The Parisian club has now won the prestigious trophy on 14 different occasions.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable win in the match featuring the French league champions and the Coupe de France holders after the French winger found the scoring early on.
Yet, the southern French side struck 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 turn of events, Goncalo Ramos snatched a vital equaliser in the dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the 12th time in the last 13 years.
