The Parisian club has now claimed the season-opening trophy on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, Marseille struck twice in the closing moments to seize a surprise advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
