The Parisian club has now won the prestigious trophy on 14 separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward win in the showdown featuring the Ligue 1 winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, the southern French side struck twice in the closing moments to seize a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial leveler in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past 13 years.
