PSG has now secured the season-opening cup on 14 different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be sailing towards a comfortable triumph in the match between the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck two times late to seize a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past thirteen seasons.
