gtx 780 (new, replaced a gtx 650)
i5-4670k
16GB RAM
750w PSU (lepa, g750-mas)
I recently put a gtx780 into my computer, and on paper everything looked good, but since then my computer has been shutting off sometimes when I try to play a game. The computer will shut down, as if a power surge has happened. No blue screens, no warnings, no nothing. The computer boots right back on after it shuts down. There is also very little information given in the event log. Just tells me the computer suddenly shut down without warning (I'm also bad at reading event logs though).
Turning down the graphics settings in games seems to help. I tried playing Skyrim on max and it shut off right away, but after lowering everything to medium it allowed me to play (however, it has still shut off a couple times even with the medium settings). I'm not sure if that means its a GPU issue, or if the PSU just can't get enough power going when the graphics are turned up, or what. But I have no graphic issues when I do get a game going, everything runs smoothly.
I also don't believe it's a heat issue (but i'm no expert), since if the graphics are high the computer just shuts down right away, before the computer has even had a chance to heat up. While playing Skyrim on medium, temps were around 35-40c for both the GPU and CPU. The first time it shut down like this I was playing Tomb Raider on max. I think the temps were around 60 for the GPU, and maybe 50c for the CPU? I can't recall the CPU temp well. It also shut down once as soon as I turned the vertical sync off in WoW once.
The computer has yet to shut down when I'm just browsing the internet or doing whatever. Just when playing games. I'm almost certain it is the PSU but I would like some other opinions before I sink the money into a decent PSU.
