PSG has now won the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net early on.
However, the southern French side fired twice late to take a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for PSG to complete a convincing shootout victory.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last thirteen seasons.
