Is it just a coincidence that the PC powers down unexpectedly?
I experienced this issue twice today... and I don’t have any leads or suggestions to help diagnose what’s going on. In fact, while using the computer for normal tasks like Minecraft, Twitch, Discord, and Steam, it just stopped unexpectedly. I checked the other devices in the room, and everything else was still powered on—except the internet router, which seemed to restart as though it had lost power for a brief moment. This happened twice, about an hour apart.
To explain my setup, I have the gaming PC and an air conditioner in the same space. A heavy-duty extension cord connects the PC to a server room where the router is located. Only the gaming PC is powered through this single circuit, while the monitors, AC unit, and router are all connected locally. Since the router and PC shut down simultaneously, they must be on separate circuits from the breaker. I’ve confirmed this by checking outlets in different rooms and noting which ones provided power.
When the PC stops working, the router restarts for about ten minutes each time. I’m not sure why this is happening. A friend suggests it might be a power problem with the breaker box, but I’m skeptical—how could that be if neither circuit lost power? Do you have any ideas on what I should try or test to figure this out?
The details about the PSU's make and model were not included.
Yes, that's accurate. But when two circuits operate at the same time? How often would it be possible to trigger two distinct circuits in identical, nearly simultaneous ways—just a brief moment of activation—repeated several times within a single day? No other equipment displayed any signs of instability, since the alarm clocks throughout the house stayed functional, unlike during a power outage, which would have affected the serverbox in the adjacent room (same circuit as the gaming PC that immediately powered down).
Everyone seems to think it's a power loss issue, but I'm wondering if it's actually external. It wouldn't be the same as the PC problems I experienced from December to February. Sorry if that made me doubt it. I really hope it's just that and I won't have to worry about the PC shutting down when I try to use it.
