So interestingly enough, my PC seems to be able to run Cyberpunk 2077 well (or did), and I beat it multiple times on High settings; however, now when I go to play just about any game (such as Detroit: Become Human, or Life is Strange) my computer just "shuts down" and reboots. No warnings, screen goes black as PC shuts down ands restarts itself. Naturally I think heat could be an issue, or power - but the PSU is brand new (modular) and there is plenty of cooling and fresh thermal paste. I've looked all over on the internet for months, and people say all sorts of things, from hardware, to software and beyond.
I thought it might be related to the fact that my PC is attached via HDMI to a Samsung TV HD/4k (55"), but it seems to still happen on my 27" monitor, so I don't think the screen is the issue here. One of my running theories is that I perhaps attached incorrect wires from the PSU to my GPU, and it may not be getting enough power? I consider myself pretty computer savvy though, and I'm pretty sure I hooked it up correctly.
The 2080 Super has two, 8 pin connections. The modular power supply cords I am using are two, 6 pin connections with two, double pin "attachments" to each 6 pin connection (if this makes any sense).
Type4, PCle
connections.
Anyone with any insight to what might be causing my issue here? Even if it's just a theory, please let me know - I am desperate. Thanks people of Tom's!
Hey there,
The problem seems to be related to your PSU. Could you provide the exact model and its age? If you have another one available for testing, that would be the fastest option. If not, a friend could lend you one. Alternatively, take it to a nearby repair shop to swap and test it. Finally, once done, get a new PSU. Also, verify basic connections and ensure everything is properly plugged in. For modular units, replacing the cables might be necessary.

Thanks for the reply!
Everything is plugged in correctly to the best of my knowledge (unless I'm doing something wrong with my GPU power connection cables). I considered the PSU as well, but it is less than a year old. I believe it is a CX750W Bronze Corsair. I may just buy another considering it's about $100, but I'd prefer to not make the expense if there is another fix/issue causing this.
Yes, I see your point. No one wants to waste money. The CX isn't a terrible PSU, but not outstanding either. It's adequate for your setup, though I'd think about getting a gold unit instead. You might want to file a return or exchange, as it's still covered under warranty. Fingers crossed the replacement works out.
I've thought about sending a return request, but at this stage I might just settle for a Corsair 850W Gold and try to leave my problems behind. Spend a bit more on a whim, but I don't see anything else causing me trouble. I'm connected to a surge protector, though I'm not sure if that matters; I guess it would receive the same power from the wall. I found this discussion ( https://forums. ) and noticed most people blame the PSU. The thing is, I changed the PSU and other components last year for this same problem, but it's still happening now. Perhaps the PSU failed.
Well, if you're okay with that, it's one way to check and hopefully fix the problem. If you prefer Corsair, consider the RMX/RMI/TXM Golds—they're all decent. You might also check an EVGA G2/G3 or Seasonic Focus/Plus Gold.
I checked out the Seasonic's, but wasn't too confident about the build. I understand the Corsair RM lineup is reliable, so ordering one seems reasonable. I'm still weighing other options and hoping someone else has ideas or suggestions. Thanks for the input from your friend.
I attempted to clean it out, changed the thermal paste, and repositioned the cables, testing various ports on the power supply. Still no improvement. It appears my efforts made things worse. The computer is slowing down and can't run simple programs. A major issue.
