The Parisian club has now claimed the season-opening cup on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable triumph in the match between the French league winners and the French Cup holders after Ousmane Dembele opened the net early on.
Yet, Marseille fired two times in the closing moments to take a surprise lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital leveler in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past 13 years.
