I have a 550w power supply can i run a core i7?

Hello,
just wondering if anybody can help me, i bought a core i7 today thinking that my 550w psu would run it but i started getting the blinks, power on power off continuously while trying to load. i have a gigabyte P67A-GD55 mobo and 2x 4g corsair ram and an nvidia gts450 graphics card and operating windows 7 x86 . the psu isnt a known brand and it says maximum power output is 550w....
is this my problem? not enough juice? i have searched evrywhere about this.
hope someone can help me, please

  1. It's a good idea to run a psu that supplies 500 continuous watts for your gpu and specs.
  2. Read this:

    how many 12V amps/watts does it say you can use?
  3. If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.
