The Parisian club has now claimed the season-opening cup on 14 different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the French Cup holders after the French winger found the net early on.
Yet, Marseille struck two times late to take a shock advantage. First, Mason Greenwood 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 fortune, Goncalo Ramos snatched a vital equaliser in the dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions 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 twelfth time in the past 13 years.
