The Parisian club has now claimed the prestigious cup on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a successful 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 showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck twice late to take a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
