Coolmax is junk. So even if it did have enough 12v amps listed I would not trust it to actually be able to deliver what it's rated at. You are correct in that it says it can supply 35 amps on the 12v rail making it a 450w power supply. At least that's how a quality power supply would be labeled.
So no don't try it. Get a quality unit from Corsair, Seasonic, PC Power and Cooling, XFX, Silvestone, Enermax, OCZ, Antec or Rosewill.
Thank you very much for your response.
