Overview
The Antminer S21+ Hydro is a hydro-cooled SHA-256 ASIC miner from Bitmain, built to mine Bitcoin (BTC). It delivers 395 TH/s at a power draw of 5,925 W, which works out to roughly 15 J/TH.
At 15 J/TH it is a strong efficiency level for current-generation Bitcoin mining. Lower J/TH means more hashrate for every kilowatt-hour, which matters most over the multi-year life of a miner.
As a hydro (water-cooled) unit it needs a liquid-cooling loop rather than fans, allowing high power density and stable chip temperatures. It is a natural fit for Qubite’s hosting in the UAE.
