The Parisian club has now won the season-opening cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the French league winners and the French Cup winners after the French winger opened the net early on.
However, Marseille fired twice in the closing moments to seize a surprise lead. Initially, Mason Greenwood converted 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, Goncalo Ramos grabbed a crucial equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a convincing penalty win.
The record champions 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 past 13 years.
