The Parisian club has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders appeared to be coasting towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck twice late to take a shock lead. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
