PSG has now secured the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, Marseille fired twice in the closing moments to seize a shock lead. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past 13 seasons.
