PSG has now secured the season-opening cup on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown featuring the French league winners and the French Cup holders after the French winger found the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to seize a shock advantage. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the final seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last thirteen seasons.
