The Parisian club has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup winners after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times late to take a shock lead. Initially, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial equaliser in the final moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to seal a convincing penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
