MicroBT Whatsminer M79S 1.35PH

1.35 PH/s (1,350 TH/s) peak SHA-256 hashrate at 20,000W and 14.81 J/TH efficiency in rated performance mode. Standard hashrate mode delivers 930-1040 TH/s at proportionally reduced power. Low Power Mode delivers approximately 1,037 TH/s at 14,000W and 13.5 J/TH. One of only two Bitcoin miners currently available delivering single unit petahash output. Released December 2025 at Bitcoin MENA 2025 in Abu Dhabi.

HYDRO cooled. MM's spec sheet lists "Cooling Type: Immersion" but this is an error. The M79S uses a closed loop hydro cooling system with direct mounted water cooling plates transferring heat from ASIC chips to circulating liquid. MM's own product title ("Whatsminer M79S Bitcoin Hydro Miner"), body copy, and every distributor worldwide confirm hydro cooling. Immersion cooling would submerge the entire hardware in dielectric fluid, which the M79S is not designed for. For immersion mining, see the Bitmain S21 XP Immersion (300 TH/s) or MicroBT's dedicated immersion variants in the M70 family.

The two petahash class Bitcoin miners. S23 Hyd 3U at 1,160 TH/s, 11,000W, 9.5 J/TH. M79S at 1,350 TH/s, 20,000W, 14.81 J/TH (this product). The M79S produces 16 percent more hashrate per unit. The S23 Hyd 3U is 56 percent more efficient and consumes 45 percent less electricity. Daily electricity at $0.08 per kWh: M79S at $38.40 versus S23 Hyd 3U at $21.12. The S23 Hyd saves approximately $17.28 daily in electricity while producing 85 percent of the M79S hashrate. Over one year: $6,308 in electricity savings per unit favoring the S23 Hyd. For most industrial operators at standard electricity rates, the S23 Hyd 3U's efficiency advantage makes it the stronger choice. The M79S wins when hashrate density per rack slot matters more than per terahash efficiency or when MicroBT firmware ecosystem consistency matters for existing Whatsminer fleets.

Three operating modes. Rated Mode: 1,350 TH/s at 20,000W, 14.81 J/TH. Maximum hashrate for abundant electricity and cooling capacity. Standard Mode: 930-1040 TH/s at reduced power, similar efficiency to rated mode. Default setting for typical continuous operation. Low Power Mode: approximately 1,037 TH/s at 14,000W, 13.5 J/TH. Trades peak hashrate for meaningful efficiency improvement. Ideal for managing peak electricity rate periods or thermal constraints. Operators switch between modes through the Whatsminer management web interface without firmware changes or downtime.

50 dB per MicroBT's official specification and MM's body copy. MM's spec sheet lists 75 dB but this is an error on the spec sheet that contradicts MM's body copy. Hydro cooling eliminates high speed fans that drive air cooled miner noise. 50 dB is comparable to a quiet office or normal conversation. For industrial mining facility deployment, the 50 dB figure is substantially quieter than typical air cooled petahash equivalents (which would require multiple air cooled units at 75+ dB each to match the M79S hashrate).

MicroBT's current generation of Bitcoin mining ASIC hardware, launched starting in 2024-2025. Air cooled tier includes the M70 (entry industrial) and M70S (mid size operations). Hydro cooled tier includes M73S, M76S, and M79S flagship. The M73S+ reaches 12.5 J/TH efficiency at up to 600 TH/s, the efficiency leader in the M70 family. Immersion cooled variants also exist for dielectric fluid deployment. Efficiency across the M70 generation spans 14.5 J/TH down to 12.5 J/TH. All M70 products share the Whatsminer management interface and firmware ecosystem for unified fleet management.

Yes, at industrial electricity rates. MillionMiner calculator at $0.08 per kWh: +$13.30 daily ($51.70 revenue minus $38.40 electricity). Monthly: +$399. At $0.07 per kWh: +$22.90 daily. At $0.04 per kWh industrial rate: +$32.50 daily (approximately $974 monthly, $11,700 annually). Oneminers estimates $30-$42 daily earnings at $0.04 per kWh with 16-22 month ROI. The M79S operates profitably primarily at electricity rates below $0.06 per kWh. At retail residential rates above $0.12 per kWh, margins compress to break even or negative. Built exclusively for industrial operators with negotiated power rates.

380 to 415V AC three phase power required. At 20,000W rated operation, draws approximately 48 amps at 415V or 52 amps at 380V sustained per phase. Industrial 3-phase connector required. Standard residential and small facility electrical systems cannot handle this continuous load. Installation requires industrial scale electrical infrastructure typical of professional mining facilities or enterprise data centers. No single phase support. No 110V or 240V single phase compatibility.

Industrial Bitcoin mining operators with 380-415V three phase power infrastructure, engineered hydro cooling loop capacity for 20 kW thermal dissipation per unit, negotiated electricity rates below $0.06 per kWh for meaningful profitability, and rack slot constraints where hashrate per chassis matters more than per terahash efficiency. The M79S is NOT for home miners (no residential power compatibility), small facility operators (infrastructure costs prohibitive for single unit deployment), or efficiency optimizers (the S23 Hyd 3U at 9.5 J/TH is materially more efficient).

585 x 368 x 133 mm in 3U rack mount form factor. Weight varies by source: MM lists 37 kg, Mining Now lists 26 kg. Actual weight should be verified with MillionMiner before rack engineering planning. 3U height enables efficient density in professional data center environments: 20 units per 60U rack with standard slot spacing, or higher density in custom mining racks.

Engineered hydro cooling loop with: Cooling Distribution Unit (CDU) or manifold, pumps rated for 20 kW continuous heat rejection, heat exchanger or dry cooler, plumbing compatible with data center hydro standards, leak safe fittings, and coolant (typically water with corrosion inhibitors). Most operators integrate the M79S into existing CDU infrastructure alongside Bitmain S23 Hyd or other high density hardware. New deployments require full hydro facility setup with professional engineering.

0 to 40 degrees Celsius per Oneminers documentation. MM lists 5 to 45 degrees Celsius. For hydro cooled deployment, inlet coolant temperature (typically 25-45°C) is more relevant than ambient air temperature. The M79S delivers rated hashrate across typical data center ambient ranges (18-30°C) when the hydro cooling loop is properly sized. At altitudes from 900m to 2000m, highest operating temperature decreases by 1°C for every 300m increase in altitude.

All SHA-256 proof of work cryptocurrencies. Bitcoin (BTC) primary. Bitcoin Cash (BCH), Bitcoin SV (BSV), eCash (XEC), Fractal Bitcoin (FB), Peercoin (PPC), Namecoin (NMC), and other SHA-256 chains. AuxPoW merged mining through compatible pools. Same coin compatibility as every Bitmain S21/S23 series miner and Canaan Avalon A16 series.

MicroBT (Whatsminer brand) is one of the two dominant Bitcoin mining ASIC manufacturers alongside Bitmain. Founded by Yang Zuoxing in 2016. Yang was previously a chip design engineer at Bitmain before founding MicroBT. The Whatsminer product line is the second largest Bitcoin mining hardware brand by shipment volume after Antminer. MicroBT chips are designed in-house. The M70 generation launched at Bitcoin MENA 2025 in December 2025 reflects MicroBT's continued competition with Bitmain's S23 series across air cooled, hydro cooled, and immersion cooled products.

360 day MicroBT manufacturer warranty per BT-Miners and CryptoMinerBros. MillionMiner's other product listing lists "12-month manufacturer warranty" which is equivalent. X-ON Mining references "1 year limited warranty." Standard industry warranty period. Covers manufacturing defects and hardware failures under normal operating conditions. Improper voltage input, hydro loop failures, or user repair attempts may void warranty per standard MicroBT terms.
