Purpose-built SHA256 ASIC miner
The Antminer S21++ 225T is a dedicated SHA256 ASIC miner engineered for Bitcoin, Bitcoin Cash and Bitcoin SV networks. It delivers a typical hashrate of 225 Th/s with a power efficiency of 16.5 J/TH at the wall. The unit includes an integrated power supply and operates on 220–277 V AC single-phase input.
Suited for hosted or industrial sites.
This hardware suits operators with access to 220–277 V infrastructure, adequate cooling for 3 712 W heat output and tolerance for 76 dBA noise at 30 °C ambient. It is not appropriate for residential circuits, noise-sensitive environments or altitudes above 2 000 m where the maximum operating temperature derates.
Deciding spec: 16.5 J/TH wall efficiency
The single figure that determines whether this miner fits an operation is the 16.5 J/TH power efficiency at 25 °C. At a typical 3 712 W draw, that efficiency dictates daily electricity cost and break-even threshold; if the local power rate makes this metric unprofitable, a different device must be chosen.
