PSG has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown between the French league champions and the Coupe de France holders after the French winger opened the net in the opening stages.
However, the southern French side struck twice in the closing moments to seize a shock lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last 13 years.
