Is the WhatsMiner M73S+ profitable?

The MicroBT WhatsMiner M73S+ mines Bitcoin on the SHA-256 algorithm at 540 TH/s, drawing 7,200 W (13.3 J/TH). At $0.08 per kWh it earns about $20.28 a day, spends $13.82 of that on power, and keeps $6.46. That’s around $194 a month. It stops making money above roughly $0.117 per kWh.

That puts it #34 of 522 on daily profit across every miner we track, and #25 of 262 SHA-256 miners on efficiency. It isn’t in stock with us at the moment. It’s a hydro (water-cooled) unit, released in December 2025.
