The Parisian club has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the French league champions and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side fired two times in the closing moments to seize a surprise lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
