[QUOTE="chscag, post: 1858350, member: 46727"] Can you hear the fan running in your iMac? Do you have an app that shows fan speed and temperatures? If you don't, my advice is to download and install one. Here's one that's free and will show the fan speed and temperature: [URL unfurl="true"]https://crystalidea.com/macs-fan-control[/URL] This will give you some idea if your iMac is overheating and shutting down or if it is in fact something wrong with the power supply. If the fan is not running in your machine, it will shut down. [/QUOTE]
