The Parisian club has now claimed the prestigious cup on 14 separate occasions.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the match between the Ligue 1 champions and the French Cup winners after the French winger opened the scoring early on.
Yet, Marseille fired twice late to seize a shock advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last thirteen years.
