PSG has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille fired two times in the closing moments to take a surprise lead. First, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the final moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to seal a convincing penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
