The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the French league champions and the French Cup winners after the French winger found the scoring early on.
However, Marseille fired two times in the closing moments to take a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
