The Parisian club has now claimed the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring early on.
However, Marseille struck two times late to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital equaliser in the dying moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past 13 seasons.
