The Parisian club has now claimed the prestigious cup on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last 13 years.
