Product Details

MicroBT Whatsminer M66 280TH Base Model Hydro Cooled SHA-256 Bitcoin Miner

Base bin of the M66 hydro series on universal voltage. 280 TH/s at 5,572W. The M66 family scales through M66S (298 TH/s), M66S+ (318 TH/s), and M66S++ (356 TH/s), all sharing the same chassis and water connections. The base M66 sits 76 TH/s below the top bin, the largest spread in the M66 product line.

Single phase hydro. 100 to 240V universal. This is the M60 generation entry point for water cooled Bitcoin mining without three phase infrastructure. Daily electricity at $0.07 per kWh: $9.36. Monthly: $281. Water cooled at 50 dB from external infrastructure.

The M66 base competes with the Bitmain S21 Hyd (335 TH/s, 5,360W, universal voltage). Bitmain produces 20 percent more hashrate at 4 percent less power. The MicroBT M66 wins only on pricing. If the M66 costs enough less per unit to offset lower output, the fleet volume math works.

Same chassis as all M66 bins. Mix and match based on distributor pricing. MicroBT Whatsminer firmware. 18 kg. 267 x 147 x 401mm. Ethernet. 5 to 40 degrees Celsius.

For fleet operators evaluating this model: total cost of ownership equals acquisition price plus electricity ($9.36 daily at $0.07 per kWh) over your planned deployment horizon. Compare against every alternative at similar Bitcoin hashrate. The model delivering more coins per dollar of total investment at your electricity rate is the correct purchase.

The WhatsMiner M66 at 5572W produces 280 TH/s of SHA 256 hashrate against a network exceeding 600 EH/s. newer SHA 256 ASICs from every manufacturer improve 20 to 40 percent per generation, compressing WhatsMiner M66 margins over time.

Whatsminer M66 280TH Base Hydro Cooled Bitcoin Miner

Base bin in MicroBT's M66 universal voltage hydro family. 280 TH/s at 5,572W on 100 to 240V single phase. Lowest cost entry to one of the few hydro Bitcoin miner families that runs on standard single phase power. 50 dB.
