PSG has now won the prestigious trophy on 14 separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown between the French league champions and the French Cup winners after Ousmane Dembele opened the net early on.
However, the southern French side struck twice late to take a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial leveler in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the last thirteen seasons.
