PSG has now claimed the season-opening cup on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the French league champions and the Coupe de France holders after the French winger opened the net early on.
Yet, Marseille fired twice in the closing moments to seize a surprise lead. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing penalty win.
The record winners PSG, who met 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 last 13 years.
