PSG has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals 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 match featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the net in the opening stages.
However, Marseille struck two times late to take a shock advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to seal a convincing shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
