Bitmain Antminer S21e XP Hyd 430 TH/s SHA-256 Hydro Bitcoin Miner

It delivers 430 TH/s of SHA-256 hashrate at 5,590W, which works out to 13 J/TH. Bitmain's ±3% tolerance puts real-world output in the 417 to 443 TH/s range. That places it in the middle of Bitmain's hydro lineup, more efficient than the older S21+ Hydro and a step below the newest S23 Hydro flagship.

Any SHA-256 proof-of-work coin. Bitcoin is the primary target, and the same hardware mines Bitcoin Cash, Bitcoin SV, Fractal Bitcoin, Namecoin and other SHA-256 chains. Merged mining Bitcoin alongside compatible chains through supporting pools can add marginal secondary rewards.

An external closed-loop water cooling system. The miner has no fans of its own; it moves roughly 5.6 kW of heat into a sealed loop that runs to a dry cooler or heat exchanger sized for your fleet, with circulation pumps, filtration and flow monitoring. It uses the same cooling setup as Bitmain's other S21 hydro units and works with water or water-glycol loops.

About 5,590W continuous through Bitmain's P33 connector and PW12V1 PDU, which accepts single-phase or three-phase supply depending on how the facility is wired. In practice these run in hosted sites and dedicated hydro rooms on industrial-grade power rather than a standard household circuit. Confirm the exact input voltage for your batch with our team before you wire the site.

It is built for hosted and farm-scale hydro deployments rather than a living room. Even setting power aside, it needs an external water-cooling loop with pumps and a heat exchanger, which is impractical to build at home. If you want the S21e XP Hyd without running the infrastructure yourself, hosting it in our US facilities is the simplest route.

The chassis itself runs around 50 dB because it has no onboard fans, quiet enough to stand beside. The noise in a hydro operation comes from the external cooling plant, the pumps and dry coolers, which professional sites place away from the miners to manage the overall sound.

New units ship with the power supply, cables and a quick-start guide alongside the miner, tested before dispatch. Contents can vary slightly by batch, and the exact items are listed on your order confirmation.

A Bitmain factory warranty of 12 months on the machine, covering manufacturing defects and hardware failures under normal operation within the rated environment. Coverage excludes damage from coolant neglect, leaks from improper fittings, power surges without proper protection, and unauthorised firmware. Confirm the current warranty terms with us at the time of purchase.

Yes. Braiins OS+ supports the S21e series with autotuning that can improve efficiency through per-chip frequency optimisation, and Vnish and LuxOS also support the hardware. Third-party firmware typically voids the Bitmain warranty, so most operators run stock firmware during the warranty period and consider tuning afterward.

Yes. We run hydro-capable US facilities and can deploy the S21e XP Hyd for you, covering power, cooling and uptime while you keep ownership. If you take delivery instead, every unit ships worldwide DDP with customs and duties handled, so the price at checkout is the final landed cost.
