The Parisian club has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown between the French league champions and the Coupe de France winners after the French winger found the net early on.
However, Marseille fired twice in the closing moments to seize a shock lead. Initially, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to seal a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
