Antminer S21 XP

Description

Antminer S21 XP

Are you looking for a powerful and efficient Bitcoin miner designed for modern large-scale mining operations? The Antminer S21 XP from Bitmain is a next-generation air-cooled SHA-256 ASIC miner engineered to deliver high hashing performance with excellent energy efficiency.

The Antminer S21 XP operates on the SHA-256 algorithm, making it ideal for mining Bitcoin (BTC) as well as other SHA-256 cryptocurrencies such as Bitcoin Cash (BCH) and Bitcoin SV (BSV). This advanced miner delivers a maximum hashrate of about 270 TH/s while consuming approximately 3645W of power, resulting in an energy efficiency of around 13.5 J/TH.

Built with Bitmain’s advanced ASIC chip architecture, the S21 XP offers significantly improved efficiency compared to earlier mining generations. With 270 TH/s hashing power and roughly 3.6 kW power consumption, the miner provides strong computing performance while helping mining farms reduce electricity costs per terahash.

The Antminer S21 XP uses a high-performance air-cooling system with multiple fans to maintain stable operating temperatures during continuous mining workloads. The miner typically operates with a noise level around 75–76 dB and is designed for deployment in professional mining facilities or well-ventilated environments.

The unit supports 220–277V power input and connects through a standard RJ45 Ethernet interface for network communication and remote management. The miner measures approximately 449 × 219 × 293 mm and weighs about 18.7 kg, making it suitable for rack-based or large-scale mining farm installations.

With 270 TH/s SHA-256 hashing power, 3645W power consumption, and 13.5 J/TH efficiency, the Antminer S21 XP is one of the most efficient air-cooled Bitcoin miners available, offering strong performance and reliability for modern Bitcoin mining operations.
