PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match between the French league winners and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
However, Marseille struck two times in the closing moments to seize a surprise advantage. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker snatched a vital equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last 13 years.
