PSG has now claimed the prestigious trophy on fourteen different times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the match between the French league champions and the French Cup holders after the French winger opened the scoring in the opening stages.
Yet, Marseille struck two times late to seize a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos snatched a crucial leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past 13 seasons.
