This applies to all Antminer APW series PSU.

Follow the below steps to test if the PSU is broken or not: 

1. Make sure the power cord is plugged properly.

2. Set the multimeter to D/C to check the D/C voltage of the PSU.

3. There are two methods to plug the probes:

• Connect either red or black probe to the yellow and black connectors.
• Plug either red or black probe into the positive and negative terminals of the PSU.

4. Check the voltage readings, if it shows 12 ± 0.5 V, it means that the PSU is working fine. If it shows 0 V, it means the PSU is not working and needs to be repaired.

Create a repair ticket and return the PSU to us for repair.
