New ASIC Miners, Sealed with Factory Warranty

New ASIC miners, sealed from the manufacturer, with the factory warranty intact and no prior run hours. This is the section to buy from when uptime matters more than entry price — hosted deployments, financed builds, and any site where a dead unit costs you more in downtime than the machine cost to buy.

What you are paying extra for

Three things, and it is worth being blunt about them. First, warranty: a factory warranty on a current-generation machine is the difference between a failed hashboard being a claim and being a repair bill. Second, known history — nobody has overclocked it, run it at 90°C in a shed, or flashed it. Third, current efficiency. A new S21-class machine at 13–15 J/TH will still be economic long after the S19 generation has been shut off.

What you are not paying for is more hashrate per dollar. Used hardware wins that comparison every time. If your power is cheap and your tolerance for maintenance is high, read the case for used and refurbished units before you buy new.

How to choose inside this section

Match the algorithm to the coin you actually intend to mine. SHA-256 machines (Antminer, Whatsminer, Avalon, Bitdeer) mine Bitcoin. Scrypt machines mine Litecoin and Dogecoin together. The altcoin ASICs mine exactly one chain each and cannot be repointed.

Match the cooling to your infrastructure, not your ambition. Air-cooled units run anywhere with a 240V circuit and airflow. Hydro and immersion models in this section will not run without a loop or a tank already built.

Check the batch. Several listings here are batch-dated. A January batch is a delivery window, not stock on a shelf, and the difficulty at delivery is not today’s difficulty. Ask us for the current lead time before you commit — we will give you the real date rather than the optimistic one.

Who this suits

Operators sizing a new build, anyone deploying to a hosting facility with an uptime SLA, and buyers who want a warranty to point at. If you are experimenting, learning, or building a small home setup, buy used and keep the difference.

New hardware earns its premium through efficiency, and efficiency is what sets the electricity price you can survive. The ASIC miner buying guide works through J/TH, real monthly power cost and 2026 hosting rates in detail.

Buying new comes down to efficiency per dollar, not terahash per dollar. The Antminer S21 Pro 245T at 15 J/TH and the Antminer S21+ 216T at 16.5 J/TH are the two SHA-256 machines worth putting side by side first. If you are mining Scrypt rather than Bitcoin, the Antminer L9 17G is the equivalent starting point.
