imac power keeps cutting out

I have an iMac retina 27" late 2015 that has recently started repeatedly cutting out. Just going blank as though someone has pulled the plug.

I replaced the power cord, thinking that was the problem, but it still keeps shutting down.

I've run an etrecheck and that has revealed no major problems. (Attached here.)

Any ideas?
