MicroBT Whatsminer M76S PLUS 390TH

The M76S+ produces 390 TH/s of SHA-256 hashrate at 5,200W and 13.33 J/TH efficiency in the MillionMiner rated specification. Manufacturer headline specs per Apexto, X ON Mining, Jingle Mining, and Blockspace Media document the broader binning range at 390 to 440 TH/s with 12.5 J/TH leading efficiency rating. Jingle Mining specifies 416 TH/s as the documented median bin. MicroBT rates the unit at plus or minus 3 percent hashrate tolerance, so real world output varies with batch and operating conditions. The 12.5 J/TH rating makes the M76S+ the most efficient model across MicroBT's entire M70 generation.

Lowest power draw per unit translates to the highest unit count per electrical panel. A 100 kW panel supports 19 M76S+ units at 5.2 kW each, producing 7,410 TH/s aggregate hashrate. The same 100 kW panel supports 14 M78S units at 7 kW each (6,608 TH/s aggregate), or 7 M79S hydro units at 14 kW each (6,510 TH/s aggregate). The M76S+ fleet delivers 12 to 14 percent more total hashrate from identical electrical capacity. For facilities where electrical capacity is the binding constraint rather than unit count, the M76S+ wins.

When electrical capacity is fixed and hashrate per kilowatt is the optimization target. Common scenarios: utility contracts capping power delivery (common in emerging mining markets), colocation facilities with transformer capacity limits, expansion zones without available grid capacity, mining sites powered by renewable sources with inherent capacity ceilings, and facilities where adding more electrical infrastructure is impractical or impossible. When power is unlimited but rack space is constrained, higher power tier hardware (M78S or M79S) with fewer units typically wins. The M76S+ optimizes for the specific constraint of fixed electrical allocation.

Same 5.2 kW power draw across all three models. M76 base: 336 to 374 TH/s at 14.5 J/TH. M76S: 362 to 406 TH/s at 13.5 J/TH. M76S+: 390 to 440 TH/s at 12.5 J/TH. The + variant leads on both hashrate and efficiency across the identical power envelope. For operators deploying any M76 series unit, the M76S+ delivers 16 percent more hashrate than the base M76 at 14 percent better efficiency from the same power. The price premium typically recovers quickly at any electricity rate above $0.04 per kWh through higher daily revenue and lower daily electricity cost per terahash.

380 to 480V three phase commercial or industrial power. At 415V three phase: approximately 13 amps per phase at 5,200W continuous draw, fitting well within standard 20 amp commercial breakers with headroom. At 480V three phase: approximately 11 amps per phase. Lowest per phase draw across the M70 immersion family, which simplifies electrical provisioning for facilities where each circuit supports multiple units. Same three phase requirements as the entire M70 immersion family, so facilities designed for M78 or M78S units support M76S+ without electrical modifications.

Dielectric fluid immersion tanks sized for the miner count plus thermal margin. Each M76S+ unit adds approximately 17,740 BTU per hour of thermal load, roughly 26 percent less than the M78 series (23,900 BTU/hr) and 64 percent less than the M79 series (49,500 BTU/hr). Smaller heat exchanger and pump capacity per unit. Shares tank compatibility with the M76, M76S, M78, M78S across the immersion family. Compatible dielectric fluids include single phase mineral oils, synthetic esters, and engineered two phase fluids. Typical fluid volume runs 40 to 60 liters per unit depending on tank geometry.

At MillionMiner's $0.08 per kWh onsite calculator: $12.77 daily revenue, $9.98 electricity, $2.78 net profit per day. At $0.07 per kWh industrial rates: approximately $8.74 daily electricity against similar revenue, netting $4 to $5 daily. At $0.04 per kWh negotiated industrial rates: $4.99 daily electricity, netting $7 to $8 daily profit per unit. A 19 unit M76S+ fleet deployed on a 100 kW panel produces approximately $140 to $160 daily net profit at $0.04 per kWh electricity, beating smaller unit count fleets from higher power tiers.

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 M76 and M78 series units share identical 267 x 147 x 401 mm chassis geometry, identical immersion tank connector design, identical power requirements, and identical Whatsminer firmware. Mix units freely across tanks based on per unit economics and fleet strategy. Common deployment: majority M76S+ units for density plus some M78S units where tank slot count exceeds immediate electrical capacity. Fleet management through standard Whatsminer firmware handles mixed model deployment transparently.

Industrial deployment with three phase power and immersion infrastructure. Step one: install three phase 380 to 480V electrical service. Step two: install and commission immersion cooling infrastructure including tanks, heat exchangers, pumps, and fluid. Step three: submerge M76S+ units in immersion tank slots. Step four: connect PSU power and Ethernet management. Step five: power on, allow fluid circulation to stabilize, find each miner IP through DHCP, configure pool URL and Bitcoin wallet through the Whatsminer web interface, verify hashrate reaches 378+ TH/s within 15 to 20 minutes per unit.

Immersion maintenance overhead. Monthly fluid quality testing (viscosity, dielectric strength, particulate content). Quarterly fluid filter inspection and replacement. Every 18 to 36 months full fluid replacement depending on fluid type. Heat exchanger cleaning every 6 to 12 months. Hashboard failure rates on immersion hardware run lower than air cooled because chips operate at consistent temperatures. More units per fleet means more individual maintenance cycles, which is the tradeoff of higher density deployment. Budget 3 to 5 percent of acquisition cost annually per unit for fluid replacement, filtration media, and spare parts.

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 3.9 PH/s (equivalent to 10+ M76S+ units), direct negotiated agreements with major pools typically secure reduced fees below standard rates.

Density versus unit count tradeoff. M76S+ at 5.2 kW per unit: 19 units per 100 kW producing 7,410 TH/s. M78S at 7 kW per unit: 14 units per 100 kW producing 6,608 TH/s. M76S+ delivers 12 percent more aggregate hashrate per kilowatt of electrical capacity at identical efficiency class (12.5 J/TH versus 13.88 to 14.83 J/TH). Tradeoff: 5 more units to install and maintain. For operators with unlimited electrical capacity but constrained rack or tank slot space, the M78S requires fewer physical units. For operators with fixed electrical capacity, the M76S+ extracts more output.

Some M76S+ binning runs toward the 440 TH/s upper range per Apexto and Jingle Mining specifications. Whether this represents factory overclock mode or upper bin silicon varies by batch. Stock firmware provides limited tuning options. Aggressive overclocking voids warranty and accelerates hardware degradation. Most operators run rated specifications for reliability, accepting the natural binning variation as the practical output range.

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 fluid quality neglect, contamination from improper immersion handling, physical damage during tank maintenance, power surge damage from inadequate electrical protection, and operation outside the 5 to 45 degree Celsius range. Document fluid quality testing schedule and maintenance logs to protect warranty coverage. MillionMiner routes claims through direct MicroBT channels.

Bitmain does not currently ship a direct immersion equivalent at the M76S+ efficiency class. Closest Bitmain alternatives include Antminer S21+ Immersion variants running lower hashrate per unit at 5.8 kW. For operators standardizing on immersion cooling and prioritizing efficiency, the M76S+ at 12.5 J/TH leads the market category. MicroBT currently holds the stronger immersion product portfolio for facilities committed to dielectric fluid infrastructure.

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 M76S+ units automatically through network scanning. Additional immersion specific monitoring metrics (fluid temperature, pump flow rate) appear in supported dashboards. Mixed brand and cooling type fleets handle through unified dashboards.

Acquisition cost per unit plus infrastructure and operations. CapEx additions at fleet scale: three phase electrical service, immersion tanks ($8,000 to $25,000 per rack depending on capacity), fluid fills ($1,500 to $4,500 per tank), heat exchanger and pump systems, racks and cabling. Annual OpEx per unit at 5.2 kW: electricity at $3,650 at $0.08 per kWh or $1,825 at $0.04 per kWh, fluid maintenance ($150 to $500 per unit annually), spare parts. The higher unit count compared to M79S deployments increases management overhead but reduces per unit thermal load and simplifies fluid infrastructure sizing.
