Yes, your prcoessor will only use 166.4W; the motherboard, cpu cooler, hdd and ram use next to no power - so yes it will work. You haven't mentioned the gpu so I don't know how much power that will draw. If you don't have a gpu, yes you will be able to overclock the cpu pretty easily considering your psu is an 80 certified plus or something to that effect.

Hope this helps!

In a really short answer... you'd be lucky. If you want to overclock, get something a little more substantial. Hope this helps!

Do the math
229 w load
85% efficient psu http://www.plugloadsolutions.com/psu_reports/PC%20POWER...
~ 195 watt load

Add the maxpower rating of the 6670 , 66w

261 watts, not quite 60% ( didn't feel like doing more math ) of the psu's capacity
You decide
