New EVGA PSU killed my drives?

Hardware Hub PSU
1

background: I have been using my Corsair HX850 for about 8 months on the current build of which i have pulled the drives mostly from old builds

system was :

4770k

MSI z87-gd65

corsair HX850 (before i put in the EVGA)

EVGA GTX 780

custom water loop

the drives in the system were were

1x 3tb seagate baracuda (newish: ~14 months old)

1x OCZ 120GB vertex 3 (old: ~3 years not in warranty)

1x samsung 250GB pro 840 (new: <7 months)

1x seagate 1tb baracuda (old: ~3 years not in warranty)

 

everything except the Samsung died when i installed my new EVGA supernova 850G2, i had used the PSU previously on another build as a test (thought my PSU on that build died) and then moved it to this build (for the fact that it was fully modular)

so the PSU worked fine on the other build and the moment that i move it to this one 3 drives die, instantly they are not showing in the bios so i move them all to different sata ports and they are still not showing up, the one drive that is working shows and i tested it on all the sata ports to verify they all worked (they did)then i remove the drives and test them on my HDD dock, the 2 mechanical drives don't spin-up and the SSD isn't working either (no equivalent for spinning up on a SSD) i checked them for any physical damage and didn't find any nor did i find scorch marks or water damage (also checked the loop for leaks but again there weren't any)

my conclusion is that my PSU fried them but I'm not sure why, i used 2 drives on the secondary build that are still working fine and my Samsung didn't die (however i am now having blue-screens on it) and i used the same cable and port on the PSU for both builds so i can't see it being the cable

so i want to RMA the PSU but do you think EVGA will reimburse me for the drives it fried (only one of them is within warranty) and how could i prove it was the PSU that was the cause (don't currently have a multimeter but ill go buy one to prove this if need be)

 

or what do you think the issue was?

 

Thanks.

Did you try using your old psu to confirm that your drives are dead. It is possible that the evga killed your drives or it could be something silly like the modular cables not plugged in all the way on the new evga psu.

i did check all the drives both on another power-supply and in a USB dock, no spinning/detecting on any of them, I believe I checked all the connections before i started them as I've always been cautious about this sort of thing. I will admit it could have been user error but I feel like its really not likely.

Either:

  • there was a nasty fault inside the psu = catastrophic failure, unlikely due to these units being rebadged superflower models add to that being probably one of the best psu designs on the market.
  • user error, if it first worked on one pc then not on the other something has gone wrong ie a short somewhere. Wrong cable, water spilt somewhere, power surge.

When you say all that was left was the samsung drive, do you mean that you gpu, mb, cpu etc got taken out as well?
