Bitmain Antminer S23 Hyd 3U 1.16 PH/s SHA-256 Bitcoin Miner

1.16 PH/s (1,160 TH/s) of SHA-256 hashrate at 11,020W continuous power draw and 9.5 J/TH efficiency. Bitmain's ±3% hashrate tolerance means real world output ranges 1,125 to 1,195 TH/s. ±5% power tolerance means wall draw can reach 11,571W at peak. This matches the standalone S23 Hydro 580TH on per terahash efficiency while doubling per unit hashrate through the 3U form factor. Bitmain's most powerful current Bitcoin miner and the first production hardware to cross the petahash barrier in a single chassis.

Yes, 9.5 J/TH is near the top of current-generation silicon. Within Bitmain's hydro line it leads: the S21 XP Hydro 473TH runs at 12 J/TH, about 26 percent less efficient, the S21+ Hydro 395TH at 15 J/TH, and the air-cooled S23 at 11 J/TH. Efficiency is the single biggest lever on operating cost at scale, since every point of J/TH multiplies across 1,160 TH/s running 24 hours a day. Moving a fleet from 12 J/TH hardware to the S23 Hyd 3U cuts energy per terahash by roughly a fifth, which is why efficiency, not upfront cost, decides long-run economics for high-power deployments.

Form factor and hashrate density. S23 Hyd 3U (this product): 1,160 TH/s at 11,020W in a 3U rack mount chassis (900 x 486 x 132 mm, 21.5 kg). S23 Hydro 580TH: 580 TH/s at 5,510W in a compact standalone chassis (410 x 170 x 209 mm, 13.5 kg). Both deliver identical 9.5 J/TH efficiency. The 3U variant doubles hashrate per unit at double power draw, enabling rack consolidation and management overhead reduction. The standalone variant fits shelf or compact rack deployment at lower per unit cost. Choose based on facility rack infrastructure, aggregate hashrate targets, and management preferences across fleet size.

380 to 415V three phase industrial power service through an LP34 industrial connector (Bitmain's specified connector standard for this hardware). At 415V three phase: approximately 15 amps per phase continuous, 25 amps per phase at peak. At 380V three phase: approximately 17 amps per phase continuous. Requires dedicated 32 amp three phase breakers minimum. LP34 connector excludes standard commercial single phase or residential deployment entirely. This is strictly industrial hardware for professional data center and dedicated mining facility deployment. Facilities without three phase industrial electrical distribution cannot support this unit directly.

External closed loop water cooling system with substantial thermal capacity. Each unit generates approximately 11 kW thermal load (37,520 BTU per hour), requiring circulation pumps sized for fleet flow rate, dry cooler or water to water heat exchanger rated for total thermal load, inline particulate filtration, automated flow monitoring, and temperature management at inlet and outlet points. Critical constraint: inlet water temperature must remain above 20 degrees Celsius for miner startup (hardware protection interlock). Maximum facility ambient temperature scales with outlet water temperature per Bitmain's published curves. Multi unit deployments scale cooling infrastructure proportionally through manifold distribution with individual unit isolation valves for maintenance.

On raw hashrate, one S23 Hyd 3U at 1.16 PH/s replaces about 12 Antminer S19-class units at roughly 100 TH/s each, 4 S21 XP 270TH air-cooled units, 2 S23 Hydro 580TH units, or about 2.5 S21 XP Hydro 473TH units. The consolidation matters beyond hashrate: fewer Ethernet connections, fewer water fittings, fewer PSU cables, a lower aggregate cable-failure rate, and fewer firmware endpoints. For facilities running multi-megawatt operations, compressing petahash capacity into a single 3U slot per unit simplifies fleet management far more than maintaining dozens of lower-output machines.

42U rack holds 14 units at 3U each, producing 16.24 PH/s per cabinet at 154 kW total. 100 kW industrial electrical panel: approximately 9 units producing 10.44 PH/s aggregate. Compare alternatives. 100 kW of S23 Hydro 580TH standalone: 18 units producing 10.44 PH/s (identical aggregate, different form factor and unit count). 100 kW of S21 XP Hydro 473TH: 17 units producing 8.04 PH/s (23 percent less aggregate). 100 kW of S21+ Hydro 395TH: 17 units producing 6.72 PH/s (36 percent less aggregate). Per megawatt industrial panel: approximately 90 S23 Hyd 3U units producing 104 PH/s aggregate at current generation efficiency.

Any SHA-256 proof of work cryptocurrency. Bitcoin (BTC) is the primary target. Other compatible coins include Bitcoin Cash (BCH), Bitcoin SV (BSV), Fractal Bitcoin (FB), Namecoin (NMC), DigiByte (DGB SHA-256 chain). Merged mining BTC alongside BCH and BSV through supporting pools (ViaBTC, F2Pool) adds marginal secondary revenue without reducing Bitcoin hashrate contribution.

No. The 11,020W power draw requires 380 to 415V three phase industrial electrical service with LP34 industrial power connector, unavailable in residential settings. The 11 kW thermal load requires substantial external water cooling infrastructure impractical for residential installation. The 21.5 kg chassis weight and 900 mm depth require industrial grade rack hardware. This is strictly industrial hardware for professional mining facilities, commercial data centers, and dedicated hosting operations. For home deployment seeking hydro cooling, the Antminer S21+ Hydro 395TH with 100 to 240V universal single phase voltage represents the residential ceiling for hydro deployment.

S23 Hyd 3U profitability depends on the Bitcoin price, network difficulty, and your electricity rate, not on any fixed figure. At 11,020W, power cost is the dominant lever on net return, so the unit performs best on the sub-five-cent industrial and hosted rates it was built for, and its class-leading 9.5 J/TH efficiency holds margin better than older hardware as difficulty rises. Because coin price and difficulty move constantly, any daily figure is out of date within days. Run your own electricity rate through MillionMiner's live calculator for a current estimate, or ask about hosting for lower industrial power.

50 dB chassis noise, which is effectively silent due to the absence of high speed cooling fans. The external cooling infrastructure generates acoustic signature separately: pumps typically run 45 to 55 dB, dry coolers and circulation plants typically run 55 to 70 dB depending on airflow requirements and physical design. Professional hydro cooled mining facilities specifically isolate miner deployment space from cooling plant locations to minimize acoustic impact. Total deployment noise depends on cooling infrastructure design rather than miner chassis. For industrial facilities with dedicated cooling plant rooms separated from mining deployment, operating noise in the miner room typically runs below 60 dB.

Industrial deployment with three phase power, LP34 connectors, and hydro cooling infrastructure. Step one: install dedicated 380 to 415V three phase electrical service with LP34 industrial connectors and 32 amp three phase breakers minimum. Step two: install and commission external hydro cooling loop with pumps, plumbing, coolant fill, dry cooler or heat exchanger rated for total thermal load, and temperature monitoring. Verify inlet water temperature capability above 20°C year round. Step three: rack mount S23 Hyd 3U units in 19 inch server racks (verify rack depth accommodates 900 mm chassis). Connect water inlet/outlet fittings to manifold system with individual isolation valves. Verify zero leaks before energizing. Step four: connect LP34 power cables and Ethernet management. Step five: power on, allow coolant flow to stabilize with inlet above 20°C, find miner IP through DHCP, configure pool URL and Bitcoin wallet through Bitmain web interface, verify hashrate reaches 1,125+ TH/s within 15 to 20 minutes per unit.

Industrial hydro cooling maintenance with emphasis on temperature management and water quality. Weekly visual inspection of water fittings for leaks. Monthly coolant quality testing. Every 12 to 24 months full coolant replacement. Quarterly pump and dry cooler inspection including flow rate verification. Inline filter replacement when pressure differential exceeds specification. Hashboard failure rates on hydro units run meaningfully lower than air cooled equivalents because chips operate at consistent temperatures. Temperature sensor calibration checks semi annually to ensure the 20°C inlet constraint operates correctly. LP34 connector inspection quarterly for corrosion or damage. Budget 3 to 5 percent of acquisition cost annually for maintenance reserves.

Bitmain 365 day factory warranty 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. Document coolant testing schedule, inlet temperature logs, and maintenance records to protect warranty coverage. MillionMiner routes warranty claims through direct Bitmain channels.

Yes. MillionMiner operates managed hosting facilities with 380 to 415V three phase industrial power, LP34 industrial connectors, and hydro cooling infrastructure capable of supporting S23 Hyd 3U deployments. Hosted deployment eliminates facility infrastructure CapEx (three phase electrical service, LP34 industrial connectors, hydro cooling loop installation, dry cooler infrastructure) and leverages MillionMiner's negotiated industrial electricity rates typically $0.04 to $0.06 per kWh. At these hosted rates, OneMiners documents $68 to $95 daily earnings per unit during April to August 2025 operational data.

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 10 PH/s (equivalent to 9+ units or a single 100 kW panel), direct negotiated agreements with major pools typically secure reduced fees below standard 1 to 2 percent rates. At fleet scale above 50 PH/s, private pool arrangements become viable.

CapEx beyond miner acquisition: three phase electrical service with LP34 connectors ($10,000 to $30,000 per facility installation), hydro cooling loop with dry cooler infrastructure ($10,000 to $40,000 per rack depending on capacity), industrial rack hardware ($2,000 to $5,000 per rack), temperature monitoring systems. Annual OpEx per unit at 11,020W continuous: electricity at $7,725 at $0.08 per kWh, $6,759 at $0.07 per kWh, $3,862 at $0.04 per kWh industrial hosting rates. Water glycol coolant maintenance ($200 to $500 annually per unit at scale). Spare parts reserves (3 to 5 percent of acquisition annually). 3 year TCO per unit at $0.07 per kWh self hosted: approximately $32,379 hardware plus $20,277 electricity plus $1,500 maintenance equals $54,156 total. 3 year gross revenue at $0.07 per kWh profitability: $27,000 to $40,000.

Yes, verify before ordering. Standard 19 inch server racks come in multiple depth variants: 600 mm, 750 mm, 900 mm, 1000 mm, and 1200 mm commonly. The S23 Hyd 3U at 900 mm chassis depth requires minimum 1000 mm rack depth for proper cable management clearance, and 1200 mm rack depth provides comfortable cable and cooling management access. Most data center and dedicated mining facilities use 1000 mm or 1200 mm racks. Smaller 600 mm or 750 mm racks cannot accommodate this hardware. Check facility rack inventory and specifications before committing to large fleet orders.

Bitmain announced the S23 Hyd 3U in mid-2025, with batch shipping beginning in early 2026 and subsequent batches continuing through the year. MillionMiner inventory reflects the current shipping batch, with factory shipment typically within 5 to 10 business days for standard orders, while bulk deployments coordinate with Bitmain's production schedule. Because this is a new flagship shipping in batches, availability and lead time shift over time, so confirm the current batch and delivery window at order. Every unit ships DDP worldwide with customs handling included.

Within the Bitmain S23 generation, the S23 Hydro 580TH standalone offers a lower per-unit entry at the same efficiency, the air-cooled S23 318TH suits sites without hydro infrastructure, and the S23 Immersion 442TH fits tank deployments. In the S21 hydro line, the S21 XP Hydro 473TH and S21+ Hydro 395TH are alternatives where three-phase infrastructure is limited. For algorithm diversification, MillionMiner also stocks the Antminer KS7 for Kaspa and L11 for Litecoin and Dogecoin merged mining. MillionMiner's ASIC hosting service accepts S23 Hyd 3U units with full three-phase and hydro cooling infrastructure included.
