MicroBT Whatsminer M79 920TH

The M79 produces 920 TH/s of SHA-256 hashrate at 14,500W wall draw and 15.761 J/TH efficiency in the rated operating mode. MicroBT rates the unit at plus or minus 3 percent hashrate tolerance, so real world output typically falls between 892 and 948 TH/s depending on batch and operating conditions. Some distributor specifications document an alternate 968 TH/s at 14.1 kW and 14.5 J/TH performance profile when facility conditions support the improved configuration.

Same chassis, different power envelope. M79: 920 TH/s at 14,500W and 15.761 J/TH. M79S: 1.35 PH/s peak at 20,000W and 14.815 J/TH. Both use the identical 585 x 368 x 133 mm 3U rack mount chassis and hydro cooling architecture, so they deploy in the same cooling loops without modification. The M79S produces 47 percent more hashrate at 38 percent more power, with slightly better efficiency. The M79's lower power envelope (14.5 kW versus 20 kW) makes it easier to deploy in facilities with existing circuit capacity limits or CDU thermal budgets. For incremental scaling, start with the M79. For maximum rack density, commit to the M79S.

The M79 is the standard tier hydro cooled model in MicroBT's M70 generation. The full lineup spans three cooling approaches. Air cooled: M70, M70S, M72 series for small to mid size operations without liquid cooling. Hydro cooled: M73 series, M76 series, M79 (this product), and M79S flagship for industrial farms with liquid cooling loops. Immersion cooled: dedicated variants for dielectric fluid tank facilities. Efficiency across the family ranges from 14.5 J/TH on the most efficient tier down through the M79 at 15.761 J/TH. The M73S+ leads the family on efficiency at 12.5 J/TH with 600 TH/s output.

380 to 480V three phase industrial commercial power with appropriate circuit protection for sustained 14,500W continuous draw. At 415V three phase the unit draws approximately 35 amps per phase. At 480V: approximately 30 amps per phase. Standard residential and small commercial electrical systems cannot handle this load. European, Middle Eastern, and industrial Asian facilities running 380 to 415V three phase service have the direct deployment path. North American operators need 480V three phase (common in commercial facilities) or step down transformers. PSU ships included but power cord must match your three phase outlet configuration.

Engineered liquid cooling loop sized for 14,500W sustained thermal rejection per unit. Required components: coolant distribution unit (CDU), plumbing with quick disconnect fittings, manifolds for multi unit rack deployment, external heat rejection (dry cooler or water to water heat exchanger), and ongoing coolant quality management. Compatible coolant media include deionized water, antifreeze mixtures, and specialized hydro cooling fluids. Each M79 adds approximately 49,500 BTU per hour of thermal load. Same cooling loop design supports both M79 and M79S units, so facilities running one model can deploy the other without infrastructure modification.

Depends on electricity rate. At MillionMiner's $0.08 per kWh onsite calculator: $30.11 daily revenue, $27.84 electricity, $2.27 net profit per day. Margins are tight at standard rates. At $0.07 per kWh: approximately $24.36 daily electricity against similar revenue, netting roughly $5 to $6 per day. At $0.04 per kWh industrial negotiated rates: daily electricity drops to $13.92, netting $15 to $16 daily profit per unit. Residential electricity above $0.10 per kWh makes the M79 unprofitable at current difficulty. This is industrial hardware strictly for operators with negotiated industrial power rates.

Yes, with full infrastructure compatibility. Both models share the same 585 x 368 x 133 mm 3U chassis, identical hydro cooling connector specifications, and the same Whatsminer management firmware. Deploy M79 and M79S units in the same cooling loop manifolds without modification. The only operational differences are per unit power draw (14.5 kW versus 20 kW) and hashrate output (920 TH/s versus 1.35 PH/s peak), which affect circuit sizing and hashrate calculations. Fleet management through standard Whatsminer firmware or third party platforms handles mixed model deployment transparently.

Any SHA-256 proof of work cryptocurrency. Bitcoin (BTC) is the primary target with the largest market and deepest pool infrastructure. 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. At the M79 hashrate class, pool fee negotiation with major operators becomes realistic for fleet deployments above 10 units.

No. The M79 requires 380 to 480V three phase industrial power (unavailable in standard residential or small commercial settings), engineered hydro cooling infrastructure (14.5 kW continuous thermal rejection per unit), and professional installation for both electrical service and liquid cooling loops. Home mining hardware caps at around 3,500W per unit running on standard 240V 20A circuits. For operators wanting high hashrate home deployment, the Antminer S21 XP at 270 TH/s represents the realistic ceiling. The M79 is strictly industrial hardware.

Any Stratum compatible Bitcoin pool. Foundry USA is the largest by network hashrate share with competitive FPPS payouts. F2Pool has the longest operational track record and supports merged mining. AntPool remains popular despite the MicroBT manufacturer difference. ViaBTC offers multi algorithm support and accumulation mode payouts reducing daily variance. For fleet deployments above 5 PH/s (equivalent to 5 to 6 M79 units), direct negotiated agreements with major pools typically secure reduced fees below standard 1 to 2 percent rates.

Industrial deployment with three phase power and hydro cooling infrastructure. Step one: install three phase 380 to 480V electrical service with appropriate PDU capacity. Step two: install and commission hydro cooling loop including CDU, plumbing, and dry cooler. Step three: rack mount M79 units and connect coolant 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 892+ TH/s within 15 to 20 minutes per unit.

Hydro maintenance adds operational overhead compared to air cooled hardware. Weekly visual inspection of fittings for leaks or corrosion. Monthly coolant quality testing (pH, conductivity, particulate levels). Every 6 to 12 months full coolant replacement depending on fluid chemistry and filtration. Quarterly pump and CDU inspection at facility level. Hashboard failure rates are lower on hydro units than air cooled because chips run at cooler junction temperatures, but coolant system maintenance is an ongoing requirement. Budget 2 to 4 percent of acquisition cost annually for maintenance and parts.

Dramatically better efficiency per terahash. The M79 at 15.761 J/TH beats the M50 series at 26 to 28 J/TH by roughly 40 to 45 percent. One M79 replaces approximately 7 to 8 Whatsminer M50S units (110 TH/s each) while consuming meaningfully less total power. For operators facing replacement cycles on older generation hardware, upgrading to M79 units delivers substantial electricity cost savings and reduces facility maintenance overhead through fewer machines handling higher aggregate hashrate.

Some distributor specifications document an alternate M79 performance profile at 968 TH/s, 14.1 kW, and 14.5 J/TH. This represents a higher performance configuration that runs roughly 5 percent more hashrate at slightly lower power for meaningfully better efficiency (14.5 versus 15.761 J/TH). Whether your specific unit supports this profile depends on batch and binning. Facility conditions (coolant temperature, electrical stability) affect which profile operates reliably on a given deployment. Check batch specifications at purchase and verify stable operation after deployment.

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. MillionMiner routes claims through direct MicroBT channels for faster resolution.
