PSG has now secured the season-opening trophy on fourteen different times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, Marseille struck two times late to seize a shock advantage. First, the English forward converted from the penalty spot, 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 force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen seasons.
