PSG has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the match between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, the southern French side struck twice in the closing moments to seize a surprise lead. First, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners Paris Saint-Germain, who faced 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 seasons.
