PSG has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the showdown featuring the French league champions and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, the southern French side fired twice late to seize a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital leveler in the final moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to complete a convincing shootout victory.
Now 14-time winners PSG, 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 last thirteen years.
