So this morning a circuit in my house blew because too many things were running at once. My brand new iMac 5K, in Sleep mode, was plugged into a Surge Protector which was plugged into my wall, so that means it had to unexpectedly power off. I reset the circuit, powered up my iMac, and all seems fine. I checked Disk Utility and everything seems fine after running First Aid. My question, though, is... How can I be sure that everything is okay and nothing was harmed? I'm a little paranoid, and this machine is brand new and maxed out, I just hope there's nothing wrong that I don't know about.
