The Parisian club has now secured the prestigious cup on 14 separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side struck twice late to take a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
