I think you can have problems today if you have a power failure mid motherboard firmware/BIOS/UEFI upgrade. Some mobos I heard have some protection or some way to unbrick it but it could be dangerous. And it was a real danger before for the running sofware system, I think modern filesystems are more resilient against this sort of problem. Never heard of actual physical damage though, but I didn't live that era much, can just barely remember the screen in TFA.
