I know others have posted about this issue before, but I'm trying to figure out how to identify which component is the problem ...
So, here are the relevant specs:
CPU: Intel i5-6600
PSU: Corsair CX 650M
RAM: 16 GB
GPU: Nvidia GeForce GTX 980
Everything was working fine for a while (at least a year). Then, all of the sudden, the computer started shutting off suddenly when the GPU was under load (i.e., while I was playing games). This happened 2-3 times, then the computer no longer booted up at all. Ultimately, I had to replace the motherboard, processor, RAM, and the PSU (which didn't cost me anything because those components were still under warranty). Verdict at the time was a faulty PSU. Things were working fine for about 3 months, when the issue started happening again now. I was able to trigger the computer shutting off by simply running a graphics benchmarking program.
So, i figured this time that it's somewhat unlikely I got 2 bad PSUs in a row, so I decided to change one of the few remaining components that I hadn't replaced previously: the GPU. Fortunately, I still had my old GTX 560 lying around, so I stuck that in, updated the drivers, and ran the same benchmarking program. No shutoff!
So ... my question now is, do I truly have a bum graphics card (the GTX 980, I mean)? Or is the PSU I went with not actually sufficient to run it under load despite the fact that Nvidia says that the power requirements are 500 W and I have 650? The power requirements of the GTX 560 are definitely lower, according to nVidia, so is it just that I need a better PSU? I could replace the graphics card with a new one, I suppose, but that's a lot of money to spend if all I really need is a different PSU. Just seems odd that everything worked fine for a while with this set up and all of a sudden it stopped working?
