The Parisian club has now secured the prestigious trophy on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a straightforward triumph in the match between the Ligue 1 champions and the Coupe de France winners after the French winger found the scoring early on.
Yet, the southern French side struck twice in the closing moments to seize a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen seasons.
