The Parisian club has now won the season-opening cup on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the French league champions and the Coupe de France holders after the French winger opened the net early on.
However, Marseille struck two times late to take a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last 13 years.
