Step-by-Step Fix
1
Verify the power outlet is working by testing with another device.
2
Check the power cable for damage and try a different C13/C14 power cord.
3
Check that the input voltage matches the PSU rating (110V vs 220V).
4
Disconnect all hashboard power cables from the PSU and try powering on with only the control board connected.
5
If PSU still does not power on, the internal fuse or MOSFETs may have failed.
6
Replace the PSU with a compatible model. Do not attempt to repair the PSU internals without professional experience.
