Overview
The Antminer S21j XP Hydro is a hydro-cooled SHA-256 ASIC miner from Bitmain, built to mine Bitcoin (BTC). It delivers 495 TH/s at a power draw of 5,940 W, which works out to roughly 12 J/TH.
At 12 J/TH it is among the most efficient Bitcoin miners currently available. 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.
