PSG has now won the prestigious cup on 14 different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the net early on.
However, the southern French side struck twice in the closing moments to seize a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen years.
