So im set to buy a Sapphire Radeon HD 6970 but it says that it needs at least a 500w psu. so i went to pcpartpicker and i mapped out my current build and if i put that gpu in, my total is 404w with keyboard and mouse and everything. I have a 430w psu. (yes i know its not that much) The question is do i need a 500w psu to run this card? or should i just go with the pcpartpicker that says i only need 404w to run the entire system?
