The Parisian club has now won the prestigious cup on 14 different times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match between the French league winners and the Coupe de France winners after the French winger found the scoring early on.
Yet, Marseille fired twice late to take a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho 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 send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past 13 years.
