Should I replace my PSU? If yes, with which of the following options?

And I wouldn't particularly call a C-tier PSU trash. Sure, the 750GQ
i call it trash because i have two of them... or had.
one died after two years and the other one makes extreme coil whine noise and the fan rattles. :D

Well, since I saw your parts list in another thread, I am by no means surprised you have some issues from time to time :laugh:
My 750GQ is a warrior, now honorably discharged after ~5 years of service. And hopefully, it'll still serve me by recouping some of the cash spent on the new Cougar.

So the problem really was the PSU, eh?
Looks like. And no kidding, during the exact HZD benchmark there were some 410W+ readings on the Radeon overlay now with the new PSU. Still under observation, but the path looks good.
 
The 7900XTX is waaaay more spikey, or sensitive, or maybe both than any other card I've ever had. It's wild.
