The Bitmain Antminer S23 Immersion 442Th/s Bitcoin ASIC Miner is purpose-built for immersion-cooled Bitcoin (BTC) mining on the SHA-256 algorithm. If your build is dielectric-tank-ready, this is the kind of unit that turns your facility into an efficiency-per-square-foot leader.
Here's what you actually get. The Bitcoin ASIC delivers 442 TH/s of hashrate at the 9.5 J/TH efficiency, and on a unit at this hashrate tier, efficiency is the number that decides whether your operation is profitable at any given power cost. Anywhere above $0.06/kWh, the efficiency gap between this unit and older hardware compounds into real revenue over a year of uptime.
Immersion cooling changes the economics of mining at scale. Chips run cooler, so they hash longer and degrade slower. Density goes up, because tanks pack tighter than air-cooled racks. Noise effectively drops to zero, which opens up siting options most air-cooled farms can't touch. If your facility is already dielectric-fluid-ready, the Bitmain Antminer S23 Immersion 442Th/s Bitcoin ASIC Miner drops straight in.
Order direct from The Miner Island with free DDP shipping on orders over $5,000, we handle customs, you don't see a separate import bill. Pay with Bitcoin and save 3% on your entire order. Every unit is tested for stable hashrate before it ships.

Every order over $5,000 ships DDP-paid from our Hong Kong warehouse, so duties, taxes, and customs clearance are paid before the unit reaches you. You won't get a surprise invoice from the courier on delivery day.
Most orders dispatch within 24 to 72 hours of payment confirmation. Transit time runs 3 to 7 business days to North America, Europe, and the major mining jurisdictions. We share the tracking number the moment the airwaybill is issued.
Every unit carries a 60-day warranty from the date you receive it. Manufacturer warranties (typically 180 to 365 days depending on the brand) run in parallel and we'll help you process those claims directly with Bitmain, MicroBT, Canaan, Goldshell, IceRiver, or Elphapex.
If your unit arrives dead-on-arrival (won't power on, fails the initial hashrate test, or has visible transit damage), we replace it. Document the issue within 72 hours of delivery (a short video or photo set is enough), and we'll ship the replacement.
We accept Bitcoin, Ethereum, Litecoin, USDT, USDC, and a handful of other major cryptos through Plisio. Pay in any crypto and save 3% on your entire order. The discount applies automatically at checkout. For bulk orders over $25,000, message us on WhatsApp to discuss 50/50 staged crypto payment options.
Live estimate based on this unit's hashrate, efficiency, and coin price.
Network difficulty, coin price, and uptime all move. Treat this as a sanity-check, not a guarantee. Baseline issuance data is calibrated to May 2026; numbers drift as networks evolve. We're happy to walk through your specific power cost and target hashrate on WhatsApp.
