PSG has now claimed the season-opening cup on 14 separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown between the Ligue 1 champions and the French Cup winners after the French winger opened the net early on.
However, the southern French side fired two times in the closing moments to seize a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing shootout victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen years.
