The Parisian club has now secured the season-opening trophy on 14 different times.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 champions and the Coupe de France winners after the French winger found the scoring early on.
However, the southern French side struck twice late to take a shock advantage. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to seal a convincing penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
