The Parisian club has now secured the season-opening trophy on 14 separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side fired twice late to seize a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a convincing penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past thirteen years.
