, and the operating mode (Normal vs. High-Performance). It has a ± 10% fluctuation tolerance.
