MicroBT Whatsminer M73S PLUS 540TH

The M73S+ produces 540 TH/s of SHA-256 hashrate at 7,200W and 13.33 J/TH efficiency in the MillionMiner rated specification. Manufacturer headline specs per Blockspace Media and Hashrate Index document the broader binning range at 540 to 600 TH/s with 12.5 J/TH leading efficiency rating. Overclock mode scales to 10,000W for approximately 600 TH/s peak output. MicroBT rates the unit at plus or minus 3 percent hashrate tolerance. The 12.5 J/TH rating ties the M73S+ with the M76S+ immersion variant as the efficiency leaders across the entire M70 generation.

Hydro cooling uses closed loop water circulation through internal channels in a sealed 4U chassis. The M73S+ does not submerge in fluid. Water absorbs heat inside the chassis and carries it to an external cooling loop through standard plumbing. Units install in 19 inch server racks alongside other data center equipment. Immersion cooling submerges the entire miner in dielectric fluid held in specialized tanks. The M73S+ hydro approach uses off the shelf pumps, standard plumbing, and common water glycol coolant. Immersion requires specialized dielectric fluid at higher cost per liter, custom tank infrastructure, and more complex fluid quality management.

Connaissance et intégration de l'infrastructure. Les installations disposant déjà de serveurs informatiques refroidis par liquide en fonctionnement (centres de données, facilities de colocation, environnements IT d'entreprise) disposent d'une expertise et d'un équipement en refroidissement par eau. L'ajout d'unités M73S+ permet d'étendre l'infrastructure existante plutôt que de construire des systèmes de réservoir d'immersion dédiés. Les racks serveurs standard de 19 pouces et les conduites d'eau s'intègrent dans l'architecture des installations existantes. L'immersion a plus de sens pour des installations de minage dédiées construites spécifiquement autour de réservoirs, ou dans des opérations où l'avantage de densité de 19 unités M76S+ par panneau de 100 kW dépasse le coût de l'infrastructure sur mesure.

Three bins across the M73 rack mount hydro tier. M73 base: 470 TH/s at 14.5 J/TH. M73S mid: 500 TH/s at 13.5 J/TH. M73S+ top (this product): 540 to 600 TH/s at 12.5 J/TH. All three share the identical 4U chassis, 7,200W rated power envelope, 380 to 480V three phase requirements, and water cooling architecture. Chip binning grade differentiates them. The M73S+ delivers 15 percent more hashrate than the base M73 at 14 percent better efficiency, at the acquisition price premium that top bin silicon commands.

380 to 480V three phase commercial or industrial power. At 415V three phase: approximately 17 amps per phase in rated 7,200W mode, or 24 amps per phase in overclock 10,000W mode. At 480V three phase: approximately 15 amps in rated mode, 21 amps in overclock mode. Rated mode fits standard 20 amp commercial breakers. Overclock mode requires 32 amp breakers for reliable operation. Not suitable for standard residential or small commercial electrical systems. European, Middle Eastern, and industrial Asian facilities at 380 to 415V three phase have direct deployment paths.

Closed loop water circulation with off the shelf components. Required: circulation pumps sized for total fleet flow rate, standard plumbing fittings (no specialized immersion connectors), water glycol coolant mixture, external heat rejection through dry coolers or water to water heat exchangers, and inline filtration. Coolant volume scales roughly 2 to 4 liters per unit plus system reservoir capacity. Each M73S+ adds approximately 24,570 BTU per hour of thermal load. For rack scale deployment with multiple units, thermal rejection scales proportionally and uses standard data center cooling equipment available from any industrial supplier.

A standard 42U rack holds 10 M73S+ units (factoring space for cooling manifolds and cable management) producing 5.4 PH/s at 72 kW per rack. Compare against the M76S+ immersion option (19 units in tanks per 100 kW producing 7,410 TH/s) or M79S hydro 3U option (7 units per 100 kW producing 6,510 TH/s). The M73S+ rack mount approach wins on infrastructure familiarity and standard server rack integration. Immersion wins on aggregate hashrate per kilowatt of electrical capacity.

At MillionMiner's $0.08 per kWh onsite calculator: $17.64 daily revenue, $13.82 electricity, $3.81 net profit per day. At $0.07 per kWh industrial rates: approximately $12.10 daily electricity against similar revenue, netting $5 to $6 daily. At $0.04 per kWh negotiated industrial rates: $6.91 daily electricity, netting $10 to $11 daily profit per unit. At upper bin 600 TH/s output, daily revenue improves 11 percent over the 540 TH/s floor. Run overclock mode calculations against your electricity rate because the 2.8 kW additional draw must recover through proportional revenue gains.

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), and DigiByte (DGB SHA-256 chain). Merged mining BTC alongside BCH and BSV through supporting pools like ViaBTC and F2Pool adds marginal secondary revenue.

Industrial deployment with three phase power and water cooling infrastructure. Step one: install three phase 380 to 480V electrical service. Step two: install and commission water cooling loop including pumps, plumbing, dry coolers, and initial coolant fill. Step three: rack mount M73S+ units in standard 19 inch racks and connect water inlet/outlet fittings to your manifold system. Verify zero leaks before energizing. Step four: connect PSU power and Ethernet management. Step five: power on, allow coolant flow to stabilize, find each miner IP through DHCP, configure pool URL and Bitcoin wallet through the Whatsminer web interface, verify hashrate reaches 524+ TH/s within 15 to 20 minutes per unit.

Yes, with appropriate infrastructure provisioning. Overclock mode scales the M73S+ to 10,000W and approximately 600 TH/s output. Requirements for stable overclock operation: electrical circuits sized for 32 amp per phase draw rather than 20 amp, water cooling loop with additional thermal margin (25 to 30 percent above rated mode capacity), and electricity pricing that makes the additional draw economically worthwhile. The 2.8 kW additional power in overclock mode must generate proportional hashrate gains to justify the electricity cost. At $0.04 per kWh industrial rates, overclock typically wins daily margin. At $0.08 per kWh or above, rated mode often delivers better net profit.

Water cooling maintenance. Weekly visual inspection of all fittings for leaks or corrosion. Monthly coolant quality testing (pH within spec, particulate levels minimal). Every 12 to 24 months full coolant replacement depending on fluid chemistry. Quarterly pump and dry cooler inspection. Inline filter replacement when pressure differential exceeds specification. Hashboard failure rates on hydro units run lower than air cooled because chips operate at consistent temperatures. Water cooling maintenance is simpler than immersion fluid management because water glycol is cheaper and more widely available than dielectric fluid.

Any Stratum compatible Bitcoin pool. Foundry USA leads by network share. F2Pool has the longest operational track record and supports merged mining. AntPool remains popular across MicroBT fleets. ViaBTC offers accumulation mode payouts. For fleet deployments above 5 PH/s (equivalent to 10+ M73S+ units), direct negotiated agreements with major pools typically secure reduced fees below standard rates.

Different deployment scales. M73S+: 540 to 600 TH/s at 7,200 to 10,000W and 12.5 J/TH headline in 4U chassis. Antminer S23 Hyd 3U: 1,160 TH/s at 11,020W and 9.5 J/TH in 3U chassis. Bitmain's S23 Hyd 3U leads on absolute hashrate per unit and efficiency per terahash. The M73S+ fits facilities wanting hydro mining at mid power tier with broader bin flexibility. For operations building dedicated petahash class deployment, the S23 Hyd 3U is the more aggressive choice. For operations integrating hydro mining into existing data center infrastructure at comfortable per unit scale, the M73S+ fits better.

MicroBT's 360 day factory warranty on the complete machine covers 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, and operation outside the 5 to 45 degree Celsius range. Document coolant testing schedule and maintenance logs to protect warranty coverage.

Yes. MillionMiner operates managed hosting facilities with three phase industrial power and water cooling infrastructure capable of supporting M73S+ deployments. Hosted deployment eliminates facility infrastructure CapEx. Professional hosting at negotiated industrial rates often beats self hosting when full infrastructure costs are included.

Standard Whatsminer firmware provides the same web interface, pool configuration format, and management API as other MicroBT miners. Fleet management tools including Foreman, Awesome Miner, Hive OS, and Braiins OS+ discover M73S+ units automatically through network scanning. Additional monitoring metrics for hydro operation (coolant flow rate, inlet/outlet temperatures) appear in hydro specific dashboards. Mixed brand and cooling type fleets handle through unified dashboards.

Ajouts CapEx au-delà de l'acquisition d'un mineur : installation d'un service électrique triphasé (5 000 à 20 000 $ par installation), boucle de refroidissement à eau et pompes (5 000 à 20 000 $ par rack en fonction de la capacité), racks et câblage (1 500 à 4 000 $ par rack). OpEx annuel par unité à 7,2 kW nominal : électricité à 5 045 $ à 0,08 $ par kWh, 2 522 $ à 0,04 $ par kWh pour les tarifs industriels, maintenance du glycol refroidisseur d'eau (100 à 300 $ par unité par an), pièces de rechange et maintenance. Les coûts CapEx de l'infrastructure de refroidissement à eau sont sensiblement inférieurs à ceux des systèmes de réservoir d’immersion, ce qui constitue l'argument économique principal en faveur du refroidissement par rack hydro sur le déploiement par immersion.

No. The M73S+ requires 380 to 480V three phase industrial power unavailable in residential settings, water cooling loop infrastructure, and professional installation for both electrical service and plumbing. Home mining hardware caps at around 3,500W per unit on standard 240V 20A circuits. For high hashrate home deployment, the Antminer S21 XP at 270 TH/s represents the realistic ceiling. The M73S+ is strictly industrial hardware for professional mining facilities and data centers.

Within the M73 rack mount hydro tier: the Whatsminer M73S at 500 TH/s and M73 at 470 TH/s provide lower bin alternatives in the same chassis. Cross cooling at MicroBT: immersion variants M76 and M78 series cover alternative liquid cooling for facilities with tank infrastructure, M79 and M79S cover high power hydro tier (14 kW and 20 kW per unit). Cross brand hydro: the Bitmain Antminer S23 Hyd 3U at 1.16 PH/s provides vendor diversification at higher power tier. For algorithm diversification, the Antminer KS7 at 45 TH/s covers Kaspa mining. MillionMiner's ASIC hosting service accepts M73S+ units at negotiated industrial electricity rates.
