The Parisian club has now won the season-opening cup on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a straightforward win in the match featuring the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring in the opening stages.
However, Marseille fired twice in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the 12th time in the past 13 years.
