The Parisian club has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match between the French league winners and the Coupe de France winners after Ousmane Dembele found the net early on.
Yet, the southern French side fired twice late to take a shock advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a vital equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a convincing penalty victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past 13 years.
