PSG has now claimed the season-opening cup on fourteen different times.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the scoring in the opening stages.
However, Marseille struck two times late to take a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a convincing shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 years.
