Overview
Bitmain Antminer S21 Plus Hydro (358TH/s) — Hardware Overview
Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.
The Bitmain Antminer S21 XP+ Hydro (358 TH/s) presents itself as a deliberately engineered SHA‑256 workhorse: 358 terahashes per second delivered at a… nominal consumption of 5,370 watts, which equates to an energy efficiency of 15 watts per terahash (15 J/TH), a metric that straightforwardly informs capacity planning and cost models for Bitcoin, Bitcoin Cash and Bitcoin SV mining; its OD10 hydro‑cooling subsystem is the defining operational feature, enabling substantially lower die temperatures, reduced thermal cycling and therefore extended component lifetime, but it also imposes facility requirements - closed‑loop coolant management, water treatment and heat‑rejection interfaces, pump redundancy, leak detection and scheduled maintenance windows - that must be specified and contracted with the same rigor as electrical distribution and power‑quality measures; compact dimensions (410 x 170 x 209 mm) and an Ethernet interface simplify physical and network integration into high‑density racks, while the manufacturer’s stated environmental envelope (operating temperature roughly 5–45°C and relative humidity 5–95%) should be interpreted conservatively in practice, with operators preferring narrower, controlled conditions to avoid condensation and maintain long‑term reliability; at an acoustical level the unit is unusually quiet for its class (around 50 dB), enabling closer placement to monitored infrastructure, and its combination of high hash rate and repeatable energy performance makes it a competitive candidate for industrial‑scale deployments provided site planners account for the ancillary cooling plant, robust power provisioning, heat recovery opportunities and pool/firmware selection as levers to optimise uptime, unit economics and asset lifecycle.

Deep dive
Bitmain Antminer S21 Plus Hydro — In Detail
Bitmain Antminer S21 Plus Hydro (358TH/s) — a closer look at the hardware and how it performs.
Like a strategist assessing a battlefield, one recognizes the Antminer S21 XP+ Hydro as a purpose-built SHA‑256 machine that balances raw force with l…ogistical demands. It produces 358 terahashes per second while drawing 5,370 watts, which translates to roughly 15 watts per terahash and anchors capacity planning and cost models. The hydro cooling is the operational core and keeps die temperatures low, which reduces thermal cycling and extends component life. That cooling, however, requires closed-loop coolant management, water treatment, pump redundancy, leak detection and routine maintenance to be treated as primary infrastructure items. The miner’s compact footprint of 410 x 170 x 209 mm and its Ethernet interface ease physical and network integration into dense racks, and its noise level near 50 dB permits closer placement to monitored zones. The specified operating window of about 5–45°C and humidity tolerance of 5–95% should be interpreted conservatively, with controlled environments preferred to prevent condensation and protect long-term reliability. Site planners must factor in robust power provisioning, power quality measures and heat-rejection systems, and they should evaluate heat recovery as a way to improve overall site economics. For operational resilience, operators should pair redundancy in cooling with firmware and pool strategies that optimize uptime and reward stability. When scaled, the unit’s high hash rate and repeatable energy profile make it a competitive option for industrial deployments, provided profit projections, maintenance cycles and lifecycle replacement are modeled and aligned with market volatility and regulatory constraints.
