MicroBT Whatsminer M73S 500TH

The M73S produces 500 TH/s of SHA-256 hashrate at 7,200W and 14.4 J/TH efficiency in the MillionMiner rated specification. Manufacturer headline specs per Apexto, Zeus Mining, and X ON Mining document the broader binning range at 500 to 540 TH/s with 13.5 J/TH efficiency. MicroBT rates the unit at plus or minus 3 percent hashrate tolerance. Real world output depends on batch binning, coolant temperature, and operating conditions.

Same 7,200W rated power draw across all three variants. Same 4U chassis, same water cooling architecture, same 380 to 480V three phase requirements. Hashrate and efficiency differences come from chip binning. M73 base: 470 to 500 TH/s at 14.5 J/TH. M73S mid (this product): 500 to 540 TH/s at 13.5 J/TH. M73S+ top: 540 to 600 TH/s at 12.5 J/TH. Mid bin delivers 6 to 8 percent more hashrate than base at roughly 7 percent better efficiency, at smaller price premium than top bin commands.

Acquisition cost to performance ratio. Mid bin silicon captures the largest volume of the natural chip production distribution, which typically translates to the best acquisition cost per TH/s in any product lineup. Top bin silicon commands the price premium that matches its 12.5 J/TH efficiency peak. If the per unit price gap between M73S and M73S+ is less than $400 at your supplier, the M73S+ typically wins on total lifetime economics at $0.06 per kWh industrial rates over 3 year deployments. At larger price gaps, the M73S value proposition strengthens. Run the math with your specific supplier pricing.

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 and custom tank infrastructure.

380 to 480V three phase commercial or industrial power. At 415V three phase: approximately 17 amps per phase at 7,200W continuous draw. At 480V three phase: approximately 15 amps per phase. Fits within standard 20 amp commercial breakers with headroom. Same three phase requirements as the entire M73 series and other MicroBT M70 hydro variants, so facilities designed for one M73 variant support all others without electrical modifications.

Closed loop water circulation with off the shelf components. Required: circulation pumps sized for total fleet flow rate, standard plumbing fittings, 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. Uses standard data center cooling equipment available from any industrial supplier.

A standard 42U rack holds 10 M73S units producing 5 PH/s at 72 kW per rack. The M73S+ rack produces 5.4 PH/s, the M73 rack 4.7 PH/s at the same 72 kW. Mix bins within racks based on acquisition cost optimization. Compare against immersion alternatives (M76S+ at 19 units per 100 kW producing 7,410 TH/s in tanks) or high power hydro alternatives (M79S at 7 units per 100 kW producing 6,510 TH/s in 3U chassis). The M73S rack mount approach wins on infrastructure familiarity and standard server rack integration rather than absolute density per kilowatt.

At MillionMiner's $0.08 per kWh onsite calculator: $16.33 daily revenue, $13.82 electricity, $2.51 net profit per day. At $0.07 per kWh industrial rates: approximately $12.10 daily electricity, netting $4 to $5 daily. At $0.04 per kWh negotiated industrial rates: $6.91 daily electricity, netting $9 to $10 daily profit per unit. Upper bin M73S output at 540 TH/s improves daily revenue by 8 percent over the 500 TH/s floor rate. A 10 unit M73S rack produces $90 to $100 daily net profit at $0.04 per kWh.

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 without reducing Bitcoin hashrate contribution.

Yes. All three M73 variants share identical 4U chassis geometry, identical water cooling connector design, identical power requirements, and identical Whatsminer firmware. Mix bins freely within racks based on acquisition cost optimization and fleet deployment strategy. Common pattern: majority M73S units for value, some M73S+ units in slots where efficiency matters most, some M73 base units where budget is tightest. Fleet management handles mixed bin deployments transparently.

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, and dry coolers. Step three: rack mount M73S units in standard 19 inch racks and connect water inlet/outlet fittings. 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 485+ TH/s within 15 to 20 minutes per unit.

Water cooling maintenance. Weekly visual inspection of 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.

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.

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. Contact MillionMiner sales through the Get a Quote button for hosting pricing, capacity availability, and deployment timelines.

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.

Different scales. M73S: 500 to 540 TH/s at 7,200W and 13.5 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.

CapEx additions beyond miner acquisition: three phase electrical service installation ($5,000 to $20,000 per facility), water cooling loop and pumps ($5,000 to $20,000 per rack depending on capacity), racks and cabling ($1,500 to $4,000 per rack). Annual OpEx per unit at 7.2 kW: electricity at $5,045 at $0.08 per kWh, $2,522 at $0.04 per kWh industrial rates, water glycol coolant maintenance ($100 to $300 per unit annually), spare parts. Water cooling infrastructure CapEx runs meaningfully lower than immersion tank systems, which is the primary economic argument for rack mount hydro over immersion deployment.

Within the M73 rack mount hydro tier: the Whatsminer M73S+ at 540 to 600 TH/s is the top bin upgrade path, and M73 at 470 to 500 TH/s is the base bin alternative for volume fleet buyers. 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. 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.
