PSG has now won the prestigious cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the Ligue 1 winners and the French Cup winners after the French winger opened the net early on.
Yet, Marseille struck twice late to seize a surprise advantage. First, the English forward 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 fortune, Goncalo Ramos snatched a vital equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 seasons.
