PSG has now won the season-opening trophy on 14 different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the match featuring the French league winners and the French Cup winners after the French winger opened the net early on.
Yet, the southern French side struck two times in the closing moments to take a surprise advantage. First, the English forward scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing shootout win.
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 lifted this competition for the twelfth time in the last 13 seasons.
