PSG has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the showdown between the French league winners and the French Cup holders after the French winger opened the scoring early on.
Yet, Marseille fired twice late to seize a shock advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a vital equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past thirteen years.
