The Parisian club has now secured the prestigious trophy on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele found the net early on.
However, the southern French side fired twice in the closing moments to seize a shock advantage. Initially, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 penalty victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last thirteen years.
