PSG has now claimed the prestigious trophy on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable triumph in the showdown between the Ligue 1 champions and the Coupe de France winners after the French winger found the net early on.
However, Marseille fired twice in the closing moments to take a surprise lead. First, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial leveler in the dying moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time winners PSG, who faced 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 last 13 seasons.
