PSG has now claimed the season-opening cup on fourteen different occasions.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the Coupe de France winners after the French winger found the net in the opening stages.
However, the southern French side fired twice late to seize a surprise advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital leveler in the dying moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the last 13 years.
