thanks for the replies
Actually the VPU and NB are on there seperate line and CPU on another
but
Since Im not doing volt mods ( dont plan on im a wimp lol ) then 80 shall be fine. It will be hooking up to Vantec Stealth 420 watt so that would be just fine. and MAYBE is I have the extra $$ Ill go for that higher wattage, but this 80watt should get me into the subzeros at idle hopefully?
