PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match featuring the French league winners and the French Cup winners after the French winger opened the net in the opening stages.
However, Marseille struck twice in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
