The Parisian club has now claimed the prestigious cup on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the scoring in the opening stages.
Yet, Marseille fired two times late to take a shock lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to seal a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
