PSG has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider 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 match featuring the Ligue 1 champions and the Coupe de France holders after the French winger found the scoring early on.
Yet, the southern French side fired twice late to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial attempts 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 seal a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
