Replacement tutorial for Whatsminer M50 M60 P221B PSU

With its stable 12V voltage output, sturdy casing made of high-quality steel and wide applicability, the P221B PSU has become an ideal replacement for faulty power supplies in miners. It is not only suitable for the recently launched Whatsminer M50 M60 miners, but also compatible with multiple air-cooled miner models such as M60S, M30S++, M50S, M50S+, M50S++, M30S, M30S+, and M31S+.

When miner's power supply fails, it may result in voltage instability, increased noise, overheating, or even sudden power outages, which can seriously affect the normal operation and mining efficiency of the miner. To avoid potential losses, it is recommended to replace it with a reliable power supply unit in time to ensure that the miner can work continuously, thus improving mining revenue.

We will demonstrate the replacement steps of the P221B power supply making the M50 miner as an example:

1. Completely power off the miner to avoid safety risks caused by live operation.

2. Remove the protective shell above the control board, detach the fixing screws and conductive copper sheets on both sides of the power supply, disconnect the cables connected to the inlet port fan and the control board, then take out the faulty PSU.

3. Before installation, carefully inspect the appearance and labels of the new P221B power supply to ensure that it is compatible with the miner without damaged. Then, align it with the fixing screws on both sides, tighten the conductive copper sheets and the fixing screws.

4. Reconnect the cables that were disconnected before, ensuring that each cable is securely connected.

5. Re-power the miner, then carefully observe its operating status to ensure that the new power supply can provide stable powering.

The timely replacement of the Whatsminer M50 M60 damaged PSU is crucial for its stable operation, which can not only ensure mining efficiency but also avoid safety hazards. Hope miners friends a full harvest and pleasent mining!
