PSG has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match between the French league champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side struck two times late to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
