The Parisian club has now claimed the season-opening cup on fourteen different occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the scoring early on.
However, Marseille fired twice late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital leveler in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past 13 years.
