The Parisian club has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France winners after the French winger opened the net in the opening stages.
However, Marseille struck twice late to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past thirteen years.
