PSG has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be sailing towards a comfortable win in the match featuring the French league winners and the Coupe de France holders after the French winger opened the net in the opening stages.
Yet, Marseille struck twice late to seize a shock advantage. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker snatched a vital equaliser in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for PSG to seal a convincing penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last 13 seasons.
