The Parisian club has now claimed the season-opening trophy on 14 separate times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the showdown between the French league winners and the French Cup holders after the French winger opened the net early on.
However, Marseille struck twice in the closing moments to take a shock advantage. 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 breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing penalty win.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 years.
