Edzuan was later named the player of the tournament in the university category.
PMM had lost the final to PSA in 2010 and to Universiti Putra Malaysia (UPM), who are the rugby sports excellence centre for Malaysian universities, in 2011 and last year.
PMM coach Mohd Shafie Osman said he was delighted to recapture the title amidst a much stronger field this year.
In line with a major re-branding effort this year, tournament co-organisers Polytechnic Sports Council (PSC) and PSA, increased the total prize purse from RM6,000 in previous editions to RM21,000.
"The boys really deserved this victory as their team spirit and absolute desire to be the best was what pulled them through two tough days of competition," said Mohd Shafie.
"PSA are our traditional rivals and as any game against them, the final was a very tense affair. Both sides were very cautious but we were given an opportunity to score and we did not waste that chance.
"To win it this year really means a lot to us, especially as the quality of the tournament increased a lot this year and also the fact that we had lost three finals."
Mohd Shafie added that he hoped the all-polytechnic final was a sign of good things to come for polytechnics in the sport.
"We hope to see the level of polytechnic rugby continue to increase in the future in line with that of universities such as Universiti Teknologi Mara and UPM.
"We are working towards having a polytechnic side compete in the Malaysian Rugby Union Super League in the future. Hopefully we will be able to make it a reality."
Meanwhile, the club category saw Shah Alam City Council (MBSA) beat Negri Sembilan Wanderers 31-0 in the decider while SM Sains Selangor clinched the school category title with a surprise 8-0 win over Tunku Mahkota Ismail Sports School SSTMI.
MBSA, PMM and SMSS received RM3,500, RM2,500 and RM1,500 respectively for their victories.
