The Parisian club has now won the prestigious trophy on 14 separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the showdown featuring the French league champions and the Coupe de France winners after the French winger found the scoring in the opening stages.
However, Marseille struck twice in the closing moments to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 shootout win.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past thirteen years.
