I have an old r9 270 which i always ran overclocked to 1050/1500 basically making it identical with r9 270X. Without the overclock it says it uses 150W of power. So overclocked it must be alittle bit more. I have a 500w bronze 80+ rated psu. I bought a used gtx 1060 6gb windforce OCand want to swap with the 270 but i dont know if the psu will be enough. I mean it says 120W its 30less. Im planing to buy a new psu soon bvut in the meantime will the psu be enough?
