  1. 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!
  2. Yeah sorry forgot about the GPU. Its a Radeon 6670 Crossfired with the A8-3870K
  3. In a really short answer... you'd be lucky. If you want to overclock, get something a little more substantial. Hope this helps!
  4. Even shorter answer, yes
  5. Hmm mixed results : / So do i need to up my power supply? Overclocking from 3.0ghz to only 3.5 - 4.0 if it allows

    Do the math
    229 w load
    85% efficient psu http://www.plugloadsolutions.com/psu_reports/PC%20POWER%20&%20COOLING_SILENCER%20750%20EPS12V_ECOS%201449_750W_Report.pdf
    ~ 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
