What Is the Bitmain Antminer S21 XP+ Hyd?
The Bitmain Antminer S21 XP+ Hyd is a hydro-cooled Bitcoin miner delivering 500 TH/s at about 5,500 W, an efficiency of 11 J/TH. Bitmain's November 2025 manual documents a family of 460T, 480T, 500T and 520T sub-models, all rated at the same 11.0 J/TH.
The S21 XP+ Hyd is the mature option for operators who want liquid cooling without waiting on S23 allocation. Because Bitmain shipped several binned variants at identical efficiency, buyers can match hashrate to available circuit capacity instead of over- or under-provisioning power.
It shares the compact standalone chassis format of other S21 hydro units, at roughly 339 × 173 × 207 mm and 14.2 kg, which makes it straightforward to shelf-mount alongside existing S21 rows on a shared coolant manifold.

Antminer S21 XP+ Hyd Power Consumption & Electricity Cost
The Bitmain Antminer S21 XP+ Hyd is rated at approximately 5500 W at the wall. Electricity is usually the largest recurring cost of running it, so estimate the draw at your own rate before committing to a deployment.
- Cost per hour
- $0.39
- Cost per day
- $9.24
- Cost per month (30 days)
- $277.20
Based on a rated draw of 5500 W at 100% uptime: power in kW × 24 × your rate. Real consumption varies with firmware, ambient conditions and uptime.
Antminer S21 XP+ Hyd Hydro Cooling Requirements
The Bitmain Antminer S21 XP+ Hyd is a liquid-cooled unit. It has no onboard fans for the hashboards: heat is carried away by coolant circulating through a cold plate and must be rejected by external infrastructure — typically a dry cooler, cooling tower or plate heat exchanger sized for the site's total heat load.
A hydro deployment needs a closed loop with pumps, manifolds, filtration, quick-disconnect couplings and coolant treatment. Plan for water quality control and leak detection, and match manifold sizing to the number of units per row so flow rate stays inside the manufacturer's window.
The payoff is density and acoustics. Hydro units run far quieter than air-cooled miners, tolerate higher ambient temperatures, and let operators pack substantially more hashrate into the same floor area. Heat recovery is also practical, because the rejected heat leaves the machine as warm water rather than hot air.

Efficiency (joules per unit of hashrate) determines how long a machine stays profitable as network difficulty rises, while total power draw determines what electrical and cooling infrastructure you need per unit. A more efficient miner is not automatically the better purchase — price per terahash, availability and the cost of the cooling infrastructure it demands all feed into the decision.

Frequently Asked Questions
What is the S21 XP+ Hyd hashrate?
500 TH/s in the 500T-10 configuration at approximately 5,500 W (11 J/TH).
Are other hashrate versions available?
Yes — Bitmain's manual lists 520T, 500T, 480T and 460T variants, all at 11.0 J/TH.
How does it compare to the S23 Hyd?
The S23 Hyd produces 580 TH/s at 9.5 J/TH, so it is both faster and more efficient. The S21 XP+ Hyd usually wins on availability and price per terahash.
What power input is required?
380–415 V three-phase, per Bitmain's product manual.
How loud is it?
About 50 dB, since cooling is handled by external pumps and heat rejection rather than onboard fans.
