The Parisian club has now won the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match between the French league winners and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to seize a surprise lead. First, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the 12th time in the past thirteen seasons.
