The Parisian club has now secured the prestigious trophy on 14 separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the net early on.
Yet, Marseille struck two times late to take a shock lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last 13 years.
