The 2004 edition of the postseason tournament started on September 8, 2004 and ended on September 22, 2004, with the Philippine Christian University (PCU) Dolphins winning their first NCAA Basketball championship at the expense of the University of Perpetual Help Dalta System (UPHDS) Altas. PCU's Robert Sanz was adjudged as the Finals MVP.
At end of the elimination round, the PCU Dolphins and the UPHDS Altas emerged at the top of the standings with identical 10-4 cards. The UPHDS Altas got the first seed by virtue of having a better points difference (UPHDS won the first game by 13 points, while PCU won the second game by nine points). Defending champions Letran Knights followed at third. Three teams were tied for the last Semi-Final berth. UPHDS, PCU and Letran received automatic semi-final berths.
