About the Antminer S21e XP Hydro
The Antminer S21e XP Hydro is a hydro miner of Bitmain's S21 generation, made to fill out an existing loop without adding infrastructure. This version is a 3U chassis with two machines in one rack unit, at 860 TH/s on 11,180 W, which is 13.0 J/TH; a single machine runs at 430 TH/s on 5,590 W. Against the S21+ Hydro, in the same chassis, a single machine delivers more hashrate at better efficiency; the S21 XP Hydro and the S21 XP+ Hydro, in the larger chassis of the S23 Hydro, are more efficient still.
It needs three phase power at 380 to 415 V and draws about 268.3 kWh a day per unit. 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 it is far quieter than air cooled machines, and the operating range is 5 to 45 °C; each unit measures 900 × 483 × 130 mm and weighs 42.7 kg.

Read before you buy the Antminer S21e XP Hydro
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.
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.
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.
