PSG has now claimed the season-opening trophy on 14 different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown between the French league champions and the Coupe de France holders after the French winger found the scoring early on.
Yet, the southern French side struck twice in the closing moments to take a shock advantage. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past 13 seasons.
