I encountered a similar issue before and discovered it was related to the PSU. I recently swapped out a faulty unit for a better one, which received excellent reviews. Everything worked smoothly until recently... Today, during an event in our neighborhood’s energy grid, the neutral cable powering the transformer failed. All surge protectors in the building malfunctioned, and the power became unstable. This also affected my neighbors. My PC was off but connected via a surge connector with a switch, plugged into the main outlet—well-designed wiring and proper grounding were present. When I arrived at my office, the air smelled bad, and the surge protector exploded. I cut the power until the issue was fixed on the street. Everything seemed normal until I tried using another simpler surge protector; it shut down immediately. I attempted to resolve it by changing its fuse, which restored functionality. Now, when I play games with default GPU settings, my PC crashes after about 30 minutes. The fuse likely failed again. I’ve connected the PC directly to the wall and am documenting this. I haven’t reintroduced power-hungry tasks, fearing damage. If this pattern repeats, I’m concerned about the surge protector fuses blowing repeatedly. I assumed fuses only fail when high voltage enters from the grid, but I never realized a device could be damaged by internal surges. Could someone explain if there’s another issue in my building’s power circuit causing these problems with my PSUs? Why are my PSUs and PCs repeatedly blowing these fuses?"

It's likely the basic surge protector you used isn't strong enough for your PC's needs, leading to shutdowns. Invest in a better one to avoid similar issues.

Yes, we can determine it by considering the power usage of the PSU when operating and using its fuse details.
