PSG has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable triumph in the match between the French league champions and the Coupe de France winners after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times in the closing moments to take a surprise lead. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a vital leveler in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
