The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants needed 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 victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the net early on.
However, Marseille fired twice late to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing shootout win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last 13 seasons.
