PSG has now won the prestigious cup on 14 separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times late to seize a shock advantage. Initially, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last thirteen years.
