MicroBT Whatsminer M79 920TH

The M79 delivers 920 TH/s of SHA-256 hashrate at its rated operating mode and 14,500W wall draw. It is the standard tier of MicroBT's M70 hydro cooled lineup, sitting one level below the petahash class M79S flagship at 1,350 TH/s and 20,000W. Both models share the same 3U rack mount chassis and hydro cooling architecture, so the choice between them comes down to power envelope and per unit economics at your specific electricity rate rather than physical deployment differences.

The M79 draws 14,500W continuous at the wall and delivers 15.761 J/TH efficiency in the rated performance mode. That positions it below the M79S on both absolute hashrate and efficiency per terahash, but above most air cooled alternatives in the same power class. For operators scaling hydro infrastructure incrementally, the M79's lower 14.5 kW draw per unit is easier to accommodate than the M79S's 20 kW, which matters for facilities with fixed circuit capacity or CDU thermal budgets that would require upgrades to handle multiple flagship units.

Any SHA-256 algorithm cryptocurrency. Bitcoin (BTC) is the primary target because it has the largest market capitalization and deepest pool infrastructure. Bitcoin Cash (BCH), Bitcoin SV (BSV), and Fractal Bitcoin all use SHA-256 and accept hashrate from the M79 through standard Stratum protocol. For pure Bitcoin mining, connect to Foundry USA, F2Pool, AntPool, ViaBTC, or any other major SHA-256 pool via the Whatsminer web management interface.

MicroBT unveiled the M70 series at Bitcoin MENA 2025 in Abu Dhabi in December 2025. Founder and CEO Yang Zuoxing presented the lineup at the conference with a focus on efficiency as the defining factor for post halving mining profitability. The M70 family spans air cooled models (M70, M70S, M72 series), hydro cooled models (M73 series, M76 series, M79, M79S), and immersion cooled variants. The M79 sits in the standard hydro tier below the M79S flagship, targeting operators who want petahash class Bitcoin mining capability at a lower per unit power envelope.

The M79 is hydro cooled and requires a liquid cooling loop with pumps, cooling distribution units (CDUs), heat exchangers, and leak safe plumbing sized for the 14.5 kW continuous thermal output per unit. This is not plug and play hardware. Facilities already running Bitmain S23 Hydro, S21 Hydro, or earlier MicroBT hydro generations can typically integrate the M79 into existing infrastructure with appropriate flow and temperature management. New operators entering hydro mining need to budget for the full cooling infrastructure separately from hardware acquisition cost. MillionMiner can advise on compatible setups or offer hosting at facilities with existing hydro infrastructure ready for immediate deployment.

M79: 920 TH/s at 14,500W and 15.761 J/TH. M79S: 1,350 TH/s at 20,000W and 14.815 J/TH. The M79S produces 47 percent more hashrate per unit at 38 percent more power, with slightly better efficiency per terahash. Per unit economics favor the M79S at cheap industrial power where you want maximum hashrate density. The M79 makes more sense when circuit capacity or CDU thermal budget is constrained, when per unit acquisition cost matters more than maximum absolute output, or when you want to balance fleet risk across multiple power tiers. Both share the same chassis and deploy together in the same hydro cooling loops without modification.

Every M79 from MillionMiner ships brand new and factory sealed with manufacturer warranty included. MicroBT provides 12 month standard warranty on Whatsminer hardware covering manufacturing defects under normal operation. Warranty claims flow through MillionMiner's support channel for faster resolution than direct manufacturer routing. Warranty does not cover damage from improper electrical infrastructure, inadequate cooling, or operator misuse, so ensure your facility meets the three phase power and hydro cooling requirements before deployment.

Yes. MillionMiner ships DDP (Delivered Duty Paid), which means all customs clearance, import duties, value added tax, and import related fees are included in the purchase price. You pay one number at checkout and the M79 arrives at your facility without additional payments to customs agents or freight forwarders. This matters for international buyers because SHA-256 mining hardware often faces high import tariffs in specific jurisdictions, and handling customs independently can add days or weeks to delivery timelines. DDP shipping removes that friction entirely.

Yes. MillionMiner offers professional hosting at partner data centers with existing hydro cooling loops, three phase power infrastructure, and competitive industrial electricity rates. Hosting includes rack space, cooling, power, network connectivity, and remote management through a dashboard showing hashrate, temperature, and accepted shares in real time. Billing is transparent with monthly statements covering electricity and hosting fees. For operators who want hydro cooled Bitcoin mining without building out their own infrastructure, hosting is the fastest path from purchase to production revenue.
