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.
 
Run the Apple hardware test (press and hold d whilst powering on till you see a grey screen)
 
Reset the circuit, power it up, and see if it seems fine. If you're inclined, you can open Disk Utility and run first First Aid on the disk.
 
I suspect the surge protector saved your iMac. There is a setting on the imac to not restart after power failure - I always set it.. then press the start button after things calm down.

Yeah I have it set that way too.
