About the Bitmain Antminer S21 (195TH/s)

Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.

The Bitmain Antminer S21 (195 TH/s) is a high-performance SHA-256 ASIC that reads the Earth's electric pulse and converts it into deliberate computational force, delivering 195 terahashes per second at a consumption of 3,400 watts and an energy efficiency of approximately 17.44 joules per terahash; built with waterproof and dustproof components and a robust power supply design, it promises prolonged, uninterrupted operation for mining Bitcoin, Bitcoin Cash and Bitcoin SV, while advanced security protocols guard the integrity of the machine and the network work it joins. Compact and pragmatic in form-400 x 195 x 290 mm and 13.2 kg-it's engineered to fit into dense, professional rigs and large-scale deployments, designed to operate steadily across 0–45 °C and 10–90% relative humidity so environmental variation becomes an operational parameter rather than a threat. For operators focused on optimization, the S21’s blend of raw hashrate, measured efficiency and reliable hardware reduces the uncertainty around long-term yields, and paired with a crypto miner profit calculator you can model potential earnings and electricity expenses per day, month or year under different electricity rates and billing units to compare deployments, plan cooling and site power, and assess ROI with precision.

The Antminer S21 moves through server rooms like a quiet revenant of silicon and code, its 5 nm ASIC heart pounding out 195 terahashes per second while drawing 3,400 watts and achieving roughly 17.44 joules per terahash; built to work the SHA‑256 lanes that secure Bitcoin, Bitcoin Cash and Bitcoin SV, it blends raw hashing force with rugged build - waterproof and dustproof components, a reinforced power supply and a chassis compact enough at 400 x 195 x 290 mm and 13.2 kg to slip into dense professional rigs or sprawling farms - so the machine keeps grinding reliably across 0–45 °C and 10–90% relative humidity. Cooling is optimized with twin high‑speed fans and enlarged heat sinks that shepherd heat away even when ambient air climbs, while firmware-driven power management tweaks voltage and clock on the fly and an adaptive mining mode lets operators dial power use to match margins and site electrical limits. Security features are hardened to reduce the surface for remote intrusion, and the sturdier PSU architecture smooths out fluctuations that would otherwise dent sustained performance; together these elements lower downtime and support long, uninterrupted campaigns. For operators planning deployments, the S21’s combination of high hashrate, measured efficiency and compact reliability simplifies integration, cooling planning and power provisioning, and it plays well with profitability modeling tools so you can estimate daily, monthly and annual mining yields and electricity outlays under different scenarios without guessing.
