Bitmain Antminer S21+ Hydro 358Th/s

Antminer S21+ Hydro 358Th/s is a next-generation hydro-cooled ASIC from Bitmain, introduced in February 2025. It utilizes the SHA-256 algorithm and demonstrates an impressive performance of up to 358 TH/s while consuming only 5500W of power. With an energy efficiency of 16 J/TH, it can confidently compete with other devices in this segment. Antminer S21+ Hydro is suitable for mining Bitcoin (BTC), Bitcoin Cash (BCH), Peercoin (PPC) and other SHA-256-based cryptocurrencies. The model is not equipped with classic fans – instead, it uses a liquid cooling system that provides minimal noise level (up to 50 dB) and makes it possible to integrate into heating solutions. The unit requires connection to a three-phase power supply system with a voltage of 380-415 V. The integrated power supply and standard Ethernet port allow easy integration of the miner into existing infrastructure. The S21+ Hydro 358Th/s weighs only 15 kg and has compact dimensions, which makes installation and maintenance as convenient as possible. Manufactured in China, the miner comes in new condition and is backed by Bitmain’s official 6-month warranty. In addition, ASICFOX provides its own 6-month warranty covering all warranty cases, taking into account the time required for possible shipment to the factory. This device is an excellent choice for those looking for a reliable, powerful and efficient solution for both home mining and industrial use. The Antminer S21+ Hydro is a reliable foundation for any mining farm, thanks to its combination of high yield and sophisticated cooling system.
