PSG has now claimed the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the match between the French league champions and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, the southern French side struck twice late to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
