About the Antminer S21+ Hydro
The Antminer S21+ Hydro sits in the middle of Bitmain's S21 hydro range: more efficient than the S21 Hydro and the S21e Hydro, less efficient than the XP models. In this factory version it runs at 338 TH/s on 5,070 W, which is 15.0 J/TH; the 395, 358 and 319 TH/s versions keep that efficiency at 5,925, 5,370 and 4,785 W, so a site can size each unit to its loop and its supply.
It needs three phase power at 380 to 415 V and draws about 121.7 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 the unit itself is quiet, and the operating range is 5 to 45 °C. Each unit measures 339 × 173 × 207 mm and weighs 13.8 kg, the chassis of the S21e Hydro and the S21e XP Hydro.

Read before you buy the Antminer S21+ 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.
