Product Details

MicroBT Whatsminer M66S Plus 318TH Hydro Cooled SHA-256 Bitcoin Mining Machine

Single phase hydro Bitcoin mining is a closing window across the industry, and the M66S+ is one of the machines keeping it open. 318 TH/s water cooled on standard 100 to 240V power. No three phase upgrade needed. No $10,000 to $50,000 electrical infrastructure investment.

MicroBT built the entire M66 hydro family on universal voltage: the base M66 at 280 TH/s, this M66S+ at 318 TH/s, and the top bin M66S++ at 356 TH/s. Same 267 x 147 x 401mm chassis, same water connections, completely interchangeable in the same rack and cooling loop. Buy whichever bin your distributor prices most aggressively and mix freely.

Why does this matter? Because MicroBT's newer M73 hydro series already moved to 380V+ three phase. Bitmain's S23 Hyd requires 380V+. Once M66 inventory depletes, the option to run MicroBT water cooled Bitcoin mining on single phase power may simply disappear from the market.

50 dB from the water cooling system. No internal fans. 18 kg compact enough for single person handling. Water or water glycol closed loop with standard plumbing. Each unit adds roughly 5.4 kW to your cooling load. MicroBT Whatsminer firmware for pool configuration and fleet management. 5 to 40 degrees Celsius operating range.

Daily electricity at $0.07 per kWh runs about $9.08. Monthly roughly $272. Factor that against Bitcoin revenue at 318 TH/s and current difficulty. The M66S+ competes not just on hashrate but on the infrastructure savings of avoiding three phase power entirely.

Whatsminer M66S+ 318TH Mid Tier Hydro Bitcoin Miner

MicroBT M66S+ mid bin. 318 TH/s hydro at 5,406W on universal 100 to 240V. Between the M66 (280 TH/s) and M66S++ (356 TH/s). Same chassis and cooling across all bins.

Universal voltage hydro is the key feature. M73 series and Bitmain S23 Hyd both need 380V+. The M66 series may be the last MicroBT hydro on single phase. Three phase upgrades cost $10,000 to $50,000+. This avoids that.

50 dB at 18 kg. 267 x 147 x 401mm. MicroBT firmware. Closing inventory window on universal voltage hydro from MicroBT. Ethernet. 5 to 40 degrees. Bitcoin, Bitcoin Cash, all SHA 256.

Moderate 50 dB operation. Runs in a dedicated home room, office, or basement without specialized noise isolation. Not bedroom quiet but manageable with a closed door. The middle ground between silent home and industrial noise.

MicroBT firmware provides pool configuration, hashrate monitoring, and operational alerts. Evaluate pricing against competing models at this hashrate tier for best fleet value.
