The Parisian club has now won the prestigious cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side struck two times in the closing moments to take a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker snatched a vital equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
