Information

Bitmain Antminer S21+ Hyd

Reviews

  • Manufacturer Bitmain
  • Algorithm SHA-256
  • Power connector LP20
  • Cooling Hydro
  • Release date February 2025

Description

The Antminer S21+ Hyd model from the world's leading manufacturer Bitmain is a high-performance solution designed for professional mining. This device combines advanced chip architecture, exceptional reliability, and optimized power consumption, making it one of the most sought-after tools in the digital asset mining industry. The model was released in February 2025.


Technical Specifications and Performance

The Antminer S21+ Hyd is powered by innovative components that ensure stable operation even under peak loads.


Key metrics of the device:

  1. Algorithm: Operates on the SHA-256 algorithm, which has proven to be one of the most secure and profitable in the network.
  2. Hashrate: The nominal computing power is 319Th, allowing it to compete effectively in today's network complexity conditions.
  3. Power Consumption: The device power consumption is locked at 4785 W, providing a perfect balance between performance and electricity costs.
  4. Energy Efficiency: The efficiency metric stands at 15 j/Th, which is a key factor for a fast return on investment.


Supported Assets

Due to the SHA-256 algorithm, this miner allows you to mine a wide range of cryptocurrencies. The list of the most relevant coins includes: Bitcoin, Fractal Bitcoin, Bitcoin Cash, BitcoinSV, Terracoin, Namecoin. This gives the owner flexibility in choosing a mining strategy and the ability to switch between assets depending on the current market situation.


Cooling System and Operating Conditions

The operational stability of an ASIC miner directly depends on the quality of heat dissipation. This model features an advanced cooling system.


The hydro cooling system utilizes special water blocks for direct heat dissipation from the hashboards. This allows completely eliminating noisy fans, making the device operation virtually silent. Hydro systems handle overheating significantly better, allowing the miner to be operated in regions with hot climates or allowing waste heat to be used for space heating. This type of cooling requires connection to an external water loop or cooling tower.


Advantages of the Antminer S21+ Hyd model

  1. Durability: The use of high-quality chassis materials and wear-resistant components guarantees a long equipment lifecycle.
  2. Intelligent Management: The built-in software allows tracking chip status, fan rotation speed (if applicable), and current revenue in real-time.
  3. Fast Configuration: An intuitive web interface allows launching the mining process just a few minutes after the first power-up.


Summary


Bitmain Antminer S21+ Hyd is the benchmark of quality in the mining world. The device is perfectly suited both for scaling existing farms and for those looking for the most effective solution to start. A high hashrate combined with clever power consumption makes this model a strategically advantageous acquisition for the long-term perspective.

Frequently Asked Questions

The Bitmain Antminer S21+ Hyd features cooling based on a water system. Hydro models demand an external water-loop distribution block or a dry cooling tower.. To initiate mining, plug in the LAN cable, scan your local network for the miner's IP using an ASIC Tool, open the web dashboard, and enter your target pool stratum addresses.
Currently, the best available price for the Bitmain Antminer S21+ Hyd 319Th/s ASIC miner on our platform is 2252 USDT. This listing is provided by GetAsic. You can review all current listings, evaluate supplier credibility using our Trust Factor badge, and proceed with a secure deal inside our catalog.
Upon conversion, the computing power of 319 Terahash/s is equivalent to 319 000 000 000 000 hash/s, 319 000 000 000 kilohash/s, 319 000 000 Megahash/s, 319 000 Gigahash/s, 0,32 Petahash/s. Depending on the coin algorithm, the baseline operational output denomination might be displayed in different network standards. To quickly convert any hashrate, solution, or graph volumes without manual calculations, use our dedicated hashrate converter tool on the TrustMining website.
Given the current network difficulty of 132,716,002,350,731 and a block reward of 3.125 BTC, a single Bitmain Antminer S21+ Hyd 319 Th/s will take approximately 6531 days to successfully secure 1 full Bitcoin. The device yields roughly 0.00015312 BTC or 15312 satoshi per day on average.
The Antminer S21+ Hyd rig is exceptionally data-efficient, utilizing only about 50 to 150 MB of network data per month per machine, as it only sends small textual cryptographic shares (work updates) to the pool server. The core requirement is connection stability and minimal network latency rather than raw speed (Ping to the pool under 50-80 ms). ASICs must be connected exclusively via a **wired LAN cable** (Ethernet).
If adequate cooling is maintained (ASIC chips under 75-80°C), dust is cleared regularly (every 6 months), and grid voltage stays stable, the Antminer S21+ Hyd can operate reliably for **3 to 5 years**. The most common components requiring eventual routine replacement are cooling fans.
