PSG has now won the season-opening cup on fourteen different times.
Paris Saint-Germain needed a dramatic 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 Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup winners after the French winger opened the net early on.
However, Marseille fired two times in the closing moments to seize a surprise advantage. First, the English forward scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last 13 seasons.
