The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a straightforward win in the showdown between the French league winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 seasons.
