PSG has now won the prestigious trophy on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to take a shock advantage. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 years.
