PSG has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown featuring the French league winners and the French Cup holders after the French winger opened the scoring in the opening stages.
However, the southern French side struck twice in the closing moments to take a surprise advantage. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 seasons.
