Bitcoin Asic Antminer S21 Hydro 335 TH/s 5360W

Bitmain Antminer S21 Hydro is an advanced model of cryptocurrency mining equipment, specially designed for SHA-256 algorithm. It boasts an impressive maximum performance 335 terahas per second (Th/s), which is an indicator of its computing power and mining efficiency. This high performance makes the Antminer S21 Hydro among the most powerful mining rigs on the market in 2023-2024, making it ideal for mining Bitcoin and other cryptocurrencies using the SHA-256 algorithm.

However, this high performance is associated with high energy consumption. Antminer S21 Hydro consumes approx 5360 watts (W) electricity. This level of energy consumption requires a stable and cost-effective energy source to make mining profitable. The high power consumption also means that this mining rig generates a significant amount of heat, which must be efficiently dissipated to maintain the long-term life and efficiency of the hardware.

With these specifications in mind, the Antminer S21 Hydro is best suited for professional or industrial mining operations where the infrastructure is capable of supporting its power and cooling needs. As with any mining rig, potential users should consider the cost of electricity in their location and the current state of the cryptocurrency market to assess the profitability of using this rig.

Duležité upozornění: It must be purchased to ensure optimal operation and cooling of the device special cooling system. We offer this system in our menu and you can order it here: [link to cooling system]. Without this cooling, heat cannot be dissipated effectively, which could negatively affect the performance and lifespan of the device.

Questions and answers Q & A

how loud is Antminer S21 Hydro David asked on March 12, 2024

Hello, the volume of your hydro ASIC miner will depend on the way you arrange hot water drainage and cooling. If you buy a water cooling radiator from us, this radiator is equipped with 9 fans that operate at a noise level between 55 and 65 dB. Furthermore, the volume will also depend on the conditions in which the device will be operated. For example, if you use this ASIC miner to heat the floor, in winter the noise should be minimal, because the temperature in the room will be lower and therefore the need for cooling will be less. On the other hand, in the summer, it will probably be necessary to deal more with the drainage of hot water to the radiator, which can slightly increase the noise level of the system. It all depends on the specific conditions and how you use your device.
