PSG has now claimed the prestigious trophy on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired twice late to take a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, 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 past thirteen years.
