Buy 10 Units Refurbished Bitmain Antminer S9j 14.5Th With New APW7 PSU – Reliable & Efficient Bulk Mining Package
The Bitmain Antminer S9j 14.5Th continues to be one of the most cost-effective and dependable ASIC miners for Bitcoin (BTC) and Bitcoin Cash (BCH) mining. When paired with new APW7 power supply units (PSUs) and purchased in a refurbished 10-unit bulk package, this setup offers miners an accessible path to scalable hash power with strong performance and managed operating cost.
The Antminer S9j series has a long track record of stable hashing performance and robust hardware design, making it a popular choice for miners who want a solid return on investment without immediately stepping up to the newest generation of miners.
What Is the Bitmain Antminer S9j 14.5Th Miner?
The Antminer S9j is part of Bitmain’s S9 series, which has been widely adopted in the mining community for its consistent SHA-256 algorithm performance. This model delivers a hashrate of approximately 14.5 terahashes per second (14.5Th) and is capable of mining both Bitcoin (BTC) and Bitcoin Cash (BCH).
Unlike GPU or general-purpose mining hardware, ASIC (Application-Specific Integrated Circuit) miners like the S9j are built for one task — efficiently performing SHA-256 hashing computations. This specialization enables them to deliver higher hash output, better energy use, and long-term operational stability.

Why Choose This Bulk Refurbished Package?
📈 1. Affordable Hash Power Scaling
Buying 10 units together significantly boosts your mining capacity compared with buying single miners. Refurbished rigs reduce upfront costs while providing proven performance, and new APW7 PSUs ensure stable power delivery.
⚡ 2. Consistent Mining Performance
The S9j is known for stable operation, especially when properly powered and ventilated. Mine Bitcoin and Bitcoin Cash reliably with hardware that has been tested and configured for performance.
💸 3. New APW7 PSU Support
Each miner comes paired with a new APW7 PSU, designed expressly for Bitmain equipment. This means less guesswork matching power supplies and better consistency in power delivery.
🛠 4. Refurbished but Reliable
Refurbished miners are often returned units, tested, repaired, and verified to meet expected hashrate and power draw standards. This offers strong value for miners with technical experience or infrastructure in place to support multiple units.
Mining Bitcoin & Bitcoin Cash – How It Works
The Antminer S9j is optimized for the SHA-256 hashing algorithm, which is used by both Bitcoin and Bitcoin Cash. Because these coins share the same mining algorithm, your mining pool configuration can switch between BTC and BCH as profitability changes.
Basic Mining Setup:
-
Prepare a cool, ventilated environment with adequate space for heat dissipation.
-
Connect each miner to stable AC power via the new APW7 PSU.
-
Attach Ethernet cables to your local network.
-
Load each miner’s configuration dashboard via a browser.
-
Enter your mining pool settings and wallet address.
-
Save settings and begin hashing.
Once the units begin hashing continuously, they’ll contribute shares to your selected pool based on your total ~145 Th/s combined output.
Profitability Considerations
Mining profitability depends on several dynamic factors:
-
Bitcoin / Bitcoin Cash market price and volatility
-
Current network difficulty and total hash rate competition
-
Electricity cost per kilowatt-hour (kWh)
-
Mining pool fee and payout structure
-
Uptime and cooling efficiency of your miners
Because these units are refurbished, your initial purchase cost is lower, which can improve breakeven timelines when compared with new hardware. However, it’s important to calculate expected earnings using current difficulty and price data specific to your region’s electricity cost.
Ideal Use Cases for This Package
This bulk refurbished Antminer S9j 14.5Th package is ideal for:
