Replacement tutorial for Antminer APW12 12V-15V PSU E version

The APW12 1215e PSU has an input voltage of AC 200V to 240V and an output voltage of DC 12V to 15V. It features built-in protections against undervoltage, output short circuit, overload, over-temperature, and more. It provides reliable assurance for the long-term stable operation of Bitmain Antminer S19 Pro, S19j Pro, and S19XP air-cooled miners. Additionally, the APW12 1215e can replace the APW12 1215 a, b, and c versions through firmware upgrades.

When our Antminer S19 Pro, S19j Pro, or S19XP miner encounters issues such as failure to power on, non-working fans, unbooted control boards, or non-illuminated indicator lights after being powered on, these may be caused by a power supply malfunction. In such cases, we should promptly replace the PSU with a new APW12 1215e to restore the miner's normal operation and save on repair time to minimize downtime losses.

Taking the Antminer S19 pro miner as an example, the replacement steps for the APW12 1215e PSU are as follows:

1. Remove the bezel above the power supply unit and unplug all cables.

2. Use a screwdriver to unscrew the conductive copper sheet screws and remove the conductive copper sheet.

3. Unscrew the screws securing the power supply and slide it out along the card slot before remove it.

4. Check if the new PSU is intact, then align it with the rails on the side of the miner, install it, and secure it with screws.

5. Connect all cables, install the conductive copper sheets, and tighten the screws to ensure the restoration of the power supply connection to the control board and hash board.

6. Start the S19 pro miner and check its operating status to ensure it is functioning normally, indicating a successful replacement.

In the increasingly competitive mining market, maintaining the uninterrupted operation of miners is crucial for obtaining stable returns. When the power supply of the S19 Pro, S19j Pro, or S19XP miner malfunctions, please replace it promptly to quickly restore the miner's operation, ensure continuous earnings, and avoid further losses due to downtime.
