PSG has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain needed 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 Champions League holders seemed to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the French Cup holders after the French winger found the net in the opening stages.
Yet, the southern French side fired two times late to seize a surprise advantage. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
