The Parisian club has now secured the season-opening cup on fourteen different times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the net early on.
Yet, Marseille fired two times in the closing moments to take a shock lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
