The Parisian club has now claimed the prestigious trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the French league champions and the Coupe de France holders after the French winger opened the net early on.
However, Marseille fired two times late to take a shock advantage. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned 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 moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past 13 years.
