Hi I have a similar Issue, I'm in the UK so don’t think its a grounding issue… Randomly turns off sometimes as soon as trying to log in, some times 40 minutes after logging in, other times 24 hours. It is not a complete shut down it is just completely losing power. I have an iMac (Retina 5K, 27-inch, Mid 2015) and just wondering for any advise out there?

I’ve looked at the process into replacing the power supply unit - the issue is I have a small crack in the glass on the screen - luckily this hasn’t effected the display…. Is this likely to break or damage further taking this to pieces?

Any help would be greatly appreciated.
