PSG has now claimed the season-opening trophy on fourteen different occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the net early on.
Yet, Marseille struck twice in the closing moments to take a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital equaliser in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last thirteen seasons.
