So, I upgraded my psu and I notice that I need a 4 pin cable for my CPU, but my psu's cpu cable is 8 pin and won't split in half. Some people say I should just plug in the half that fits and never mind the other half. I'm not sure if I should do it. (correct me if I'm wrong I'm new to building/upgrading pcs)
