I had one system sitting idle powered on and plugged another system into the surge protector strip with its PSU off (O position), this caused a tiny spark at the plug/outlet, I've seen this before plugging in my router since it has no power switch and thought nothing of it, but noticed it had caused the system that was powered on to have a hard shutdown.
Why did this happen? Could this have caused any damage? I'm getting conflicting answers trying to Google it, anyone have any ideas?
