Description
Whatsminer M70 — 220 TH/s / 3190W SHA-256 ASIC Miner
Manufacturer: MicroBT
Overview
The Whatsminer M70 is MicroBT’s latest-generation air-cooled SHA-256 ASIC miner, built for serious Bitcoin mining operations that need strong hashrate density without moving to hydro or immersion cooling. This 220 TH/s variant draws 3190W at the wall, landing at roughly 14.5 J/TH — a solid efficiency point for an air-cooled unit in this hashrate class. It’s a straightforward drop-in upgrade for operators running standard 220–240V mining farm infrastructure.
Key Selling Points
- 220 TH/s hashrate for competitive block-reward share on the Bitcoin network
- ~14.5 J/TH efficiency, keeping electricity cost per TH low for an air-cooled model
- Air-cooled dual-fan design — no hydro/immersion infrastructure required
- Ethernet connectivity with standard Whatsminer web GUI and API support
- Compatible with Bitcoin, Bitcoin Cash, and other SHA-256 coins
- Built for medium-to-large scale farms or expanding solo-mining setups
