The Parisian club has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the French league champions and the French Cup holders after the French winger opened the net early on.
Yet, the southern French side fired twice in the closing moments to take a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last thirteen years.
