The Parisian club has now won the prestigious cup on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown between the Ligue 1 winners and the French Cup winners after the French winger opened the scoring early on.
However, the southern French side fired two times in the closing moments to seize a surprise lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the final moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
