Is it enough?

I don`t know anything about Power Supply and i want to know will my 450W Frontier PSU be enough for my system?
I`ll buy new card next month something like HD5750 or GTS 450.
Rest of my PC is:
Intel Pentium Dual Core E5300 2,6 GHz
Gigabyte G31M-ES2L motherboard
320 GB Hitachi 7.200 RPM
some LG DVD-RW.
So will I be able to run HD 5750 or GTS 450 with these specs with my current PSU, and what happens if the PSU can`t handle system?

More about enough
  1. I don't know anything about your Frontier psu. However, a 450W psu should be capable of powering 5750/450.
  2. It should be ok but you never can tell. If the power supply is not large enough the symptoms are the computer shuts off unexpectedly when booting up or when displaying 3D graphics requiring you to pull the mains power to reset the power supply to enable you to power up the computer again, or you may not even be able to power on at all.
  3. If you OC your card it will use more power, right?
    Will I be able to OC my card?
  4. We have no idea whether your psu will support the card. We can only tell you that a 450W, of unknown spec, if its any good, should do it.

    Buy the card, run it, and overclock slowly. If/when it fails, do not be surprised if you need a different psu.
