    You can find all the technical information of the device on its label.

    Now, the actual setting up process begins.

    Step-by-step guide for setting up the Antminer S19j Pro+ 120T

    1. Preparing the ASIC

    • Place it on a flat surface where you have a wired network and in a relatively cool atmosphere, as the machine will release heat.
    • The power capacity and infrastructure for any ASIC miner are relatively high. The Bitmain Antminer S19j Pro+ 120T will require 3350W.
    • So, ensure you have 30 amps 240V PDU and circuit to run your Antminer S19j Pro+ if you’re in North America.

    PDU & Circuit

    • The S19j pro requires 2 C13 or C14 ports and 2 sets of C-13 to C-14 power cables to power the miner. You can get those power cables on Amazon.

    Ports Cables

    Ports & Power Cables

    • Ports & Power Cables
    • Ensure you get 14 gauge C-13 to C-14 cables, as the cable should handle the heat generated by the ASIC.
    • Plug the Ethernet cable into the miner, as no wifi support is available in Antminer S19j Pro+.


    • Now, plug the two C13 and C14 power cables into the ASIC miner.


    • Ensure all plugs are tight and there are no loose connections. Now you are all set to start the miner.

    2. Configuring the ASIC

    • Once the power supply is on, the ethernet light should come on.


    • Now you would need the IP address of the S19j Pro+. To get the IP address of the miner, you can choose any of the following steps:
      • You can use the free program software called Advance IP Scanner to get your miner’s IP address.
      • You can log in to your router and get the IP address.


    3. Accessing the S19j Pro via the Web Browser

    • Once you enter the IP address in the browser, a window will appear asking for a username and password.


    • Sign in to the browser by giving “root” as username and password. For all Antminer models, the default username and password is root. However, in other models from different companies, the credentials may vary. You can reach us at for assistance.


    • Now you can access the Web GUI of the Antminer S19j Pro+.

    4. Checking the Firmware

    Go to systems in the menu to check the firmware upgrades for the S19j Pro miner.

    firmware upgrade

    For instance, here it says, Saturday, March 11, 2023.

    • Next, go to the Bitmain page and check the published date of the firmware.

    bitmain site

    • If the dates are the same, you need not update the firmware. Else download the official firmware from Bitmain’s site. It is always recommended to use firmware from the manufacturer’s website as it helps you prevent viruses and unethical activities.

    5. Refining the Firmware

    • Go to the Antminer S19j Pro+ dashboard.
    • Select the upgraded firmware that you just downloaded. Check the keep the same settings box.

    • Click the update button and wait till the firmware is upgraded. It will take a few minutes.
    • Once done, you can see the dashboard displaying the updated firmware version.

    6. Adding the Mining Pool

    • Now, go to the settings page to set up the mining process by adding the mining pool, wallet address, and password.


    • You can check Mining Pool Stats to choose the mining pool to mine Bitcoin. You can research and select the pool that best suits your mining needs. For instance, let’s take for demonstration.
    • You need to make an account with any mining pool first. Log in to your account and get the mining pool address. Copy the mining pool address.


    • Paste it under the Mining address on the settings page.


    • Next is the miner’s name. You can find the miner name under the worker configuration. You can give the name of your choice.


    • Copy that name and paste it under the miner’s name.


    • Next, give the password of your choice and hit save.


    • That’s it. Your Antminer S19j Pro is now connected to the Bitcoin mining pool.

    7. Start mining Bitcoin

    • You can check the Antminer’s dashboard after a few minutes to know the mining status. The mining process should have started.
    • Sometimes, there may be a lag. You can always restart the miner to know the actual readings.


    • After the restart, you can see Antminer S19j Pro+ mine Bitcoins at the maximum hash rate of around 122th/s.


    • Here, the power consumption of Antminer S19j Pro+ is around 3376W.


    • However, the power consumption may fluctuate according to your environment.

    Bitcoin Mining Profitability

    The profitability of Bitcoin or any cryptocurrency is not predictable. It depends on various factors like mining difficulty, hash rate, electricity costs in your area, Bitcoin price, etc. Moreover, cryptocurrency prices are highly volatile, and thus miners should be watchful and study the market carefully. Here is the Bitcoin price history for your quick reference.

    Bitcoin Mining Difficulties

    Bitcoin follows the Proof of Work (PoW) mechanism. Thus, miners must solve complex mathematical algorithms to identify new blocks and mine new Bitcoins. Every cryptocurrency has a dedicated algorithm that constantly regulates the mining difficulty based on the number of miners in the network.

    The Bitcoin difficulty algorithm maintains stability in mining by setting a fixed time to find new blocks. Plus, the algorithm keeps increasing and decreasing the difficulty level in real time. For instance, the protocol decreases the mining difficulty if only a few miners are in the network, allowing the miners to discover blocks faster. In contrast, the algorithm increases the difficulty level if more miners are in the network.

    Mining difficulty is crucial as crypto mining is a decentralized process not governed by third parties. Otherwise, miners will discover blocks faster with advanced mining devices, making the entire mining process centralized and unpredictable. At times mining difficulty can reduce the mining profits, but it prevents cyber attackers from hacking the blockchain network. Thus mining difficulty ensures secure crypto transactions.
