PSG has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a straightforward win in the showdown featuring the French league champions and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille fired twice late to take a shock advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete 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 achieving a league and cup double, have now lifted this competition for the 12th time in the past 13 seasons.
