Frequently Asked Questions about the Antminer S21 Pro (FAQ)

Is the Antminer S21 Pro a SHA-256 miner?

Yes. The Antminer S21 Pro uses the SHA-256 algorithm and is intended for mining Bitcoin (BTC) and other SHA-256 cryptocurrencies such as Bitcoin Cash (BCH) and Bitcoin SV (BSV).

What hashrate does the Antminer S21 Pro have?

The Antminer S21 Pro delivers up to 245 TH/s on the SHA-256 algorithm. Actual hashrate can fluctuate by ±3% depending on ambient temperature, firmware settings, and network conditions. The miner is compatible with Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV).

How much power does the Antminer S21 Pro use?

The Antminer S21 Pro draws approximately 3675 W at the wall at 25°C, with a ±5% tolerance. Its efficiency is rated at 15 J/TH, meaning every terahash of hashrate consumes 15 joules per second. Required input voltage is 220 V.

What efficiency does the Antminer S21 Pro offer?

The S21 Pro is specified at 15 J/TH, which is one of its main selling points.

How does the Antminer S21 Pro compare to the Antminer S21?

The Antminer S21 Pro improves on the Antminer S21 in both hashrate and efficiency. Where the S21 delivers up to 200 TH/s at 17.5 J/TH, the S21 Pro reaches up to 245 TH/s at 15 J/TH. Buyers focused on long-term operating cost benefit from the S21 Pro's lower energy use per terahash. The S21 remains attractive for buyers on a tighter capex budget who still want a current-generation SHA-256 miner.

Does it include a power supply?

Yes. Every Antminer S21 Pro unit from Antminer Distribution Europe includes the PSU. The C20-P13 (Antwire) cable is also included. You will need to provide a local C19 power cord rated for at least 16 A to connect the miner to your wall socket.
