🧊【Unboxing Review】Antminer S21+ Hyd. 395T Strong Debut: The Water-Cooled Beast Born for Computing Power!

Hello everyone! Today we bring you the highly anticipated water-cooled server — Antminer S21+ Hyd. (395T) unboxing and real-world experience. As Bitmain's latest achievement in water cooling technology, the S21+ Hyd. not only continues the stable and efficient design genes of its predecessor but has also made significant upgrades in energy efficiency and cooling systems. Next, let’s unveil its mysterious veil together!

📦 Unboxing Moment: Steady Industrial Style, Attention to Detail

When the delivery guy solemnly handed the large box to me, I knew this server was extraordinary. Upon opening the packaging, the first thing that caught my eye was the main unit tightly protected by foam, with a silver-gray metal exterior that has sharp lines and an overall solid workmanship. The dimensions of the whole machine are 339 x 173 x 207 mm, with a net weight of 12.3 kg, making it feel very “steady” when handled.

The packaging also includes an installation manual, water cooling pipe interface (DN10), and a power cable, with complete accessories for worry-free installation.

🔧 Hardcore Configuration Overview: 395TH/s Roaring Computing Power!

Let’s first take a look at its core parameters:

Project Parameter

Algorithm SHA-256

Supported Cryptocurrencies Bitcoin / BCH / BSV

Typical Computing Power 395 TH/s (±3%)

Power Consumption 6320W (±5% @35℃)

Energy Efficiency Ratio 12.0 J/TH (35℃)

16.0 J/KH (25℃)

Network Interface RJ45 Ethernet 10/100M
