PSG has now secured the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired two times late to take a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced 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 twelfth time in the past 13 years.
