Enough power for HD 6850 with i3 2100

[m-mag]

Hello,

This is a new built but I thought it'd be more appropriate to post this here. I will be getting the HD 6850, I hope, yet I have tight budget. So, I don't want to buy a very expensive PSU (or case +-PSU).

Here's my question: How many watts should be enough to run the HD 6850 with the i3 2100 (and a 500GB WDC blue).

Thanks!

You can easily run that off a quality 400w PSU, and CF with 550.

Antec Earth watts 430 is a decent PSU that comes included in a lot of cases. Be particular about brands, especially in the low end.
