The Parisian club has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup winners after the French winger found the net in the opening stages.
Yet, Marseille fired twice late to seize a surprise advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a convincing penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 years.
