The Parisian club has now claimed the season-opening cup on 14 separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the match between the French league champions and the French Cup winners after the French winger opened the net in the opening stages.
Yet, Marseille fired twice in the closing moments to take a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last thirteen seasons.
