PSG has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward triumph in the match between the French league winners and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, the southern French side struck twice late to take a shock lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen seasons.
