The Parisian club has now secured the prestigious cup on 14 different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, the southern French side struck twice late to take a surprise advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a vital equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 seasons.
