The Parisian club has now secured the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward win in the showdown between the French league champions and the French Cup holders after Ousmane Dembele opened the scoring early on.
However, the southern French side fired two times in the closing moments to seize a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital leveler in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
