The Parisian club has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck twice in the closing moments to seize a surprise lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to seal a convincing 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 twelfth time in the past 13 years.
