so i bought a 500W power supply, put it in, works fine, bought a i7-6700 put it in, works fine, tried to put in my rx580 bumblebee and it fits but whenever i launch a game my monitor go black and the pc resets itself, am i doing something wrong? or does the gpu just draw too much power and 2nd question would a 1660 super 6GB be good for my build

idk what else to say, they're just so bothersome and in the way, i also developed some little "sparkly" (sometimes blue) things in my vision and i don't have healthcare and everything i look up is just like "as long as there isn't a shower of floaters, no curtains in your vision and no flashes of light then you're good!" i wonder how much of this is just me overthinking or overanalyzing vs it being something
