I want to know if my cooler master extreme power plus 550w is enough for a amd rx 470, I have read that the actual maximum power of that psu is 500w. My pc specs: motherboard msi gma p34 fx. Processor amd fx-4200 3.3ghz. I have one 120gb ssd and a 500gb hhd and two 12v fans. I don't have money for another psu, so if it doesn't work i will go for a rx 460 since it uses less wattage (Also i want to know if it will work too) Thanks.
