Im planning to upgrade my gpu but im worried that my psu isnt compatible. I have a 500w Cybertron psu and it only has one 6 pin pcie power connector. So I was wondering if I just purchased a molex to 8 pin connector if it would work correctly without harming any of my components. I have a amd 970A Krait Edition mobo. Thanks! And yes I do realize that a new psu is the best option but im on a budget and would like to go with the cheapest way possible, thanks again...
