The Parisian club has now secured the prestigious trophy on 14 separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the Ligue 1 winners and the French Cup holders after the French winger found the scoring early on.
Yet, Marseille struck two times late to seize a surprise advantage. Initially, 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 fortune, Goncalo Ramos grabbed a crucial leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
