PSG has now secured the prestigious cup on 14 different occasions.
The Parisian giants required a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the French Cup holders after the French winger opened the scoring early on.
However, the southern French side fired two times in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last thirteen seasons.
