The Parisian club has now claimed the prestigious cup on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable triumph in the showdown featuring the French league champions and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, Marseille struck two times in the closing moments to take a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 seasons.
