Questions & Answers
What mining performance does the Bitmain Antminer S21j XP Hydro deliver?
The Antminer S21j XP Hydro delivers a peak hashrate of 495 TH/s under the SHA-256 algorithm. This positions it among the higher-output hydro-cooled Bitcoin ASICs currently available, offering consistent and sustained performance for professional mining operations.
How much electricity does the Antminer S21j XP Hydro use?
It consumes 5940W under standard operating conditions, achieving an efficiency of approximately 12 J/TH. It requires a 380–415V industrial power supply, which is included with every unit at no additional cost.
Is the Antminer S21j XP Hydro noisy during operation?
No. Because it uses a closed-loop liquid cooling system rather than high-speed fans, the S21j XP Hydro operates at significantly lower noise levels than air-cooled miners. This makes it well-suited for high-density rack environments where acoustic control is important.
What is the weight of the Antminer S21j XP Hydro?
The net weight of the unit is 16.2 kg (16,200 g). Packaged dimensions are 570 × 316 × 430 mm, and the unit alone measures 430 × 176 × 208 mm.
Which cryptocurrency can the Antminer S21j XP Hydro mine?
It mines all SHA-256 algorithm coins. Primary use is Bitcoin (BTC), but it is also compatible with Bitcoin Cash (BCH) and Bitcoin SV (BSV). It is not suitable for non-SHA-256 coins such as Ethereum, Litecoin, or Dogecoin.
What are the physical dimensions of the Antminer S21j XP Hydro?
Unit dimensions (without packaging): 430 × 176 × 208 mm. Packaged dimensions: 570 × 316 × 430 mm. Net weight: 16.2 kg.
Does the Bitmain Antminer S21j XP Hydro include a warranty?
Yes. Every unit ships with a full 365-day (1-year) manufacturer warranty covering hardware defects and failures under normal operating conditions. Our support team is available to assist with any warranty claims.
