GamerSaxl :
should I buy an evga 500w 80+ certified? or is there literally any possible way to hook up my gpu to psu?
Don't go cheap on your PSU, most of the cheap brands can't deliver their rated power (see
HERE) and if they fail, they have the potential to damage all your other components. Yes there are ways to get another 6 pin, such as a molex to 6 pin adaptor, but these are only recommended for better PSUs that for what ever reason don't have enough 6 pin connectors.
The EVGA 500 80+ is about the cheapest PSU I'd be somewhat comfortable using, preferably look for the EVGA 500B 80+ Bronze as it's better quality.
