PSG has now secured the season-opening trophy on fourteen 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 European champions appeared to be coasting towards a straightforward win in the match between the Ligue 1 champions and the French Cup holders after the French winger opened the scoring in the opening stages.
However, Marseille struck two times late to seize a surprise lead. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the match into a penalty 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, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
