Antminer S21e Hyd – 288 TH/s

Product Description

The Antminer S21e Hyd is a hydro-cooled SHA-256 ASIC miner from Bitmain for Bitcoin (BTC). This 288 TH/s version is listed at 4,896 W, an efficiency of 17.00 J/TH.

As a hydro-cooled machine it moves heat out with liquid rather than fans, so it does not cool itself out of the box: it has to be connected to a liquid loop with a pump, piping and a dry cooler or heat exchanger. See our air vs hydro cooling guide.

Frequently asked questions

How much power does the Antminer S21e Hyd use?

This 288 TH/s version is rated at 4,896 W (4.9 kW) from a 380-415 V AC three-phase supply. A load this size is sized by an electrical engineer, not a household breaker.

Can I run the Antminer S21e Hyd at home?

Not in an ordinary home. It needs 380-415 V AC three-phase power and a liquid-cooling loop with a pump, piping and a dry cooler or heat exchanger; it does not cool itself out of the box. Plan it as a facility installation and read our guide to air vs hydro cooling.

How loud is the Antminer S21e Hyd?

It is listed at 50 dB. The fans are gone; the pumps and dry cooler of the loop set the real noise level.

What coins can the Antminer S21e Hyd mine?

It mines SHA-256, so it can mine Bitcoin (BTC) and other SHA-256 coins such as Bitcoin Cash (BCH). It works with any SHA-256 pool; see mining pools explained.
