The Parisian club has now claimed the season-opening trophy on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the French Cup holders after the French winger opened the scoring early on.
However, the southern French side struck two times late to seize a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from 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 penalty 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 won this competition for the twelfth time in the last thirteen years.
