sunbin Posted May 26, 2023 Share Posted May 26, 2023 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? Quote Link to comment
Vr2Io Posted May 27, 2023 Share Posted May 27, 2023 How couldn't boot ? PSU stay on ? BIOS POST success ? Success boot from USB ? A short video may provide more info. Quote Link to comment
sunbin Posted May 27, 2023 Author Share Posted May 27, 2023 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? Quote Link to comment

The monitor only take reading and provide switch on off function. 17 hours ago, sunbin said: A faulty motherboard can blow a PSU? A faulty graphic card can blow a PSU? 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 ? Quote Link to comment
