Failure Paranoia & Prevention

[mav359]

Hey

 

Bought a bunch of new components, 3950x, Gigabyte X570 Master, Corsair HX750i, 32gb RAM ans 2 seagate M.2 drives

 

Turned up and after 9 days the MB died, sent it all back for testing and was told the MB was dead, all sent back 16 days go by and the same again. The MB was dead again, i had concearns over the PSU which they had tested and this time they said it was indeed faulty.

I insisted the change the MB to an ASUS ROG Crosshair VIII Hero and due to a lack of stock they upgraded the PSU to a HX850i. In my head i now feel that the motherboard died due to a faulty PSU and thats why i went through 2 boards and both have been replaced. The CPU, RAM and M.2s have been fine all along.

Its all put back together and working, there are no thermal issues and its not overclocked (other the XMP for 3200mhz RAM) The first failure happened with no UPS and the second it was plugged into a UPS, the only thing plugged in is an anker USB HUB and it connects to my AV Reciever via TOS-Link

Have i been really unlucky getting a bad PSU that killed two boards or is there something else that might have caused it? I have never heard of a component being faulty and killing a MB but remainined working itself, the CPU & RAM are fine, my 1080 has been fine all along

 

Is there anything else i could test or do as a preventative measure or anything i should be watching out for that might cause an issue, i have become super paranoid that i am going to have to rebuild this again

 

Cheers

The connections are all sound and the case grommets are all in place so theres no PSU cables rubbing against edges or corners. The UPS plugs into a mains socket which i have tested as good, im in the UK so everthing is earthed indivually and the UPS plus into that socket. My router, NAS, a small netgear switch and a single monitor plug into the UPS and none of them had any issue during the failure

 

Ive done plenty of builds in the past, i recently used 3 of the smaller Aorus mini-itx boards for PCs in work and they are all fine, i have just never had this kind of failure before and the fact it happened twice had me concearned especially cause it my own money

Yeah, it sounds like it was a faulty psu that killed the first two boards. Now that you are on a new power supply, you should be good.

X570 Master?
Your motherboard was not dead at all.

You had to physically remove the CMOS battery and then wait 30 seconds and then re-insert it.

 

This is a known issue, unfortunately.

I tried that myself, i have seen that happen before on other builds. PSU tested as faulty as well
