The Parisian club has now won the prestigious trophy on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the match between the French league winners and the French Cup winners after the French winger found the net early on.
Yet, the southern French side fired two times late to take a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, 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 Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
