PSG has now claimed the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
However, the southern French side fired twice in the closing moments to seize a surprise lead. First, 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 remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to seal a convincing shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the last 13 years.
