I recently bought an IBUYPOWER prebuilt PC from Costco. It has impressive specs, including a 4070 Super GPU and an Intel i9-014F processor, along with a 2TB SSD. I usually play demanding games like Cyberpunk and Spider-Man at high settings, targeting 4K resolution with a locked 60fps, using DLSS and Vsync. Up until now, everything worked fine, but I've started experiencing random shutdowns while gaming. I've done some research and suspect that the power supply unit (PSU) might not be configured to single rail mode, though I haven't found instructions on how to check or change this. Also, I'm using a power cable plugged directly into the wall. Any advice?

Yeah, prebuilt systems often come with lower-end PSUs, so that's definitely a possibility. It could be shutting down due to inadequate power under load. You might want to investigate further or consider an upgrade if that's the case.
I had a similar problem with my 3080ti. It turned out to be plugged into a power strip with too many devices. Once I connected it directly to the wall, it stopped shutting down. It could be worth checking your setup to see if something similar is happening!
It sounds like it might be thermal shutdown or a power delivery issue. Keep an eye on your temps while gaming, and definitely check your PSU. Prebuilts sometimes skimp on the PSU quality, which could be your problem. If things don't improve, you might want to consider replacing it or getting some professional help.
I totally get that. I've seen similar issues in other threads that mention checking power supply settings, and it's usually just a the PSU that needs a better look.
