The Parisian club has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck twice in the closing moments to take a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a vital equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
