MicroBT Whatsminer M79S 1.35PH

The M79S delivers 1,350 TH/s of SHA-256 hashrate at its rated operating mode. That is 1.35 PH/s from a single hydro cooled unit, placing it at petahash class output alongside Bitmain's Antminer S23 Hydro 3U (1,160 TH/s) as one of only two Bitcoin miners in the world currently reaching this tier. It is the flagship of MicroBT's M70 generation and replaces multiple older generation units (M50, M60 series) with a single high density chassis.

Rated mode draws 20,000W from the wall and delivers 14.815 J/TH efficiency. MicroBT also built a proprietary Low Power Mode into the M79S that runs at approximately 14,000W and improves efficiency to roughly 13.5 J/TH, sacrificing some peak hashrate for lower electricity cost per terahash mined. The mode switch is software controlled through the Whatsminer management interface, allowing operators to tune performance based on current electricity rates, thermal conditions, or Bitcoin profitability margins.

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 M79S through standard Stratum protocol. For pure Bitcoin mining, connect to Foundry USA, F2Pool, AntPool, ViaBTC, or any other major SHA-256 pool.

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, framing the launch around the slogan "Green Driven, Ecosystem Redefined" and arguing that efficiency has become more important than Bitcoin price speculation for long term mining profitability. The M79S was the headline product because it reaches petahash level output from a single unit, a milestone only Bitmain had previously matched.

The M79S is hydro cooled, meaning it requires a liquid cooling loop with pumps, cooling distribution units (CDUs), heat exchangers, and leak safe plumbing sized for the 20 kW continuous thermal output per unit. This is not a plug and play device. Facilities that already run Bitmain S23 Hydro, S21 Hydro, or earlier MicroBT hydro generations can typically integrate the M79S 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.

These are the only two petahash class Bitcoin miners currently available. The M79S delivers 1,350 TH/s at 20,000W and 14.815 J/TH. The Antminer S23 Hydro 3U delivers 1,160 TH/s at 11,000W and 9.5 J/TH. Bitmain produces less absolute hashrate per unit but significantly better efficiency, earning roughly $26.15 per day in Bitcoin at current prices. The M79S produces more hashrate per unit and higher gross daily Bitcoin revenue (around $30.70) but consumes substantially more electricity. At residential power rates Bitmain wins on daily profit after electricity. At cheap industrial power the gap narrows. Operators often deploy both to balance absolute hashrate and efficiency across their fleet.

Every M79S 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 M79S 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 yourself 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 that shows hashrate, temperature, and accepted shares in real time. Billing is transparent with monthly statements covering electricity cost and hosting fees. For operators who want petahash class Bitcoin mining without building their own hydro infrastructure, hosting is the fastest path from purchase to production.
