Edited: Got a rx 590 fatboy what watt power supply should i get. Ive been having issues it will run great then out of no where it crashes screen goes black then my monitor doesnt detect any input so i have to power cycle my pc and its back and working. Radeon settings says wattman is reset after it comes back on... im currently running 500w power supply, im thinking i need a better psu or is it another problem? 
Any help is appreciated
