The Parisian club has now secured the season-opening cup on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league winners and the French Cup holders after the French winger opened the scoring early on.
Yet, Marseille struck two times in the closing moments to seize a shock lead. First, 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 turn of fortune, the Portuguese striker snatched a crucial leveler in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
Now 14-time winners 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 competition for the twelfth time in the last 13 years.
