Latest Generation Hardware
This is a newer generation of mining hardware using recent ASIC chip technology. Compare efficiency, hashrate, and power draw against older generations before choosing a deployment plan.
Lower J/TH means lower electricity cost per unit of hashrate. Compare efficiency alongside purchase cost, noise, voltage, firmware support, and current network difficulty.

Official version-10 hydro reference: Bitmain documents the Antminer S21 XP Hyd. at 473 TH/s, 5,676 W typical wall power at 35°C inlet coolant, and 12 J/TH. Actual hashrate is ±3%; wall power and efficiency are ±5%.
Three-phase electrical gate
The official input is 380–415 V AC three phase, 50–60 Hz, with 12 A maximum current. Do not transfer air-cooled S21 electrical assumptions.
Exact coolant-loop requirements
Bitmain specifies 20–50°C inlet coolant and states that the unit will not start below 20°C. Required flow is 8–10 L/min, pressure is no more than 3.5 bar, and the connector is DN10/OD10.
The manufacturer webpage gives a generic pH range, while the newer manual provides medium-specific boundaries: antifreeze 7–9, pure water 6.5–7.5, and deionized water 8.5–9.5. This reference uses the more specific manual table and exposes the document distinction.
Never energize the server dry. Validate circulation, heat rejection, fluid quality, filtration, leak detection, grounding, protection, and emergency isolation.
Physical and environmental reference
The server is 339 × 173 × 207 mm and 13.8 kg net. Packaged dimensions are 570 × 316 × 430 mm and gross weight is 15.7 kg. Network access is RJ45 Ethernet. Storage is −20–70°C and relative humidity is 10–90% non-condensing.
Exact-name boundary
S21 XP Hyd., S21 XP+ Hyd., S21e XP Hyd., S21 Hyd., and air-cooled S21 XP are separate identities. Do not transfer PSU, coolant, firmware, controller, or recovery assumptions.
Firmware, recovery, and repair
- Identify the exact label, version, controller, and installed firmware.
- Use only the exact current manufacturer support entry.
- For no boot, coolant alarms, leakage, corrosion, instability, or electrical and thermal symptoms, request Antminer diagnosis.
