PSG has now won the prestigious trophy on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side struck two times in the closing moments to take a shock advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the final moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a convincing penalty win.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last 13 seasons.
