PSG has now claimed the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the match featuring the French league winners and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, Marseille fired two times late to take a surprise advantage. First, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the 12th time in the past 13 years.
