Bitmain Antminer S21 FAQs
The Bitmain Antminer S21 151T is an air-cooled ASIC miner for the SHA-256 algorithm. It is designed primarily for Bitcoin mining and can also process other compatible SHA-256 networks such as Bitcoin Cash and Bitcoin SV.
At an inlet temperature of 25°C, the S21 151T is rated for a typical hashrate of 151Th/s, power consumption of 2642W and efficiency of 17.5J/TH. BITMAIN notes that actual hashrate may vary by ±3%, while power and efficiency may vary by ±5%.
The miner measures 400 × 195 × 290mm without packaging and has a net weight of 15.4kg. Its packaged dimensions are 570 × 316 × 430mm with a gross weight of 17.2kg.
BITMAIN rates the S21 at up to 76dBA when its fans are running at maximum speed. It should be installed in a dedicated, well-ventilated mining area with appropriate noise control rather than a normal living space.
The S21 supports an operating temperature of 0–45°C and 10–90% non-condensing humidity. It requires a 220–277V single-phase AC supply at 50–60Hz, so the electrical circuit and ventilation should be prepared by qualified professionals.
The S21 uses a wired RJ45 Ethernet 10/100M connection. After connecting it to the local network, users can access the miner interface, configure a compatible SHA-256 mining pool and monitor its operating status.
