Mining Calculator Bitmain Antminer S21+ Hyd 319Th

The Bitmain Antminer S21+ Hyd (319Th) model is an ASIC miner for the SHA-256 algorithm, part of the flagship S21 series. Announced for February 2025, the device is designed for industrial mining and targets operators requiring maximum energy efficiency with liquid cooling. Its form factor is a compact standalone unit, not a rack-mounted solution.

The key metrics are a hashrate of 319 TH/s with a power consumption of 4785 W. This results in an energy efficiency of 15 Joules per Terahash (J/TH). This parameter is one of the most competitive on the market, placing the device among the most technologically advanced models. High energy efficiency is the primary factor ensuring the miner’s long-term profitability, especially in conditions of high network difficulty.

The hydro-cooling system (“Hyd”) is a fundamental feature, evidenced by its low noise level of 50 dB. This solution ensures stable heat dissipation and allows the miner to be used in denser configurations. However, operation requires external infrastructure: a closed cooling loop with radiators (dry coolers), a pump, and coolant. The device is not autonomous and cannot operate without connection to this system.

Ultimately, the Antminer S21+ Hyd is a highly specialized tool for professional mining operations. Its economic viability is determined by three factors: the final market price, the cost of electricity, and the capital expenditure for deploying the necessary cooling system. The indicated daily revenue is a calculated and volatile figure.
