The Parisian club has now won the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive 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 winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side fired two times in the closing moments to seize a surprise advantage. First, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing shootout win.
The record champions 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 13 seasons.
