The Parisian club has now secured the season-opening trophy on 14 different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match 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 fired two times late to take a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
