The Parisian club has now claimed the prestigious trophy on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the French league winners and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
