About the Bitmain Antminer S21 (188TH/s)
Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.
The Bitmain Antminer S21 sits like a precise instrument scraped raw from a neon gutter-188 terahashes per second of SHA-256 power, a humming cathedral of silicon that chews cryptographic puzzles for Bitcoin, Bitcoin Cash, Bitcoin SV and their algorithmic kin with a relentless appetite; it draws a steady 3,290 watts and balances brute force with a surgical efficiency of about 17.5 joules per terahash, four fans bellowing through a 75-decibel chorus as a hardened cooling array shepherds heat away to keep hashboards honest and component life stretched thin but long, its 195 x 290 x 400 mm chassis and 14.4-kilogram frame compact enough to slip into dense racks yet built like industrial jewelry for the scaled farm or the stubborn solo operator; firmware update channels lock down integrity against tamper and ghosted identities while refined electronics and a robust housing let it shoulder continuous loads without theatrics, the whole business of it gleaming dangerous and useful, a tool for operators who trade sustained throughput and measured uptime rather than publicity stunts, complete with practical modeling-daily, monthly and yearly yield estimators that fold in electricity profiles and rate structures so you can plot optimization, manage thermal and financial risk, and trace long-term ROI in a market where machines, power and people shift like shadows, a beautiful, filthy, lethal engine that secures chains and counts the transactions that keep the ledger alive.

The Antminer S21 arrives like an obsidian talisman buried in the hum of a data hall, an ASIC carved to the geometry of proof itself whose heart beats at 188 terahashes per second across the SHA-256 rites that bind Bitcoin, Bitcoin Cash and Bitcoin SV to consensus; it drinks 3,290 watts of mains current as if fueling an electric hearth, trading power for work at roughly 17.5 joules per terahash while four fans expel heat in a steady 75-decibel wind that reads like a low liturgy to anyone standing close, its compact 195 x 290 x 400 mm frame and 14.4-kilogram mass making it both portable grimoire and industrial artifact fit for cramped racks or sprawling farms. Beneath the brooding silhouette lies engineering that thinks in longevity: a disciplined cooling architecture and directed airflow channels to keep hashboards cool under sustained load, power electronics refined to minimize losses between wall and chip, and firmware that acts more like a warded conductor-secure update channels, integrity checks and adaptive frequency behaviors that modulate performance as ambient conditions shift so uptime is less a hope and more a managed outcome. For the operator this translates into practical certainties: predictable hashrate and thermal profiles that simplify rack layout and ventilation planning, clear electrical provisioning needs that demand dedicated circuits and attention to circuit breakers and PDU choices, and maintenance rhythms informed by durable construction and accessible component placement that reduce downtime and spare-part surprises. Noise, size and weight make the S21 a decision as much about site selection as about raw hashing-consider sound isolation, intake air quality and exhaust routing when stacking units densely-and monitor power draw and temperatures continually to tune fan curves, frequency limits and cooling budgets. In short, the S21 is not merely a count of terahashes; it is a focused instrument for those who fold risk into models and long arcs of operation, a high-efficiency tool that rewards careful electrical design, thermal management and firmware stewardship while offering predictable throughput useful for yield modeling against network difficulty, energy profiles and expected service intervals.
