The Parisian club has now claimed the prestigious cup on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side struck two times late to seize a shock advantage. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to seal a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last 13 years.
