Hi, my build is just few months old. Last night while gameing (Cyberpunk) after 3h, PC just turned off. I tried to power it on, but nothing, like it was dead. This morning i tried, and it went on. PSU is my frst pick and it stil is, but it's just few months old and it's 1200w platinum by BeQuiet. Overheating problem? I have 3x140mm intake fans and airflow case (H7). CPU cooler is Noctua nh d15. Case fans (one of thame) makes strange noise at low speed. Fans are BeQuiet Silent Wings 4 High speed. If it's MBO it would not run after few hours. Right? What can i do now to detect the problem? Any advice? RAM is 2x16 GGPU is 7900XTX MBO is B550 Rog gaming CPU is 5800X3D (undervolted) Also i use costum cables for PSU, but they are the same brand as my PSU and they match PSU type.

I'm concerned you might have chosen an excessively powerful power supply for this setup, which wouldn't really require more than 750W. With custom cables possibly involved, there could be an issue with them. Would you try using the standard cables to rule out that problem? In the unlikely event your issue lies elsewhere, it might be due to the CPU overheating, GPU overheating, or another component failing—sometimes the NVMe drive can overheat and cause a system crash. The power supply itself could also be defective. Once you identify the cause, good news is your parts usually come with warranties. You can reach out to the manufacturer of the faulty component for a replacement. If overheating is the main concern, a fresh application of thermal paste and checking airflow inside the case should help. You might also consider sharing photos of your PC; they could provide useful hints about what's going on.

I keep using my PC normally until it stops after a few hours in Cyberpunk. After enabling the metrics, at full CPU fan speed, high CPU fan speed, and moderate GPU fan speed, temperatures reached 57°C for the CPU and 61°C for the GPU. Can I exclude overheating? It feels like the system is completely dead. This has never happened before. Probably related to the power supply unit.
