PSG has now secured the prestigious trophy on 14 different times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the French Cup holders after the French winger found the net early on.
Yet, the southern French side struck two times in the closing moments to seize a surprise advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past 13 seasons.
