Released February 2024. This is the base tier of the S21 generation hierarchy that also includes the S21 PRO (234 TH/s), S21+ (235 TH/s), and S21 XP (270 TH/s).

How does the S21 compare to the S21 PRO?

S21 PRO đạt 234 TH/s tiêu thụ 3.510W và 15 J/TH với giá 3.083 USD, trong khi S21 cơ bản đạt 200 TH/s tiêu thụ 3.550W và 17.5 J/TH với giá 1.402 USD đã qua sử dụng hoặc 1.755 USD Plug and Play. PRO tạo ra lượng hash cao hơn 17% với hiệu quả tốt hơn 17%, mang lại lợi ích cao hơn từ 76 đến 120% về CapEx. Ở mức giá điện 0,08 USD/kWh, S21 cơ bản tạo lợi nhuận hàng ngày +0,75 USD so với PRO là +1,87 USD. Lợi nhuận hàng ngày của PRO bù đắp khoản vượt trội về CapEx so với S21 cơ bản trong khoảng từ khoảng 3,2 đến 4,1 năm. Đối với các dự án triển khai ngắn hạn hoặc nhà vận hành có điện giá rẻ, S21 cơ bản chiến thắng về hiệu quả CapEx. Trong các dự án dài hạn hoặc sử dụng điện đắt đỏ, hiệu quả của PRO tích tụ thành tiết kiệm có ý nghĩa.

How does the S21 compare to the S21 XP?

S21 XP cung cấp 270 TH/s với 3.645W và 13,5 J/TH với giá 4.051 đô la, trong khi phiên bản cơ sở S21 cung cấp 200 TH/s với 3.550W và 17,5 J/TH với giá 1.402 đô la đã qua sử dụng hoặc 1.755 đô la Plug and Play. S21 XP sản xuất nhiều hơn 35% hashrate với hiệu quả tốt hơn 23% so với phiên bản cơ sở, đem lại lợi nhuận CapEx tăng từ 131 đến 189%. Ở mức giá điện 0,08 đô la/kWh, S21 cơ sở mang lại lợi nhuận ròng hàng ngày +0,75 đô la so với XP là +3,81 đô la hàng ngày. XP là lựa chọn cao cấp với hiệu quả kinh tế rõ rệt hơn ở bất kỳ mức giá điện nào. Sở hữu S21 cơ sở là bước đầu tư phù hợp với ngân sách. Người mua so sánh giữa chi phí CapEx và OpEx: tiết kiệm được từ 2.296 đến 2.649 đô la cho mỗi đơn vị khi mua S21 cơ sở, nhưng chấp nhận lợi nhuận ròng khoảng 3 đô la ít hơn hàng ngày cho mỗi đơn vị.

What voltage does the S21 need?

200 to 240V AC single phase at 20A maximum current via P13-C20 power cord. At 3,550W the unit draws approximately 16 amps continuous at 220V. Compatible with 220V residential outlets used for electric dryers and ovens, 240V commercial service, or industrial 220 to 277V service. Requires dedicated 20A circuit. Commercial 220V+ circuits required for deployment. Verify electrical service at the deployment site before purchasing if 220V is not already available.

Should I buy Used or Plug and Play Ready?

Used at $1,402.23 is $352 cheaper than Plug and Play Ready at $1,755, a 25 percent premium for the verified configuration. Used units may have cosmetic wear, potentially reduced remaining warranty, and should be inspected before production deployment. Plug and Play Ready units are tested and verified for immediate deployment with the full 365-day Bitmain factory warranty. For buyers with technical expertise willing to inspect hardware, verify hashrate stability, and potentially refurbish components, the Used option produces $7.01 per terahash acquisition cost. For buyers prioritizing immediate deployment with full warranty coverage and minimum technical friction, Plug and Play Ready at $8.78 per terahash is the safer path.

Is the S21 profitable?

Profitable at industrial and low residential electricity rates, marginal at typical residential rates. MillionMiner calculator at $0.08 per kWh shows +$0.75 daily profit, +$22.50 monthly, +$274 annually. Mining Now at $0.07 per kWh shows +$1.23 daily, +$36.90 monthly, +$448.95 annually. At $0.05 per kWh industrial hosting rates: approximately +$2.78 daily, +$83 monthly, +$1,014 annually. Break even electricity rate at current Bitcoin pricing is approximately $0.085 per kWh. Payback at Used pricing and $0.08 per kWh is approximately 5.1 years; at $0.05 per kWh approximately 1.4 years. The S21 base is positioned for CapEx-efficient deployment at industrial electricity access, not for profit maximization at residential rates.

75 dB from four cooling fans at peak operation. Standard industrial ASIC noise comparable to a vacuum cleaner or busy restaurant. Same noise profile as the S21 PRO, S21 XP, S23, and most current generation air cooled Bitcoin miners. Requires dedicated mining space: warehouse, shipping container, garage with sound isolation, dedicated outbuilding, or professional hosting facility. Not suitable for shared residential spaces, apartments, or offices with neighboring occupants. Fan RPM and therefore noise scales with ambient temperature: deployment in hotter environments produces higher noise as fans work harder to maintain chip temperatures.

How big and heavy is the S21?

400 x 195.5 x 290 mm miner dimensions at 13.5 kg net weight. Standard Antminer chassis format compatible with existing S19 and S21 series rack configurations and mining shelves. Single person handling with appropriate lifting technique. Fits standard 4U rack mount configurations or open mining shelving without specialized hardware. Packaged shipping weight approximately 17 kg including PSU and packaging materials.

Phạm vi nhiệt độ hoạt động là gì?

Phạm vi hoạt động môi trường từ 5 đến 45 độ C với mức độ ẩm từ 5 đến 95 phần trăm theo tài liệu chính thức của Bitmain. Nhiệt độ tối đa hoạt động giảm 1°C mỗi 300 mét độ cao tăng thêm trên 900 mét theo hướng dẫn độ cao của Bitmain. Đối với việc triển khai trong các khí hậu nóng như UAE, mùa hè Texas, Arizona hoặc các vùng nhiệt đới, hạ tầng làm mát môi trường phải giữ không khí vào trong dưới khoảng 40°C ở tải đỉnh để duy trì tốc độ băm ổn định. Tốc độ quạt tăng đáng kể khi nhiệt độ môi trường gần tới giới hạn trên 45°C, gây tiếng ồn và giảm tuổi thọ của các thành phần.

Tôi có thể khai thác những loại tiền nào với S21?

All SHA-256 proof of work cryptocurrencies. Bitcoin (BTC) is the primary target. Bitcoin Cash (BCH), Bitcoin SV (BSV), eCash (XEC), Fractal Bitcoin (FB), and other SHA-256 chains are also mineable. AuxPoW merged mining is available through compatible pools such as RSK (Rootstock) alongside Bitcoin, providing supplementary rewards at zero additional hashrate cost. Most operators mine Bitcoin directly at major pools for maximum revenue stability. Alternative SHA-256 chains occasionally deliver higher per-hashrate revenue during specific market conditions, making pool-switching strategies viable for operators with flexible configurations.

Does the PSU come included?

Yes. The S21 ships with an included PSU sized for the 3,550W rated load, along with the P13-C20 power cord. Box contents per MillionMiner: Antminer S21 unit, power supply unit (PSU), power cables, and quick start guide. Contents may vary by batch, with exact items listed in order confirmation. The included PSU eliminates external power brick sourcing decisions and connector compatibility concerns. PSU inclusion may vary between Used and Plug and Play Ready configurations; verify at purchase if running a multi-unit deployment plan.

How do I set up the S21?

Standard Antminer setup. Step one: verify 220 to 240V electrical circuit with 20A capacity at the deployment location. Step two: connect the included P13-C20 power cord to the integrated PSU and plug into the 220V+ outlet. Step three: connect Ethernet cable to the router or network switch. Step four: find miner IP through Bitmain IP Reporter software, router DHCP assignment table, or network scanning tool. Step five: open the Antminer web interface in a browser, login with default root/root credentials (change immediately for security), configure SHA-256 pool URL and BTC wallet address. Step six: verify hashrate stabilizes at approximately 200 TH/s within 10 to 15 minutes of startup.

Which pools support the S21?

Every major SHA-256 mining pool supports the S21: Foundry USA, AntPool, F2Pool, ViaBTC, Braiins Pool, Luxor, OCEAN, SpiderPool, EMCD, and all other SHA-256 compatible pools. Standard Stratum protocol with no hardware restrictions on pool selection. Pool fees typically range from 0 to 3 percent of revenue depending on pool business model. NiceHash supports the S21 for hashrate rental marketplace sellers who prefer rental income over direct mining rewards. Verify pool specifics before deployment including minimum payout thresholds, hashrate reporting accuracy, and any minimum hashrate requirements.

What warranty does the S21 have?

365-day Bitmain factory warranty on brand new Plug and Play Ready units, among the longest warranties in the ASIC mining industry. Most competing manufacturers offer 180 days. Warranty covers manufacturing defects and hardware failures under normal operating conditions. Tampering with the warranty seal, use of incompatible PSU, exceeding rated voltage input, or physical damage from shipping voids coverage. Used configuration warranty terms vary depending on the unit's remaining factory warranty period and distributor policies; verify at purchase with MillionMiner. Warranty claims processed through MillionMiner support with direct Bitmain channel escalation as needed.

What maintenance does the S21 require?

Standard air cooled Antminer maintenance. Quarterly dust cleaning of the four fan intakes and rear exhaust prevents thermal throttling and premature fan bearing wear. Annual fan bearing inspection with replacement if bearing noise develops. Monitor hashrate continuously through the Antminer web interface or BraiinsOS+ dashboard. Bitmain's S21 platform has two years of field reliability data as of April 2026 with no known systemic reliability issues. For Used unit operators, add initial inspection of chassis for signs of thermal stress, verify PSU capacitor health if possible, run 24-hour burn-in at rated load before production deployment, and test all four fans under load to confirm functional cooling.

Can MillionMiner host the S21?

Yes. MillionMiner hosting services accept S21 series hardware at managed facilities with 220V+ electrical infrastructure. At $0.07 per kWh hosted electricity: +$1.23 daily profit at current Bitcoin pricing. At $0.05 per kWh industrial hosting rates: approximately +$2.78 daily profit. Hosting eliminates facility CapEx, noise management, thermal infrastructure, and day-to-day operational overhead. For first time Bitcoin mining buyers without 220V circuits, dedicated deployment space, or 75 dB-tolerant mining location, hosting through MillionMiner is often the practical path to operational Bitcoin mining. Contact MillionMiner for current hosting rates, power tier options, and facility availability.

Bitmain Antminer S21 200 TH/s SHA-256 Air Cooled Bitcoin Miner: The Base Tier S21 Generation Model With BM1368 5nm Chip Architecture and the Lowest CapEx Entry in the S21 Family

The Bitmain Antminer S21 produces 200 TH/s of SHA-256 hashrate at 3,550W wall draw and 17.5 J/TH efficiency on Bitmain's BM1368 5nm chip architecture, released February 2024. ±3 percent hashrate and ±5 percent power tolerance per Bitmain documentation. Four cooling fans at 75 dB industrial noise. 200 to 240V AC single phase input at 20A maximum current via P13-C20 power cord. 400 x 195.5 x 290 mm miner dimensions at 13.5 kg. Ethernet 10/100M connectivity. 5 to 45 degrees Celsius operating range at 5 to 95 percent humidity tolerance. 365-day Bitmain factory warranty on Plug and Play Ready units. Available at MillionMiner in two configurations: Used at $1,402.23 or Plug and Play Ready at $1,755. S21 family hierarchy with current MillionMiner pricing. Standard S21 at 200 TH/s, 3,550W, 17.5 J/TH, $1,402.23 Used or $1,755 Plug and Play (this product, base tier entry). S21 PRO at 234 TH/s, 3,510W, 15 J/TH, $3,083 (premium chip bin with 17 percent more hashrate at 17 percent better efficiency). S21+ at 235 TH/s, 3,876W, 16.5 J/TH (mid bin, hashrate comparable to PRO but 10 percent worse efficiency). S21 XP at 270 TH/s, 3,645W, 13.5 J/TH, $4,051 (top premium bin with maximum hashrate and efficiency). Above the S21 family, the S23 generation at 318 TH/s and 11 J/TH ($8,103) introduces Bitmain's next chip generation with substantial efficiency improvement. Hydro cooled variants include the S21+ Hyd at 319 TH/s ($3,137) and S21 XP Hydro at 473 TH/s ($6,899). BM1368 chip architecture context. The S21 family introduced Bitmain's BM1368 chip in early 2024, replacing the BM1362 used in the S19 XP generation. The BM1368 is a 5nm process chip manufactured by TSMC delivering approximately 19 percent efficiency improvement over the 7nm BM1362 (S19 XP at 21.5 J/TH versus S21 at 17.5 J/TH). The BM1368 architecture is the foundation across S21, S21+, S21 PRO, and S21 XP, with silicon binning determining which tier each wafer populates. The base S21 receives standard production bin chips. The S21 PRO receives chips that achieve higher frequency at lower voltage, enabling 234 TH/s at 3,510W from the same chassis design. The S21 XP receives the top premium bin enabling 270 TH/s. No physical hardware difference exists between S21 tiers beyond silicon quality selection. Fleet economics math for the CapEx versus OpEx trade off. At fleet scale of 100 units, base S21 produces 20,000 TH/s total at 355 kW continuous. The S21 PRO fleet produces 23,400 TH/s at 351 kW. The PRO fleet produces 17 percent more Bitcoin at essentially the same total power consumption. The CapEx difference is meaningful: $175,500 for 100 Plug and Play base S21 units versus $308,300 for 100 S21 PRO units, a $132,800 premium for the PRO fleet. At $0.08 per kWh: base S21 fleet produces +$75 daily, PRO fleet produces +$187 daily. The PRO fleet produces $112 more daily profit, paying back the $132,800 CapEx premium in approximately 3.3 years. For operators with short deployment horizons, cash-constrained scaling, or uncertain electricity contracts, the base S21 is the correct choice. For operators with longer commitments and expensive electricity, the S21 PRO pays back through efficiency savings over time. Used versus Plug and Play Ready pricing decision analysis. MillionMiner offers two distinct configurations at different price points. Used at $1,402.23: second-hand units with potential cosmetic wear, potentially reduced remaining manufacturer warranty, and unverified operating history. Buyers should budget time for inspection, firmware updates, hashrate verification, and possible PSU or component replacement before production deployment. Plug and Play Ready at $1,755: tested and verified for immediate deployment with cleaner provenance and full 365-day Bitmain factory warranty. The $352 price gap reflects the practical value of deployment-ready hardware versus hardware requiring buyer inspection. Per terahash math: Used at $7.01 per TH, Plug and Play at $8.78 per TH. Both configurations sit well below the S21 PRO at $13.17 per TH and S21 XP at $15 per TH, making the base S21 the CapEx-efficient entry point across the entire S21 generation regardless of which configuration buyers select. Current economics in detail. MillionMiner calculator at $0.08 per kWh: $7.57 daily revenue, $6.82 daily electricity cost, +$0.75 daily profit, +$22.50 monthly, +$274 annually. At Used pricing $1,402.23 and $0.08 per kWh: payback approximately 5.1 years. Mining Now at $0.07 per kWh: +$1.23 daily, +$36.90 monthly, +$448.95 annually. At $0.05 per kWh industrial hosting rate: approximately +$2.78 daily, +$83 monthly, +$1,014 annually, payback at Used pricing approximately 1.4 years. At $0.04 per kWh: approximately +$3.55 daily, payback approximately 1.1 years. Break even electricity rate at current Bitcoin pricing is approximately $0.085 per kWh. Profitable below that threshold, substantially so at industrial rates. Economics scale linearly with Bitcoin price: a 20 percent BTC appreciation produces roughly 20 percent higher daily profit at constant electricity cost. Bitmain firmware ecosystem and optimization potential. The S21 runs Bitmain's mature Antminer firmware with comprehensive web interface management including pool configuration, hashrate monitoring, per-chip performance data, temperature alerting, fan speed control, and remote restart capability. Third party firmware including BraiinsOS+ and Vnish supports the S21 series for autotuning optimization that automatically finds optimal chip voltage and frequency for target efficiency. Operators using BraiinsOS+ autotuning on S21 hardware typically achieve 2 to 5 percent efficiency improvements over stock firmware, pushing the S21 from 17.5 J/TH toward 16.5 to 17 J/TH depending on chip quality and ambient conditions. The Antminer firmware ecosystem is the most developed in ASIC mining hardware, providing extensive community documentation, integration with major pool software including BraiinsPool and Foundry USA, and compatibility with existing Bitmain fleet management tools. For operators running mixed fleets of Bitmain hardware across S19, S21, and S23 generations, the S21 integrates into existing management infrastructure without retraining or workflow changes. (1,199 characters) Bitmain manufacturer context. Bitmain Technologies, founded in Beijing in 2013, is the largest ASIC mining hardware manufacturer by shipment volume and market share. The Antminer series has been the industry standard since the S7 era in 2015. Manufacturing scale, firmware maturity, distributor network breadth, and support infrastructure are unmatched among ASIC mining hardware companies. The S21 family benefits from Bitmain's established supply chain, RMA processes, and decade-plus field reliability history. The 365-day factory warranty on brand new units is among the longest in the industry (most manufacturers offer 180 days) and reflects Bitmain's confidence in chip quality and production standards. Ships from MillionMiner with miner, PSU, power cables, quick start guide, applicable warranty coverage based on configuration (365-day Bitmain factory warranty on Plug and Play Ready; Used warranty varies and should be verified at purchase), and free DDP worldwide delivery covering all customs clearance, import duties, and taxes.

PRO but 10 percent worse efficiency. S21 XP at 270 TH/s, 3,645W, 13.5 J/TH, top premium bin
with the best hashrate and efficiency in the family. All four tiers share the BM1368 chip
architecture, with performance differentiation coming from silicon binning across Bitmain's
production wafers. The base S21 receives the standard bin chips: reliable production silicon at
tested specifications, just not the premium frequency-per-volt selection that the PRO and XP
tiers receive. The Used versus Plug and Play Ready pricing decision. Used at $1,402.23 is $352 cheaper
than Plug and Play Ready at $1,755, a 25 percent premium for the verified configuration. Used
units typically carry cosmetic wear and potentially reduced remaining warranty. Plug and Play
Ready units are tested and verified for immediate deployment with the full 365-day Bitmain
factory warranty. Per terahash acquisition cost: Used at $7.01 per TH, Plug and Play at $8.78
per TH. The Used S21 is the cheapest per terahash entry to current generation Bitcoin mining
available in MillionMiner's inventory. For buyers with technical expertise willing to inspect
hardware before deployment, the Used option produces meaningful CapEx savings. For buyers
prioritizing immediate deployment with full warranty coverage, Plug and Play Ready is the
cleaner path. Current economics. MillionMiner calculator at $0.08 per kWh: $7.57 daily revenue, $6.82 daily
electricity, +$0.75 daily profit, +$22.50 monthly. Mining Now at $0.07 per kWh: +$1.23 daily,
+$36.90 monthly, +$448.95 annually. At $0.05 per kWh industrial hosting rate: approximately
+$2.78 daily, +$83 monthly. Profitable below approximately $0.085 per kWh at April 2026 Bitcoin
pricing, marginal above that threshold. The S21 base is positioned as a CapEx-efficient
deployment at industrial electricity access, not as a profit maximizer at residential electricity
rates. Bitmain firmware ecosystem context. The S21 runs Bitmain's mature Antminer firmware with
web interface management, pool configuration, hashrate monitoring, temperature alerting, and
fan control. Third party firmware including BraiinsOS+ and Vnish supports the S21 series for
autotuning optimization. Operators using BraiinsOS+ autotuning typically achieve 2 to 5 percent
efficiency improvements over stock firmware, pushing the S21 from 17.5 J/TH toward 16.5 to 17
J/TH. The Antminer firmware ecosystem is the most developed in ASIC mining hardware, with
extensive community documentation, integration with major pool software, and compatibility with
