The Parisian club has now secured the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward win in the match featuring the French league winners and the French Cup winners after the French winger opened the scoring early on.
Yet, Marseille fired twice late to seize a shock advantage. First, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 seasons.
