Question: Is it possible for a power supply dramatically frying itself to only slightly damage a graphics card? Or, is it far more likely to be something else?
I did a stupid and bought a cheapie 800 W power supply from AliExpress. (BTW: I think 800 W should have been more than enough for my modest system with nothing being overclocked.) Well, that power supply lasted me all of about 2 months. One day, after an electrical smell, I heard a loud "POP!" or "BANG!" and my system lost power. Sure enough, the power supply fried. I replaced it with the 1000 watt, high quality EVGA brand "1000G" supply I happened to have on hand and it seemed to work again just fine...
That was about 2 to 3 weeks ago. Lately, I've been experiencing serious issues with my graphics card. Seemingly all 3D games and applications will eventually cause the video to fail; That is, the screen goes blank and my monitor soon turns off because it fails to detect a signal. Though, often, I can still hear the music and/or sound fx in the background. (Other times, it hangs or goes silent.)
Strangely, pressing the {reset} button will not fix this. With a soft reboot, the video card still stubbornly refuses to give a signal that my monitor can recognize. Only by completely turning the machine off and then turning it back on will the card function properly again.
BTW: When I read the GPU turns off under any stress topic here in this forum area, I wondered if I had a similar problem. Someone suggested that the power cable going to the video card may be at fault and it might just lack power when it needs it.
It's true that I fiddled around with the power cables because I had to swap in a working power supply. So, I tried a few things to fix it:
Unfortunately, when I ran 3DMark and a game, it still crashed as usual. Nothing changed.

It's true that I fiddled around with the power cables because I had to swap in a working power supply. So, I tried a few things to fix it:
- Swapped out the PCI-E 6+2 pin "VGA" cable from the PSU with a spare I had.
- Inserted the PCI-E 6+2 pin "VGA" cable above into a different socket in my PSU. (It has several.)
- Pulled the Asus GTX 670 DirectCU II out of the PCI-E slot and re-inserted to make sure it has good connection.
- Pulled both the 24-pin EATXPWR cable and the 8-pin EATX12V cable and then re-inserted.
