The Parisian club has now secured the prestigious trophy on 14 different occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the match featuring the French league winners and the French Cup holders after the French winger opened the net early on.
However, Marseille fired two times in the closing moments to take a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past thirteen years.
