My PC dies few seconds after start.

Ok so a week ago my computer started doing something wierd. When I would start it up, it will freeze at win loading screen, then I had to shut it down, wait about an hour, then it would finally start up. If I would start it right away, it would start and die in a second or two. If I wait only 30 minutes it would only load half way before dying. Now no matter what I do, I cannot start it at all. It would die in a second or less. I tried to replace my RAM and my hard drive with what I had around, and it would not start, so they are not the problem. I am suspecting it is my PSU, since I had the same problem before which I fixed by replacing PSU, but it may aslo be CPU, since I always had problems with it and I think it was defective when I bought it. Here are my specs:

ASUS Crosshair V Formula-Z AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard
AMD FX-9590 4.7GHz 8-Core OEM/Tray Processor
Corsair Vengeance Pro 32GB (4 x 8GB) DDR3-2400 Memory
EVGA GeForce GTX Titan X 12GB HYBRID Video Card
Seagate ST1000DM003 7200rpm HDD
EVGA Supernova 850 P2 PSU

Pretty sure it is your PSU.

I am too. Today I going to bring my PC to a repair shop where they do a free diagnosis. I don't have a powerful enough PSU around to make sure it is my PSU that has failed before I order another one.

Ok, I got it fixed. It wasn't my PSU, but it was a cord that was connecting my GPU to my PSU.
