MicroBT Whatsminer M70S PLUS 244TH

The M70S+ produces 244 TH/s of SHA-256 hashrate at 3,140W and 12.87 J/TH efficiency in the MillionMiner rated specification. Manufacturer headline specs per Blockspace Media, Apexto, and X ON Mining document the broader binning range at 244 to 280 TH/s with 12.5 J/TH leading efficiency rating. Upper bin output reaches approximately 3,500W in overclock configuration. MicroBT rates the unit at plus or minus 3 percent hashrate tolerance. The 12.5 J/TH rating ties the M70S+ with the M73S+ hydro and M76S+ immersion variants as the three efficiency co leaders across the entire M70 generation.

It achieves efficiency leadership on the simplest infrastructure. The M73S+ (12.5 J/TH) requires rack mount hydro with water cooling loops. The M76S+ (12.5 J/TH) requires dielectric fluid immersion tanks. The M70S+ reaches the same 12.5 J/TH headline rating through standard air cooling on 220 to 240V single phase power. No liquid infrastructure, no three phase service, no custom tanks. This makes the M70S+ the most accessible path to top tier efficiency in MicroBT's current lineup, opening the efficiency class to small commercial operations and dedicated residential setups that cannot justify liquid cooling or three phase electrical investment.

220 to 240V single phase commercial or residential power through a C19 power cable connection. At 240V: approximately 13 amps continuous draw at 3,140W rated mode, or 15 amps at 3,500W overclock mode. Fits within standard 20 amp circuits with headroom. Works on European Schuko outlets (230V), UK BS 1363 (230V with rated adapters), and most international 220 to 240V infrastructure. In North America: requires 240V NEMA 6 or NEMA L6 outlets, available in commercial settings and accessible through dedicated residential circuits. Does not require three phase power, step up transformers, or specialized electrical upgrades.

Yes, with appropriate infrastructure and noise tolerance. Requirements: dedicated 220 to 240V 20 amp circuit (available via NEMA 6 outlet installation in North America or standard outlets in most other regions), dedicated mining space separate from living areas due to 75 dB noise output, adequate ventilation to dissipate 3.1 to 3.5 kW continuous thermal load, acceptance of summer heat and electrical cost. Deploy in garages, basements with insulation, outbuildings, or dedicated mining rooms. Not suitable for living spaces, bedrooms, home offices, or shared environments without industrial grade sound insulation.

Close competitors at the efficiency frontier for single phase air cooled hardware. M70S+: 244 to 280 TH/s at 3,140 to 3,500W and 12.5 J/TH headline on 220 to 240V. Canaan Avalon A16XP: 12.8 J/TH on 220 to 277V, higher hashrate per unit but at slightly lower efficiency rating. The M70S+ wins on efficiency by a thin margin at a narrower voltage operating range. The A16XP wins on absolute hashrate per unit for operators wanting maximum output per chassis. Fleet deployment mixing both brands is viable for vendor diversification.

M70S+: 244 to 280 TH/s at 3,140 to 3,500W and 12.5 J/TH headline on 220 to 240V. Antminer S21 XP: 270 TH/s at 3,645W and 13.5 J/TH on 200 to 277V. The M70S+ leads on efficiency at 12.5 J/TH versus the S21 XP at 13.5 J/TH. The S21 XP leads on absolute hashrate per unit at 270 TH/s versus 244 TH/s rated at the M70S+ floor. At upper bin M70S+ output (280 TH/s) the gap closes and the M70S+ wins on both metrics. For operators optimizing efficiency at any given power draw, the M70S+ leads. For operators optimizing hashrate per unit at the base bin configuration, the S21 XP wins.

Three bins across the M70 standard voltage air cooled tier. M70 base: 214 to 236 TH/s at 14.5 J/TH and 3,140W. M70S mid: 226 to 258 TH/s at 13.5 J/TH and 3,140 to 3,500W. M70S+ top (this product): 244 to 280 TH/s at 12.5 J/TH and 3,140 to 3,500W. All three share the identical chassis, 220 to 240V single phase requirement, and Whatsminer firmware. Chip binning grade differentiates them. The M70S+ delivers 14 percent more hashrate than the base M70 at 14 percent better efficiency, at the acquisition price premium top bin commands.

Upper bin M70S+ output at 280 TH/s improves daily revenue by 15 percent over the 244 TH/s floor rate. Home deployments at $0.10 per kWh: approximately $0.44 daily profit per unit, typically net negative after accounting for hardware depreciation. Economic viability at scale requires industrial electricity below $0.07 per kWh.

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.

Residential or small commercial setup. Step one: verify 220 to 240V circuit with 20 amp capacity (install dedicated NEMA 6 outlet in North America if needed). Step two: ensure adequate ventilation in deployment space (exhaust fans, intake airflow, appropriate temperature management). Step three: connect PSU to outlet using the included C19 power cable. Step four: connect Ethernet cable to router or switch. Step five: power on, find miner IP through router DHCP client list or IP scanner tool, open web interface, configure pool URL and Bitcoin wallet, verify hashrate reaches 237+ TH/s within 10 to 15 minutes.

75 dB is standard industrial ASIC noise, comparable to a vacuum cleaner at close range. Not suitable for residential living spaces, bedrooms, home offices, or shared office environments. Appropriate deployment locations include dedicated mining rooms, garages with proper ventilation, basements with sound insulation, outbuildings or sheds, shipping container installations, warehouse mining operations, and professional hosting facilities. Sound insulation boxes marketed for ASIC deployment can reduce noise by 15 to 20 dB but require attention to thermal management.

Upper bin M70S+ output runs 244 to 280 TH/s at 3,140 to 3,500W per Apexto and X ON Mining specifications. Whether this represents factory configured overclock mode or upper bin silicon varies by batch. The 3,500W upper range draw requires 20 amp circuit capacity at 240V and adequate ventilation for the additional thermal load. Operators can run at the rated 3,140W mode for conservative 24/7 stability or push toward upper bin output when electricity pricing and cooling capacity support higher draw. Stock firmware provides limited tuning options.

Standard air cooled ASIC maintenance. Monthly fan cleaning with compressed air to clear dust buildup. Quarterly hashboard connector inspection. Semi annual firmware updates when MicroBT releases patches. Continuous ambient temperature monitoring to keep the unit within the 5 to 45 degree Celsius operating range. Every 18 to 24 months at full duty cycle, expect at least one fan replacement per unit due to bearing wear. Budget 3 to 5 percent of acquisition cost annually for replacement fans and parts.

Any Stratum compatible Bitcoin pool. Foundry USA leads by network share with competitive FPPS payouts. F2Pool has the longest operational track record and supports merged mining. AntPool remains popular across MicroBT fleets. ViaBTC offers accumulation mode payouts reducing daily variance. Solo mining through Solo CK Pool is feasible for operators accepting high variance, typical block rewards at 244 TH/s run monthly to quarterly on average at current network difficulty. For mid sized commercial fleets above 2.4 PH/s (equivalent to 10+ M70S+ units), negotiated pool fees below standard 1 to 2 percent are typically available.

A standard 100 amp subpanel at 240V supports approximately 7 M70S+ units at rated 3,140W producing 1,708 TH/s aggregate. A 200 amp commercial service supports approximately 14 M70S+ units producing 3,416 TH/s aggregate. For dedicated mining facilities with three phase to single phase branch circuits, larger deployments become practical. Compact 13.5 kg chassis allows shelf or rack placement optimizing unit count per physical area.

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 inadequate cooling or ventilation, operation outside the 5 to 45 degree Celsius range, power surge damage from inadequate electrical protection, physical mishandling, and unauthorized firmware modifications. MillionMiner routes warranty claims through direct MicroBT channels for faster resolution than secondary market purchases provide.

Yes. MillionMiner operates managed hosting facilities with 220 to 240V single phase service and ventilation infrastructure capable of supporting M70S+ deployments. Hosted deployment eliminates facility infrastructure CapEx for operators preferring turnkey air cooled deployment. Professional hosting at negotiated industrial rates often beats self hosting when full infrastructure costs are included, particularly for operators without access to industrial electricity rates below $0.06 per kWh. Contact MillionMiner sales through the Get a Quote button for hosting pricing, capacity availability, and deployment timelines.

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 M70S+ units automatically through network scanning. Mixed brand fleets (MicroBT alongside Bitmain, Bitdeer, or Canaan hardware) handle through unified dashboards with brand specific monitoring metrics where applicable.

Not directly. The 5 to 45 degree Celsius operating range and 5 to 95 percent humidity tolerance are rated for indoor use. Outdoor deployment requires weather protection through enclosures, sheds, or shipping container installations. Direct exposure to rain, snow, humidity swings, or temperature extremes voids warranty and typically causes premature hardware failure. Operators deploying in hot climates (Middle East, South Asia, equatorial regions) should provision cooled or ventilated enclosures rather than direct outdoor installation.

Within MicroBT's M70 standard voltage air cooled tier: the M70S at 226 TH/s and M70 at 214 TH/s provide mid bin and base bin alternatives in the same chassis for volume fleet buyers. Cross family at MicroBT: M72 and M72S cover the 4 kW industrial voltage air tier (380 to 480V three phase), M76 series covers the 5.2 kW immersion tier, M73 series covers rack mount hydro, M78 and M79 series cover higher power liquid cooling tiers. Cross brand single phase alternatives: the Canaan Avalon A16XP at 12.8 J/TH, Antminer S21 XP at 270 TH/s and 13.5 J/TH, Antminer S21+ at 235 TH/s provide vendor diversification. For algorithm diversification, the Antminer KS7 at 45 TH/s covers Kaspa mining on separate infrastructure.
