Antminer S21+Plus Description
The Bitmain Antminer S21+Plus, also known as the Antminer S21+, is an industrial air-cooled ASIC miner designed for the SHA-256 algorithm. It can be used to mine Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin SV (BSV), Fractal Bitcoin (FB), Namecoin (NMC), and other compatible SHA-256 cryptocurrencies.
Available hashrate options may include 216 TH/s, 225 TH/s, and 235 TH/s, depending on current stock and batch availability. The 216 TH/s configuration operates at approximately 3,564W with an energy efficiency of approximately 16.5 J/TH.
The S21+Plus is designed for professional mining farms, hosting facilities, warehouses, data centers, and other locations equipped with suitable electrical, ventilation, and heat-removal infrastructure. It requires a stable 220–277V single-phase electrical supply, proper grounding, sufficient circuit capacity, and a reliable Ethernet connection.
Antminer S21+Plus vs Antminer S21 and S21 Pro
The S21+Plus provides higher available hashrate and improved efficiency compared with the original S21. The S21 Pro generally provides better energy efficiency, while the S21+Plus may offer a more attractive balance between hardware price, hashrate, and availability.
