If I read this correctly, you have a problem in your AMD system and when you moved the PSU to a working Intel system, the Intel system started doing the same thing.
If true, this is a "Duh!" moment. If the problem follows the PSU, the PSU is bad.
i checked corsair psu output volt with multimeter . It seems to be fine . Moreover Amd cpu is brand new . Anyway Amd cpu motherboard , processor and psu is under warranty .
I have no idea about intel cpu . Which one is fault - motherboard or processor or psu
