PSG has now won the season-opening cup on fourteen different occasions.
The Parisian giants required a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the net early on.
Yet, Marseille fired two times in the closing moments to seize a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 years.
