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.

Questions about this item

What is the typical power efficiency of the Antminer S21++ 225T and how much power does it draw at the wall?

The unit delivers a typical power efficiency of 16.5 J/TH while drawing 3712 W at the wall under standard conditions.

How loud is the miner when its fans run at maximum RPM during continuous operation?

The noise level reaches 76 dBA at 30 °C ambient when the fans spin at their highest speed.

What input voltage range must the site already provide for the included power supply to operate?

The power supply requires a single-phase 220~277 V AC source at 50~60 Hz with a maximum input current of 20 A.
