Bitmain Antminer S23 Hydro (580TH)

580 TH/s of SHA-256 hashrate at 5,510W continuous power draw and 9.5 J/TH efficiency. Bitmain's ±3% hashrate tolerance means real world output ranges 563 to 597 TH/s. ±5% power tolerance means wall draw can reach 5,786W peak. This is the most efficient model in the S23 generation, beating the air cooled S23 (11 J/TH), S23 Immersion (12 J/TH), prior generation S21 XP Hydro (12 J/TH), and S21+ Hydro family (15 J/TH). First Bitmain SHA-256 unit to break the 500 TH/s threshold while maintaining sub 10 J/TH efficiency.

Industrial mining economics compound across deployment scale and time. At $0.07 per kWh industrial electricity, each efficiency point in J/TH translates to approximately $25 annual electricity cost difference per terahash of hashrate. Across a 10 unit S23 Hydro deployment producing 5.8 PH/s, switching from 12 J/TH hardware to 9.5 J/TH saves approximately $18,000 annually in electricity costs. Over 3 year deployment horizons, this compounds to $54,000 saved per 10 units just from efficiency improvement. For megawatt scale operations, efficiency leadership defines profitability against competitors running prior generation hardware.

Same efficiency, different form factor and density tier. S23 Hydro 580TH (this product): 580 TH/s at 5,510W and 9.5 J/TH in a compact 410 x 170 x 209 mm chassis at 13.5 kg. S23 Hyd 3U 1.16 PH/s: 1,160 TH/s at 11,020W and 9.5 J/TH in a 3U rack mount chassis. Both deliver identical per terahash efficiency. The 3U variant doubles hashrate per unit at double power draw, enabling higher density in 19 inch server rack deployment. The 580TH variant fits compact shelf or standard rack deployment without specific 3U rack hardware requirement. Choose based on facility rack infrastructure and per unit management preferences.

380 to 415V three phase industrial power. At 415V three phase: approximately 8 amps per phase continuous, 14 amps per phase at peak draw. At 380V three phase: approximately 8.7 amps per phase continuous. Fits within standard 16 amp three phase breakers with headroom. Three phase industrial service is typical in dedicated mining facilities, data centers, commercial industrial buildings, and professional hosting operations. Absent from most retail commercial space and all residential settings. Facilities without three phase electrical distribution cannot deploy the S23 Hydro directly. The S21+ Hydro 395TH family with 100 to 240V universal single phase compatibility remains the relevant alternative for such deployments.

Per Bitmain's operational specifications documented by BT-Miners: if inlet water temperature is below 20 degrees Celsius, the miner cannot start. This is a hardware protection interlock, not a performance recommendation. External dry cooler specifications further tie maximum facility ambient temperature to outlet water temperature: if outlet temperature is 35 degrees, maximum ambient temperature is 30 degrees. If outlet temperature is 45 degrees, maximum ambient is 40 degrees. Cooling loop design must account for these constraints across seasonal temperature variation, particularly in regions with cold winters (inlet water below 20°C won't start) or hot summers (ambient above cooling capacity causes thermal throttling or shutdown).

External closed loop water cooling system with controlled temperature management. Required components: circulation pumps sized for fleet flow rate, standard plumbing fittings with thread or quick disconnect couplings, water or water glycol coolant mixture, external heat rejection through dry coolers rated for total thermal load (approximately 5.5 kW per unit, 18,760 BTU per hour), inline particulate filtration, temperature monitoring at both inlet and outlet, and automated flow monitoring. Multi unit deployments typically use manifold distribution with individual unit isolation valves for maintenance access. Budget $5,000 to $20,000 per rack for hydro cooling infrastructure depending on fleet size and existing facility capability.

50 dB chassis noise, which is effectively silent given the absence of high speed cooling fans. The external cooling infrastructure generates acoustic signature separately. Pumps typically run 45 to 55 dB depending on equipment selection. 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 on mining operations. Total deployment noise depends substantially on cooling infrastructure design rather than miner chassis.

Generally no. The 380 to 415V three phase power requirement is absent from residential electrical service in most regions. Additionally, the water cooling infrastructure requirements (circulation pumps, dry coolers, temperature managed loop, 20°C minimum inlet constraint, leak risk assessment) make home deployment impractical for most operators. Some advanced home deployments with three phase service (rare residential configurations or converted commercial buildings) and dedicated mechanical spaces can support S23 Hydro operation. For standard residential mining, the Antminer S21 XP 270TH air cooled on single phase 240V represents the practical ceiling. For operators wanting hydro cooling at home, the S21+ Hydro 395TH on universal single phase voltage offers a more feasible path.

Efficiency and form factor differentiation across the S23 lineup. S23 Air (318 TH/s at 11 J/TH): standard air cooled for conventional mining facility deployment. S23 Immersion (442 TH/s at 12 J/TH): immersion tank deployment for operators with immersion infrastructure. S23 Hydro 580TH (this product): compact hydro at 9.5 J/TH. S23 Hyd 3U (1.16 PH/s at 9.5 J/TH): high density hydro rack mount. S23E Hyd 2U (865 TH/s): higher tier hydro. The S23 Hydro 580TH leads on single unit efficiency for hydro deployments without specific 3U rack hardware, positioning between the S23 Immersion and S23 Hyd 3U on acquisition cost and deployment complexity.

100 kW industrial electrical panel supports approximately 18 S23 Hydro units producing 10.44 PH/s aggregate hashrate. Compare against alternatives at the same power budget: 100 kW of S21 XP Hydro 473TH (17 units producing 8.04 PH/s, 23 percent less aggregate hashrate), 100 kW of S21+ Hydro 395TH (17 units producing 6.72 PH/s, 36 percent less aggregate hashrate). Efficiency leadership compounds into meaningfully better aggregate output at the same power draw budget. For facilities constrained by electrical capacity rather than physical space, the S23 Hydro maximizes revenue potential.

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.

Industrial deployment with three phase power and hydro cooling infrastructure. Step one: install dedicated 380 to 415V three phase electrical service with 16 amp breakers minimum. Step two: install and commission external water cooling loop with pumps, plumbing, coolant fill, dry cooler or heat exchanger, inline filtration, and temperature monitoring. Verify inlet water temperature capability above 20°C across expected operating conditions. Step three: rack or shelf mount the S23 Hydro units and connect water inlet/outlet fittings to manifold system with individual isolation valves. Verify zero leaks before energizing. Step four: connect PSU power and Ethernet management cables. Step five: power on, allow coolant flow to stabilize for 2 to 3 minutes with inlet temperature above 20°C, find miner IP through DHCP, open Bitmain web interface, configure mining pool URL and Bitcoin wallet, verify hashrate reaches 565+ TH/s within 10 to 15 minutes.

Standard industrial hydro cooling maintenance with specific attention to temperature management. Weekly visual inspection of water fittings for leaks or corrosion. Monthly coolant quality testing (pH within spec, particulate levels minimal, glycol concentration if applicable). Every 12 to 24 months full coolant replacement depending on fluid chemistry and water quality. Quarterly pump and dry cooler inspection including flow rate verification and ambient temperature performance. Inline filter replacement when pressure differential exceeds specification. Hashboard failure rates on S23 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.
