The Parisian club has now secured the prestigious cup on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown between the French league winners and the Coupe de France holders after the French winger found the net early on.
However, Marseille struck two times late to seize a surprise lead. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen years.
