The Parisian club has now secured the prestigious cup on fourteen different times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the match featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, the southern French side struck two times in the closing moments to seize a shock lead. First, the English forward scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the last 13 years.
