The Parisian club has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side fired twice in the closing moments to seize a shock lead. Initially, the English forward converted 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, the Portuguese striker snatched a vital equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
