The Parisian club has now claimed the prestigious cup on 14 separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side struck twice late to take a shock 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 remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
