The Parisian club has now claimed the prestigious cup on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the match between the French league champions and the French Cup holders after Ousmane Dembele opened the scoring early on.
However, the southern French side struck twice late to seize a shock 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 breathtaking twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial 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 complete a 4-1 penalty win.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past thirteen years.
