The Parisian club has now won the prestigious trophy on 14 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 capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired twice late to seize a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately 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 send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 years.
