Ati 4770

a 450 should be fine for a 4770, if you could possible put up a link if you know that model, I could tell you with more certainty

thanks for answer. i dont know the model.

your system is great.

If you have at least 25A on the 12V rails than you are good. The Amps are written on a sticker on the PSU.

450W is just enough to run 4770...
About your PSU, what brand? model?

I run an OCZ psu with my 4770 and a quad core

never skips a beat very nice psu


so If you decide to upgrade I reccomend this

The 4770 is borderline as far as needing a power cable anyway. I would say that as long as your PSU has a dedicated PCIE plug, not one you made up from a converter then you are fine.

If the PSU is a Chokemax, it will blow if loaded to 75% of its label (in this case 337.5W). OTOH, a quality PSU like a 380W Antec Earthwatts would have no trouble at all. So, it would indeed help to know the brand and model of your PSU.
