PSG has now secured the season-opening cup on fourteen different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
However, Marseille fired twice late to take a shock lead. Initially, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a crucial leveler in the final moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time winners PSG, who met 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 last thirteen years.
