iMac is powering off for no reason

I have a 27" iMac that suddenly powers off for no reason. Tried a number of fixes, but it just seems to be occurring more often.

Do you already tried to reset the NVRAM: How to reset NVRAM on your Mac - Apple Support and the SMC: Reset the System Management Controller (SMC) on your Mac - Apple Support ?

In case of problem you can give a try with this and see if you have a known issue: https://etrecheck.com/ (you can post here the full report) and as last chance of course contact the Apple Support: Contact - Official Apple Support
