Frequently Asked Questions about the Antminer S21 Pro (FAQ)

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).
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).
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.
The S21 Pro is specified at 15 J/TH, which is one of its main selling points.
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.
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.
Yes we will ship from our EU-warehouse to EU customers. However we can also ship to non EU customers directly from the factory.
