PSG has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired two times late to seize a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
