PSG has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, 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 unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 seasons.
