The Bitmain Antminer S21 XP Immersion (300Th) SHA‑256 BTC ASIC miner listed by Guangdong Technologies Ltd is a state‑of‑the‑art device built specifically for Bitcoin mining. It provides a hash rate of 300 TH/s, as stated in the product title and confirmed by the supplier’s description. The unit arrives with the standard power module, control board and immersion‑compatible chassis, and the supplier notes ISO‑based quality assurance. Guangdong Technologies Ltd highlights a user‑friendly web interface for setup and monitoring.
Immersion cooling replaces traditional fan arrays, allowing the miner to operate with lower acoustic noise and improved component lifespan. Typical power consumption for a 300 TH/s immersion unit is around 4,800 W, resulting in an efficiency close to 16 J/TH. Standard dimensions for this class are roughly 350 mm × 190 mm × 160 mm and the equipment usually weighs about 10 kg, both marked as typical industry figures. Common safety certifications such as CE and RoHS are often applied to Bitmain ASICs, although the supplier only explicitly mentions ISO compliance.
The miner is suited for cryptocurrency mining farms, data‑center operators and businesses entering the Bitcoin mining sector. Buyers benefit from flexible minimum order quantities and the ability to choose FOB or CIF shipping. Payment options include letters of credit and telegraphic transfer, but exact terms should be verified with Guangdong Technologies Ltd before finalising any contract.

When ordering, ask the supplier to provide a detailed data sheet confirming the hash rate, power consumption and immersion cooling specifications, as well as any test results for thermal performance. Verify that the unit includes all listed accessories, such as the power supply and control board, and request serial numbers or batch codes for traceability. Checking the supplier’s response channels and their ISO‑based quality statements helps ensure reliable communication throughout the procurement process.
Shipping from China typically involves FOB or CIF incoterms; request the exact port of loading and an estimated lead time for production and dispatch. Clarify whether the seller accepts letters of credit, telegraphic transfer or other payment methods, and ensure that any required customs documentation, such as commercial invoices and packing lists, are prepared in advance to avoid clearance delays.
Implement a quality assurance plan that includes a pre‑shipment inspection covering electrical safety, immersion fluid integrity and functional performance. Request a factory test report and copies of ISO, CE or RoHS certificates before the goods leave the factory. Arrange for an independent third‑party inspection if needed, and confirm that the supplier will provide warranty registration documents upon delivery.
