MicroBT Whatsminer M76 336TH

The M76 produces 336 TH/s of SHA-256 hashrate at 5,200W and 15.48 J/TH efficiency in the MillionMiner rated specification. Manufacturer headline specs per Apexto, Zeus Mining, and Blockspace Media document the broader binning range at 336 to 374 TH/s and 14.5 J/TH efficiency. MicroBT rates the unit at plus or minus 3 percent hashrate tolerance. Real world output depends on batch binning, fluid temperature, and operating conditions.

Same 5,200W power draw across all three variants. Hashrate and efficiency differences come from chip binning. M76 base (this product): 336 to 374 TH/s at 14.5 J/TH. M76S mid: 362 to 406 TH/s at 13.5 J/TH. M76S+ top: 390 to 440 TH/s at 12.5 J/TH. The M76 trades 14 percent hashrate versus the M76S+ for correspondingly lower acquisition cost. For operators whose binding constraint is hardware budget rather than operating efficiency, the M76 puts more units in the tank per dollar of capital spent.

Three scenarios favor the M76. First: hardware budget is the binding constraint rather than electricity cost, common in early stage facility buildouts where capital is scarce. Second: deployment horizon is short enough (under 2 years) that acquisition cost savings outweigh lifetime efficiency penalty. Third: electricity rate is cheap enough (below $0.04 per kWh) that the daily efficiency gap between bins is small in absolute dollar terms. If none of these apply, higher bin options typically win on total lifetime fleet economics.

Chip binning sorts manufactured silicon by tested performance. MicroBT fabricates wafers containing thousands of chips and tests each individually after manufacturing. Chips above the highest performance threshold qualify for M76S+ top bin. Chips above a mid threshold become M76S mid bin. Remaining functional chips become M76 base bin. All three tiers use physically identical silicon from the same production run. No difference in manufacturing quality, durability, or structural design between tiers. The M76 captures chips that tested below the top and mid thresholds but still within functional specifications. Lower clock speeds at base grade can actually reduce per chip thermal stress over extended operation.

No. Base bin chips are not inferior manufacturing. They come from the same silicon wafers, same production line, and same chip design as top bin. The only difference is tested performance grade during post fabrication quality sorting. Base bin chips may actually last longer than top bin under extended deployment because lower clock frequencies reduce thermal stress per chip. For multi year deployments where hardware longevity matters alongside acquisition cost, some fleet operators deliberately choose base bin silicon for the potential longevity advantage.

380 to 480V three phase commercial or industrial power. At 415V three phase: approximately 13 amps per phase at 5,200W continuous draw. At 480V three phase: approximately 11 amps per phase. Fits within standard 20 amp commercial breakers with headroom. Same three phase requirements as the entire M70 immersion family.

Dielectric fluid immersion tanks sized for the miner count plus thermal margin. Each M76 unit adds approximately 17,740 BTU per hour of thermal load. Shares tank compatibility with M76S, M76S+, M78, and M78S across the immersion family. Compatible dielectric fluids include single phase mineral oils, synthetic esters, and engineered two phase fluids.

At MillionMiner's $0.08 per kWh onsite calculator: $11.00 daily revenue, $9.98 electricity, $1.02 net profit per day. Tight margins at standard rates. At $0.07 per kWh industrial rates: approximately $8.74 daily electricity against similar revenue. At $0.04 per kWh negotiated industrial rates: $4.99 daily electricity, netting $5 to $6 daily profit per unit. A 19 unit M76 fleet on 100 kW panel produces approximately $95 to $115 daily net profit at $0.04 per kWh. Economic viability requires industrial electricity below $0.05 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.

Run the acquisition cost versus daily electricity savings math with your specific supplier pricing. Model the per unit price gap between bins against the daily efficiency savings at your electricity rate across your expected deployment horizon. If the per unit price gap between M76 and M76S+ is less than $330, upgrading to top bin typically wins at $0.06 per kWh industrial rates over 3 year deployments. At smaller price gaps, higher bins always win. At larger gaps, the M76 strengthens. Alternatively, mix bins within the same fleet: majority M76 for capital efficiency, some M76S+ units where efficiency matters most.

Yes. All three M76 variants share identical chassis, power requirements, tank compatibility, and Whatsminer firmware. Mix bins freely across tanks based on fleet deployment strategy. Common pattern: majority M76 units for capital efficiency with some higher bin units in specific slots. Fleet management handles mixed bin deployments transparently through unified Whatsminer firmware dashboards.

A 100 kW electrical panel supports 19 M76 units producing 6,384 TH/s aggregate hashrate. Alternative panel sizes scale linearly: 50 kW supports 9 units at 3,024 TH/s, 200 kW supports 38 units at 12,768 TH/s. The 5.2 kW tier maintains its density advantage over higher power tiers. Compared against 14 M78S units at 6,608 TH/s from 100 kW or 7 M79S hydro units at 6,510 TH/s, even the M76 base bin delivers comparable aggregate hashrate from identical electrical capacity.

Industrial deployment with three phase power and immersion infrastructure. Step one: install three phase 380 to 480V electrical service. Step two: install and commission immersion cooling infrastructure. Step three: submerge M76 units in immersion tank slots. Step four: connect PSU power and Ethernet management. Step five: power on, allow fluid circulation to stabilize, find each miner IP through DHCP, configure pool URL and Bitcoin wallet through the Whatsminer web interface, verify hashrate reaches 326+ TH/s within 15 to 20 minutes per unit.

Immersion maintenance overhead. Monthly fluid quality testing, quarterly filter inspection, every 18 to 36 months full fluid replacement, heat exchanger cleaning every 6 to 12 months. Higher unit count per fleet increases cumulative maintenance cycles but lower per unit thermal load reduces individual unit stress. Budget 3 to 5 percent of acquisition cost annually per unit for fluid replacement, filtration media, and spare parts.

Any Stratum compatible Bitcoin pool. Foundry USA leads by network share. 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. For fleet deployments above 3.4 PH/s (equivalent to 10+ M76 units), direct negotiated agreements with major pools typically secure reduced fees below standard rates.

No. The M76 requires 380 to 480V three phase industrial power unavailable in residential settings, dielectric fluid immersion tanks with fluid management infrastructure, and professional installation for both electrical service and fluid systems. Home mining hardware caps at around 3,500W per unit on standard 240V 20A circuits. For high hashrate home deployment, the Antminer S21 XP at 270 TH/s represents the realistic ceiling.

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 fluid quality neglect, contamination from improper immersion handling, physical damage during tank maintenance, power surge damage, and operation outside the 5 to 45 degree Celsius range. Warranty coverage is identical across all M76 bin variants.

Yes. MillionMiner operates managed hosting facilities with immersion cooling infrastructure capable of supporting M76 deployments. Hosted deployment eliminates facility infrastructure CapEx. Professional hosting at negotiated industrial rates often beats self hosting when full infrastructure costs are included.

Generally no, and potentially positively. Base bin chips run at lower clock frequencies than top bin silicon, which reduces per chip thermal stress over extended operational life. Some fleet operators deliberately choose base bin for multi year deployments where hardware longevity matters alongside peak efficiency. Counterargument: all M76 variants use identical silicon from the same production run, so base hardware durability differences are typically marginal. In practice, reliability differences between bins are small compared to reliability differences between cooling approaches (hydro versus immersion versus air).

Within the 5.2 kW immersion tier: the Whatsminer M76S at 362 to 406 TH/s is the mid bin upgrade path, and M76S+ at 390 to 440 TH/s is the top bin option for operators prioritizing efficiency. Cross tier at MicroBT: the M78 at 440 TH/s and M78S at 472 TH/s cover the 7 kW immersion tier for higher per unit hashrate. Hydro variants M73, M76 hydro, M79, M79S provide alternative liquid cooling approach. Cross brand options: the Antminer S21+ Immersion variants provide vendor diversification. For algorithm diversification, the Antminer KS7 at 45 TH/s covers Kaspa mining on separate infrastructure. MillionMiner's ASIC hosting service accepts M76 units at negotiated industrial electricity rates.
