The Parisian club has now secured the season-opening trophy on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
However, the southern French side struck twice late to take a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial leveler in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last 13 years.
