I have two ps4s in my household, both of them turned off by themselves at the same time. House power didn’t flicker or turn off. I thought it was very strange. They are plugged in separate rooms. Wondering if this has happened to anyone else. Maybe PlayStation network? Or maybe my house is haunted lol answers would be great so I stop freaking myself out lol
Power may not be stable in your house on that certain electrical circuit that both the ps4s are most likely plugged into. If the PS4 is still working consider getting an UPS (Uninterruptible Power Supply) which allows the console to stay on in the event of momentary power loss or even a blackout which will give enough time to turn the console off safely.
