Hashrate and algorithm

This ASIC miner delivers a nominal 220 Th/s on the SHA256 algorithm used by Bitcoin, Bitcoin Cash and Bitcoin SV. It targets operators who need predictable block-winning capability in a single air-cooled chassis.

Power and networking prerequisites

The unit requires a 220–277 V AC supply rated for at least 20 A and a 4000 W power budget at the wall. A wired RJ45 Ethernet 10/100 M connection and ambient temperatures between –20 °C and 45 °C are also mandatory for stable operation.

Efficiency upgrade from older SHA256 rigs

At 15 J/TH the S21 Pro+ reduces energy cost per terahash compared with earlier 30–40 J/TH models. The improvement justifies replacement when electricity price or hosting density makes the lower draw decisive for profitability.
