PSG has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the French Cup holders after the French winger opened the net early on.
Yet, Marseille struck two times in the closing moments to take a surprise lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen years.
