Bitmain Antminer S21+ Hydro 395Th/s

Bitmain Antminer S21+ Hydro 395Th/s is a high-performance water-cooled solution that debuted in February 2025. It runs on the SHA-256 algorithm and develops up to 395 TH/s at an energy consumption of 6000W. The energy efficiency level is 17 J/TH, making it one of the best in its class. This miner is great for mining SHA-256-based cryptocurrencies such as Bitcoin (BTC), Bitcoin Cash (BCH), Peercoin (PPC) and others. There are no fans in the design – they are replaced by a closed-loop liquid cooling system, thanks to which the device operates quietly (up to 50 dB) and can be used not only in mining, but also in heat recirculation systems. Three-phase power supply with voltage from 380 to 415 V is required for correct operation. The device is equipped with a built-in power supply unit and is connected to the network via a standard Ethernet interface. The miner weighs only 15 kg and is compact in size, which makes it easy to install in racks or cabinets, as well as subsequent maintenance. The equipment is manufactured in the People’s Republic of China, delivered new and officially provided with a 6-month warranty from Bitmain. Additionally, ASICFOX provides the same warranty for six months, taking into account possible delays in returning to the factory – all typical warranty cases are covered. The Antminer S21+ Hydro 395Th/s is the ideal choice for users who want to maximize computing power with low power consumption. With its stability, efficiency and advanced cooling, the device is suitable for both private enthusiasts and large-scale mining operations.
