The Parisian club has now won the prestigious cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the French league champions and the French Cup winners after the French winger opened the net early on.
Yet, Marseille fired two times in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a crucial equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past thirteen years.
