PSG has now secured the season-opening cup on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and secure 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 Ligue 1 champions and the French Cup holders after the French winger found the net early on.
Yet, Marseille fired twice in the closing moments to seize a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital leveler in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the last thirteen seasons.
