About the Antminer S23e U2H

The Antminer S23e U2H brings Bitmain's current generation into a 2U hydro chassis built for dense racking. It runs at 865 TH/s on 8,650 W, which is 10.0 J/TH, and comes in a single factory version. No Antminer in our catalog delivers more hashrate per machine, and it is among the most efficient hydro SHA-256 machines in our catalog.

It needs three phase power at 380 to 415 V and draws about 207.6 kWh a day per unit, so the supply and the loop are best sized before the units arrive. The site provides the liquid cooling loop with manifold plumbing, a dry cooler or water source, plus power cords and a PDU. At about 50 dB the unit itself is quiet, and the operating range is 5 to 45 °C. Each unit measures 600 × 483 × 86 mm and weighs 42.0 kg.

Questions

What buyers ask about the Antminer S23e U2H

All questions

How much power does the Antminer S23e U2H use?

8,650 W at 865 TH/s, about 207.6 kWh a day.

How efficient is the Antminer S23e U2H?

10.0 J/TH: every terahash per second costs 10 watts. That puts it among the most efficient hydro cooled SHA-256 miners in our catalog.

Which coins can the Antminer S23e U2H mine?

Bitcoin (BTC) and other coins on the SHA-256 algorithm, through a mining pool of your choice.

What does a site need for the Antminer S23e U2H?

Supply at 380 to 415 V, three phase, a liquid cooling loop, a dry cooler or water source, manifold plumbing, and power cords with a PDU. The operating range is 5 to 45 °C.

How loud is the Antminer S23e U2H?

About 50 dB at the unit, because the heat leaves through the water loop rather than through fans. At the site you mostly hear the heat rejection outside, a dry cooler for example; our guide to site noise explains the options.

What warranty comes with the Antminer S23e U2H?

New units carry the manufacturer warranty. Keep the stock firmware while it runs: third party or modified firmware generally voids it.

Can I order a single unit?

Yes. New models ship from a single unit, DAP or DDP to your door; the sea freight terms apply from 100 units.

How fast can you deliver?

Air freight takes 5 to 10 days door to door, sea freight 4 to 8 weeks. The lead time for your quantity is on the quote, which you get within 24 hours on business days.

Hydro miners compared, and what the loop really costs

Water cooled machines hold the efficiency frontier and they are quiet enough to put near people. They also come with a construction project attached, and that is the part to price before the hardware.

The breakeven power price, and why we ask for yours first

Every machine has an electricity price above which it stops making money. Work that number out and most of the hardware decision answers itself.

Three phase power for a mining site, in plain terms

Most modern miners are three phase machines, and most new sites are wired for something else. This is the vocabulary you need before you talk to an electrician.
