AX760i issues

Hi,



I built my pc the last week and since, I meet some issues with my PSU.

The first days, my pc crashed 3 or 4 times but no reason, no BSOD or anything else. Just switch off and the PSU put itself in safe mode. Have to unplug and restart the PSU to reboot my PC.

I did a OCCT stress test and every tensions are good.



But this morning, it doesn't work at all. PSU stays in safe mode and I'm just hearing an "clic" aaaaand ... stop. No boot, no Windows, nothing but my tears. :D:



So, I have unplugged everything, just keep the 2 connectors for the motherboard and anything happened.



Then, I put my PSU spare (Akasa 750W) to replace the Corsair and the pc turns really well now.



But I really don't understand where the problem is.

When I do a self test, the green light switch on and when I plug on the motheboard, it's immediatly in safe mode ...



Should I send my PSU to Corsair ?

Thanks for your help (and sorry for my english).
