The Parisian club has now won the season-opening trophy on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the match between the Ligue 1 winners and the Coupe de France holders after the French winger found the net early on.
Yet, Marseille struck twice late to seize a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to complete a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen years.
