PSG has now claimed the season-opening trophy on fourteen separate times.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring early on.
Yet, Marseille fired two times late to seize a shock lead. Initially, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital leveler in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 penalty victory.
The record champions 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 12th time in the past 13 years.
