The Parisian club has now secured the season-opening trophy on fourteen different times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward win in the match between the French league champions and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, Marseille fired twice in the closing moments to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the past thirteen years.
