Replace tutorial for the P222C PSU of Whatsminer M30 M50

For miners seeking an efficient mining experience, the Whatsminer P222C PSU is undoubtedly the best replacement for the faulty power supply of M30 and M50 miners. It can stably output a voltage of 12V to 14.5V to ensure the continuous, stable operation of the miner. The shell made of high-quality steel effectively protects the internal components of it from external environmental erosion or damage while extending its service life. In addition to the M50 miner, it's also widely applicable to various models of miners, including M20, M30S, M30S+, M30S++, M31, M32, and M31S.

The power supply plays a crucial role in the miner's operation. When abnormalities such as the inability to turn on, frequent reboots, or sudden power outages occur in a miner, it is very likely caused by a power supply failure. At this time, we should immediately replace the faulty one to ensure that the machine can quickly resume normal operation, thus safeguarding the stable income of miners.

Taking the Whatsminer M30 miner as an example, the detailed steps for replacing a faulty P222C power supply are as follows:

1. Remove the faulty power supply

• Power off the miner. Note: Please do not operate with electricity.

• Remove the outer shell of the control board.

• Detach the fixing screws of the PSU on both sides and the conductive copper sheet of it. Disconnect the connection cable of the inlet port fan and the control board.

• Take out the faulty PSU.

2. Install the new power supply

• Before installing the new power supply, carefully check its appearance and labels to ensure that its model is compatible with the miner without damaged.

• Align the new PSU with the fixing screws on both sides.

• Tighten the conductive copper sheet and the fixing screws. Connect the previously disconnected cables, ensuring that each cable is securely connected.

3. Power-on test

• Re-power the miner and start it. Carefully observe the operating status of it to ensure that the new power supply can provide stable powering.

As the heart of a miner, the health status of the power supply is directly related to the overall operating condition of the machine. Therefore, we need to replace it promptly once a power supply failure is discovered, so that the miner can quickly restore the normal operation to achieve stable income. Wish all miners a pleasant mining journey with abundant rewards.
