PSG has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the net early on.
Yet, Marseille 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 remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 seasons.
