The Parisian club has now claimed the season-opening cup on fourteen different times.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a comfortable triumph in the match between the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
However, Marseille fired two times late to take a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
