PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the match between the French league winners and the French Cup winners after the French winger opened the net in the opening stages.
However, Marseille fired twice in the closing moments to take a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial leveler in the final moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen years.
