ANTMINER S21 Hydro, SHA-256, super efficiency with a top hashrate! Enter a new era of liquid cooling!

Bitmain revealed Groundbreaking S21 Hydro at World Digital Mining Summit 2023

BITMAIN revealed its flagship Antminer S21 Hydro at the World Digital Mining Summit 2023. The summit, took place in Hong Kong from September 22nd to 23rd, carried the theme “Building up for the Bull Market, Mining at the Right Time.”

The S21 Hydro is the latest in Bitmain’s liquid series, achieving an efficiency of 16 J/TH. This marks a significant leap from previous models like the S19 XP Hydro at 20.8 J/TH .

BITMAIN ANTMINER S21 Hydro, SHA-256, superior performance with a top hashrate! The future is coming!

*Unlike most sellers we ship from the Netherlands (EU zone)
*Order without VAT (0%) with a EU company VAT number or by ordering from outside EU.
*The price of mining machines must be adjusted frequently according to many factors, including cryptocurrency/USD exchange rate, the network difficulty, expected difficulty increase, stock availabilty or changes in the algorithm. Refund requests based on these factors cannot be honored.
*Up to two years warranty instead of 180 days.
*Best price in the EU!

NOTE:

(1-1). The Hashrate value, Power on wall, and Power efficiency on wall are all typical values, The actual Hashrate value fluctuates by 3%, and the actual Power on wall and Power efficiency on wall fluctuate by 5%.
(1-2). Inlet water temperature.
(2-1). Caution: Wrong input voltage may probably cause server damaged.
(2-2). Three-phase AC input, 10 A per wire.
(2-3). NEM: Normal Energy Mode; HEM: High Energy Mode.
(2-4). If the water conductivity is ≥100 μs/cm, the fluid must be replaced. The water conductivity is less than 20 μs/cm when the system is running at the first time.
