#BTC# Antminer U3S21EXPH unboxing review: a newcomer in the mining industry, a double leap in performance and efficiency
In the field of cryptocurrency mining, every new product release touches the hearts of countless miners. Today, Li Yi editor is fortunate to bring you an unboxing review of Bitmain's latest masterpiece, Antminer U3S21EXPH. This server, scheduled to be released in December 2024, has become the focus of industry attention with its amazing 860 Th/s hash rate and innovative liquid cooling technology.
Unboxing first impression
First of all, the moment you take Antminer U3S21EXPH out of the box, you can feel its extraordinary industrial design. The overall size of the server (excluding packaging) is 900486.2132 mm. Although it is not small in size, it has smooth lines and the metal shell reveals a calm and powerful atmosphere. Due to the use of a liquid cooling system, the U3S21EXPH is more compact in appearance than traditional air-cooled servers, reducing the space occupied by fans and heat sinks, making the overall layout more reasonable.
Performance test
As the performance indicator that miners care about most, the 860 Th/s hash rate of Antminer U3S21EXPH is undoubtedly impressive. This number not only represents its powerful computing power under the SHA-256 algorithm, but also means a major leap in mining efficiency. At room temperature of 25°C, its power consumption is 11610W. Although this number seems not low, it is only 13.5 when converted into an energy efficiency ratio (J/T). Compared with similar products, this result is already quite outstanding, showing Bitmain's deep foundation in energy efficiency optimization.
The charm of liquid cooling technology
The liquid cooling system is undoubtedly a highlight of Antminer U3S21EXPH. Compared with traditional air cooling, liquid cooling technology can more effectively remove the heat generated by the chip and maintain the stability of the server under long-term high-load operation. This not only extends the service life of the hardware, but also significantly reduces the noise level. The noise level is only 40dB in actual measurement, almost reaching the library-level quiet effect, providing miners with a more comfortable working environment.
Network connection and operation convenience
In terms of network connection, Antminer U3S21EXPH is equipped with an RJ45 Ethernet interface, supporting 10/100M network connection, ensuring the stability and speed of data transmission.
