PSG has now secured the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the French league champions and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, Marseille struck 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 twist of fortune, Goncalo Ramos snatched a vital equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to complete a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the 12th time in the last thirteen years.
