PSG has now claimed the prestigious trophy on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the match between the French league winners and the Coupe de France holders after the French winger opened the scoring early on.
Yet, Marseille fired two times late to seize a shock advantage. Initially, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last 13 seasons.
