PSG has now claimed the season-opening cup on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side struck two times late to seize a shock lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 penalty victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last thirteen years.
