The Bitmain Antminer S21 (200Th), also known as the Antminer S21 200T, drives a steady 200 TH/s on the SHA-256 seam while drawing about 3550 W-roughly… 17.5 J/TH-its 5 nm ASICs and dual high-pressure fans working in tandem like a disciplined hive that exhales a small weather of heat, making it a formidable choice for mining Bitcoin, Bitcoin Cash, and Bitcoin SV; with front-to-back airflow, a compact steel-clad frame, and stable operation across 5–40°C and 5–95% non-condensing humidity, it is built for long-haul uptime, typically around 75–80 dB at 1 m and shedding approximately 12,100 BTU/h, so plan for ducting, filters, and hot/cold aisle separation to keep intake air clean and cool, and expect about 85.2 kWh of energy use per day at continuous load; deployment is straightforward-200–240 V AC on a dedicated circuit with headroom (commonly 20 A at 240 V), a high power factor PSU, grounded metal PDUs, and RJ45 Ethernet (10/100) with very modest bandwidth but low latency to your pool, plus a web interface for management, performance/efficiency modes, temperature and fan targets, and logs, with Stratum-compatible pools and firmware updates that can improve stability and sometimes efficiency; for profitability planning, combine the fixed hashrate with current network difficulty, block subsidy plus transaction fees, pool fee, uptime, and stale/reject rate, then account for energy use by multiplying 85.2 kWh/day (about 2.59 MWh/month) by your local electricity rate, and run scenarios that vary ambient temperature, fan policy, and efficiency mode to identify breakeven and margin, because heat, dust, and throttling steal more than numbers suggest; for reliability, periodically clear heat sinks and grills, avoid negative pressure that recycles exhaust into intake, maintain clean intakes with removable prefilters (mind backpressure), monitor chip temps to preempt thermal throttling (the unit will throttle or shut down at protective thresholds), and consider lightweight UPS for network gear rather than the miner itself, while ensuring good cable strain relief and secure connectors; bandwidth needs are low but consistent-stable wired Ethernet is preferable to Wi‑Fi-and a static reservation can simplify fleet management; placed correctly, the machine’s granular hum becomes a steady, decipherable metric of health, reminding you that efficient mining is equal parts arithmetic and habitat design.

Bitmain Antminer S21 — In Detail
Bitmain Antminer S21 (200TH/s) — a closer look at the hardware and how it performs.
The Bitmain Antminer S21 (200Th), also listed as the Antminer S21 200T, threads its 5 nm ASICs into a steady 200 TH/s on SHA‑256 while drawing roughly… 3,550 W for about 17.5 J/TH, its front‑to‑back dual‑fan cooling and dense fin heat sinks holding the line against thermal drift so the unit hums along, steady as a courthouse clock; firmware auto‑tunes frequency and voltage by temperature, offers watchdog recovery, pool failover, and selectable performance/efficiency profiles, and pairs with Bitmain’s API and web interface for batch provisioning, real‑time diagnostics down to hashboard sensors, and over‑the‑air updates; the integrated PSU brings reinforced protections against surges, overcurrent, and overvoltage events to curb spike‑related faults, and the aluminum‑alloy shell helps tamp electromagnetic noise so fleet neighbors don’t quarrel for signal in crowded racks; built for Bitcoin, Bitcoin Cash, and Bitcoin SV, it expects wired RJ45 Ethernet (10/100), Stratum‑compatible pools, and low latency more than high bandwidth, with DHCP or static addressing both supported; acoustics typically sit in the mid‑70s dB at 1 m and waste heat lands near 12,100 BTU/h at full tilt, so plan clear intake paths, straight exhaust routes, and filtration that won’t starve airflow, because dust and recirculation will find you like summer cicadas; continuous operation spans 5–40°C and 5–95% non‑condensing humidity, daily energy use is roughly 85 kWh at full load, and best practice is a dedicated 200–240 V AC circuit with headroom, grounded metal PDUs, and secure cable strain relief; for uptime, keep grills and sinks clean, monitor chip and inlet temperatures to preempt throttling or protective shutdown, avoid negative pressure that drags exhaust forward, and use multiple pool entries for failover; compact and sturdy for standard racking, the S21’s aluminum shell, remote controls, and protective power design make it a dependable SHA‑256 workhorse whose quiet grammar is data-hashrate, temperature, fan speed-easy to read if you keep its habitat orderly.

The algorithm
Algorithm Information: SHA-256
SHA-256 — what this algorithm is and how it works.
SHA-256 is a cryptographic hash function. NiceHash relies on it for proof-of-work consensus. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.

Based on our real-time ASIC mining profit calculation, the Bitmain Antminer S21 is currently most profitable mining NiceHash at your electricity rate of $0.080/kWh. This can change as coin prices and network difficulty shift, so check the Mineable Coins table above for the latest ranking.
This ASIC mining profit calculation for the Bitmain Antminer S21 uses live cryptocurrency prices, current network difficulty, and block rewards for every supported coin, combined with your custom electricity rate. Figures update automatically as network conditions change, so the profitability shown reflects current conditions rather than a static estimate.
NiceHash is a hashpower marketplace, not a traditional mining pool — instead of mining a coin directly, you sell your Bitmain Antminer S21 hashrate to buyers and get paid in Bitcoin. Compare the NiceHash row against direct-mining rows in the Mineable Coins table above: whichever shows the higher Profit/Day at your electricity rate is currently the better option for this specific miner.
This miner is not currently listed by any of our verified vendors. You can still use the profitability figures on this page to plan ahead for when new listings appear.
