GTX-1060, due to the interval-like offloading of gpu-related work will
possibly generate some really nasty load-changes the power supply can't
cope with. It is well known that fast load changes of modern graphics
cards may overstrain the power supply unit if not "strong" enough.

The symptoms very much suggest a problem with the PSU. Maybe
Szilard Páll can comment on this.
