The Parisian club has now secured the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful 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 between the French league champions and the French Cup holders after Ousmane Dembele found the scoring early on.
However, Marseille fired twice late to seize a shock advantage. First, the English forward converted 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 dying moments to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 penalty 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 lifted this competition for the 12th time in the past 13 years.
