Hi everyone 

 

I'm in need of some help to identify what is my hardware prob here. 

 

I have a china x99 motherboard with xeon E5 cpu

Running unraid for months without any problem

 

Just last week, my flat had a power trip, after recovering the power supply to my flat. The unraid server is dead. I couldnt get it to boot. 

 

After some quick test, I suspect is the PSU that probably caused the power trip. I replaced the PSU with a new Seasonic PSU. While assembling back my server with the new PSU I have frequently test the PSU whether it is able to boot, and it worked. 

 

After I fully assembled the server, and turned the server on with a electrical monitor (attached). The server booted. But after I turn off the power and restart the server. The server is unable to boot. 

 

Similar test was done, and I suspect the PSU died again. 

 

The following components I'm suspecting could be the cause

 

- electricity monitor

- motherboard

 

May i know what is likely the cause? I lack the basic knowledge on hardware and electrical compoenents

 

What can cause a new PSU to breakdown this way? 

*Bump

How couldn't boot ?

 

PSU stay on ?

BIOS POST success ?

Success boot from USB ?

 

A short video may provide more info.

Sorry after dismantled the server right after I confirm that the new PSU is dead. 

 

Understand that it is vague without a video example. 

 

But can I find out if 

 

A electricity monitor can blow a PSU? 

A faulty motherboard can blow a PSU? 

A faulty graphic card can blow a PSU?

Very unlikely. The monitor only take reading and provide switch on off function.

All usually relate overload, but PSU have different kind protection, so also unlikely overload kill the PSU.

 

Any external fan controller use ? Any fan speed reduce adaptor use ?
