The Parisian club has now won the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the showdown between the French league champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck twice in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last thirteen years.
