PSG has now won the season-opening trophy on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the scoring early on.
Yet, Marseille struck two times late to seize a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 seasons.
