The power supply unit on my new iMac Pro is damaged and I cannot power the machine on anymore. I have two options: To get the iMac replaced by Apple since this machine is less than 2 weeks old To have it repaired by Apple authorised service provider with no guarantees that my data will remain intact. I have some files on this iMac that isn’t backed up anywhere else, and I really need to retreive them. Ideally, I’d retrieve my files and have the iMac replaced by Apple. Does anyone know if there’s any way I can achieve this?

You either need to remove the storage or replace the power supply (hoping thats all that needs replacing) I see no other way. This would void your warranty and you still need to buy a second system! Unlike the other iMac’s this system uses raw flash modules which are interleaved. In addition they can be encrypted! (depending on what you’ve selected) Removing the flash storage would require you placing them into another iMac Pro and even then they may not respond due to the encryption. There is no external case to support them. I think your only hope is to take it in to either an Apple Store or authorized Apple service center. Given the newness of the system I would go to the Apple Store (one that has the staff trained on servicing the system locally). Making sure they don’t swap your system on you is your only hope. In the end you’ll need to start backing up more frequently or setup a sync process copying over your work to iCloud or a local drive so you’re not caught off guard the next time.

Power supply can be replaced and data “should” still be there as you do not have to initialize anything for just that part swap. As you know only guarantee is YOUR backup.. HDDs for this model cannot just be swapped into another because of they have to be initialized with the system board they are installed in (just replaced a system board hoping the drives would come up but they come up blank and ask for system recovery)
