Notes
(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.

Comparison with Antminer S21 Hydro
The M66S++ Hydro and S21 Hydro are both advanced hydroponic systems designed for efficient plant growth, but they cater to different user needs. The M66S++ features a larger growing capacity and is equipped with a sophisticated nutrient delivery system, making it ideal for commercial growers or serious hobbyists looking to maximize yield. In contrast, the S21 Hydro is more compact and user-friendly, suitable for home growers or beginners who want an easy-to-manage system. While the M66S++ offers greater scalability and automation options, the S21 focuses on simplicity and accessibility, making both systems valuable depending on the grower’s experience level and space constraints.
