The Parisian club has now won the prestigious cup on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful 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 straightforward triumph in the showdown between the French league winners and the French Cup holders after the French winger found the net in the opening stages.
Yet, Marseille struck twice late to seize a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently 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 seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing penalty victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
