PSG has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the match between the French league winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, Marseille fired twice in the closing moments to take a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last 13 years.
