Bitmain Antminer S21e XP Hyd (430TH)

430 TH/s of SHA-256 hashrate at 5,590W continuous power draw and 13 J/TH efficiency. Bitmain's ±3% hashrate tolerance produces real world output in the 417 to 443 TH/s range. Released November 2024, this is Bitmain's mid generation three phase hydro miner positioned between the S21+ Hydro 395TH (15 J/TH) and the S21 XP+ Hyd 500TH (11 J/TH) in the efficiency progression.

XP denotes Bitmain's extra performance tier within a generation. Bitmain typically releases base models, Plus (+) models with improved efficiency, Pro models with higher hashrate, and XP models representing the efficiency pinnacle of a generation. S21e XP represents the efficiency enhanced variant of the S21e hardware platform. Within the Bitmain naming convention: S21 (base), S21+ (efficiency improved), S21 XP (extra performance efficiency tier), S21e XP (enhanced variant of the XP). The XP suffix does not indicate current generation leadership given Bitmain's ongoing product releases, only the efficiency position within its own generation.

Mid tier efficiency in Bitmain's current hydro catalog. Current hydro progression: S21+ Hydro at 15 J/TH, S21e XP Hyd at 13 J/TH (this product), S21 XP Hydro at 12 J/TH, S21 XP+ Hyd at 11 J/TH, S23 Hydro at 9.5 J/TH. At $0.07 per kWh industrial rates, each J/TH efficiency point translates to approximately $28 per TH per year in electricity costs. Across 430 TH/s per unit, switching from 13 J/TH to 9.5 J/TH (S23 Hydro) saves approximately $4,200 annually in electricity per unit. The efficiency gap compounds meaningfully over multi year deployment.

380 to 415V three phase industrial power service. No universal voltage compatibility, unlike the S21+ Hydro and S21 XP Hydro siblings which accept 100 to 240V single phase. At 415V three phase: approximately 11 amps per phase continuous at 5,590W. At 380V: approximately 13 amps per phase continuous. Fits 16 amp three phase breakers with headroom. The three phase requirement restricts deployment to industrial facilities and commercial data centers, excluding standard single phase commercial or residential service.

External closed loop water cooling system with standard industrial components. Each unit generates approximately 5.59 kW thermal load (19,068 BTU per hour). Circulation pumps sized for fleet flow rate, dry cooler or water to water heat exchanger rated for aggregate thermal load, inline particulate filtration, automated flow monitoring. Compatible with water or water glycol closed loop configurations. Same cooling infrastructure requirements as the S21 XP Hydro, S21 XP+ Hyd, and S23 Hydro standalone hydro variants. No dielectric fluid or immersion tank required.

339 x 173 x 207 mm chassis at 13.8 kg. Identical form factor to the S21 XP Hydro 473TH and S21 XP+ Hyd 500TH standalone hydro variants. Fits standard shelves, compact rack configurations, or dedicated 19 inch server racks depending on facility design. Compact form factor enables dense deployment in facilities with space constraints. Does not require specialized 3U rack mount hardware of the S21e XP Hyd 3U or S23 Hyd 3U variants.

50 dB chassis noise, effectively silent due to the absence of cooling fans. External cooling infrastructure generates separate acoustic signature: pumps typically 45 to 55 dB, dry coolers typically 55 to 70 dB depending on equipment selection. Professional hydro cooled mining facilities isolate miner deployment from cooling plant locations to manage total acoustic footprint.

MillionMiner $0.08 per kWh onsite calculator: $14.55 daily revenue, $10.73 electricity, $3.82 daily net. ASIC Miner Value at $0.10 per kWh: $1.07 daily profit (marginal at residential rates). LeedMiner November 2025 at $0.045 per kWh: $15.08 daily revenue, $6.04 electricity, $9.04 daily net profit. OneMiners at $0.04 per kWh hosting: $13 to $18 daily earnings, averaging $15.50, with 19 to 26 month ROI. Economic viability favors industrial hosting rates below $0.05 per kWh.

Acquisition cost savings. MillionMiner pricing: S21e XP Hyd 430TH at $6,899, S21 XP+ Hyd 500TH at $9,500. The $2,601 per unit savings compounds meaningfully at fleet scale. For a 10 unit deployment, $26,010 acquisition cost savings on the S21e XP. At $0.04 per kWh industrial hosting over 3 year deployment, the efficiency gap (13 versus 11 J/TH on S21 XP+ Hyd) produces approximately $1,200 per unit in electricity savings on the newer hardware. Across 10 units, $12,000 electricity savings offsets half the S21 XP+ acquisition premium. Standard bin economics: S21e XP Hyd wins capital efficiency at low electricity rates and short horizons. S21 XP+ Hyd wins at higher rates and longer horizons.

No. The 380 to 415V three phase power requirement excludes residential electrical service in most regions. The 5.59 kW thermal load requires external water cooling infrastructure impractical for residential installation. The three phase requirement specifically excludes this unit from home deployment scenarios. For home hydro deployment, the Antminer S21+ Hydro 395TH with universal 100 to 240V single phase voltage represents the residential ceiling option.

Bitmain 365 day factory warranty per BT-Miners documentation on the complete machine covering manufacturing defects and hardware failures under normal operation within specified environmental ranges. Warranty exclusions include damage from coolant quality neglect, leaks caused by improper fitting installation, physical damage during cooling loop maintenance, power surge damage from inadequate electrical protection, operation outside specified environmental ranges, and unauthorized firmware modifications. Some distributors document 6 month warranty or 12 month variations. Verify current warranty terms with MillionMiner at time of purchase.

Industrial deployment with three phase power and hydro cooling infrastructure. Step one: install dedicated 380 to 415V three phase electrical service. Step two: install and commission external hydro cooling loop with pumps, plumbing, coolant, dry cooler infrastructure. Step three: shelf or rack mount the S21e XP Hyd units. Connect water inlet/outlet fittings to manifold system. Verify zero leaks before energizing. Step four: connect three phase power cables and Ethernet. Step five: power on, allow coolant flow to stabilize, find miner IP through DHCP, open Bitmain web interface, configure pool URL and Bitcoin wallet, verify hashrate reaches 417+ TH/s within 10 to 15 minutes.

Any Stratum compatible Bitcoin pool. Foundry USA leads by network hashrate share. F2Pool has the longest operational track record. AntPool is the native Bitmain ecosystem pool with deep firmware integration. ViaBTC offers accumulation mode payouts. Luxor supports hashrate derivatives products. For fleet deployments above 5 PH/s (equivalent to 12+ units), direct negotiated agreements with major pools typically secure reduced fees.

Yes. Braiins OS+ supports the S21e series with autotuning capabilities that can improve efficiency by 5 to 12 percent through per chip frequency optimization versus stock Bitmain firmware. Vnish and LuxOS also support S21e hardware with similar tuning capabilities. Third party firmware typically requires paid licenses ($2 to $5 per TH per year) but the efficiency gains often offset the license cost at industrial scale. Third party firmware voids Bitmain warranty, so operators typically run stock firmware during warranty period and consider third party firmware after warranty expiration.

CapEx beyond miner acquisition: three phase electrical service installation ($5,000 to $20,000 per facility), hydro cooling infrastructure ($5,000 to $20,000 per rack), rack hardware. Annual OpEx per unit at 5.59 kW continuous: electricity at $3,917 at $0.08 per kWh, $3,427 at $0.07 per kWh, $1,958 at $0.04 per kWh industrial hosting. Water glycol coolant maintenance and spare parts reserves. 3 year TCO per unit at $0.07 per kWh self hosted: approximately $6,899 hardware plus $10,281 electricity plus $800 maintenance equals $17,980 total. 3 year gross revenue at $0.07 per kWh profitability: $5,400 to $8,200.

Same generation silicon, different chassis format. S21e XP Hyd 430TH (this product): 430 TH/s at 5,590W and 13 J/TH, compact standalone. S21e XP Hyd 3U 860TH: 860 TH/s at 11,180W and 13 J/TH, 3U rack format. Both share identical SEAL02 silicon efficiency tier. The 3U variant doubles hashrate per unit at double power draw, consolidating management overhead for dense deployments. Per dollar of hashrate: $16.04 per TH for standalone S21e XP Hyd versus $13.54 per TH for S21e XP Hyd 3U. The 3U variant wins on acquisition cost per TH and fleet density. Standalone wins on deployment flexibility (no 3U rack hardware required) and lower per unit power draw simplifying electrical infrastructure.
