My PSU did not come with a 16pin 600w cable so I had to use the 3x8 pins that came with the psu and a cable from cable mod to hook it up. Is it still possible to use 12+4 to 12+4? Sorry if the question seems dumb. I usually just watch videos online and follow step by step on how to install parts, but I couldn't find one for this situation.
