The Parisian club has now secured the season-opening trophy on fourteen different times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the match between the French league champions and the French Cup winners after the French winger opened the net in the opening stages.
However, the southern French side struck two times late to seize a surprise lead. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital equaliser in the final moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen years.
