Are you using a UPS with your computer?
If no, maybe running the comp off the mains might be causing the system to die prematurely. Or it could be just bad luck.
About your confusion, don't change your psu or downgrade it. From vx450 onwards you have used good psu choices.
Go ahead with option 1.
I m using APC UPS. With VX450 I was using 500VA one and now 1.1KVA one. Hence it appears that its sheer bad luck.
For going with option 1 please suggest me a good motherboard, a non-Gigabyte one. I m mostly not keen to overclock though initially I had it in my mind. I need good after sales service, rest is fine with me. Also there is a peculiarity with this motherboard, PCI-E slot is in line with SATA ports. So bigger cards like mine create issues. I can stretch my budget till 6K, lower the better.
