PSG has now secured the season-opening trophy on 14 different times.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals 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 French league champions and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, Marseille fired twice in the closing moments to take a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
