Oh man that is bad I wanted to either not connect a 8pin cable at all since a very similar platform on the AM1 series doesn't need or come with one or use one of my adapters that combines a 4PIN CPU cable and a molex cable which has worked fine on my H8SCM with the same CPU before I got a new PSU for it (H8SCM only $40 - I don't want to risk this $300 brand new KCMA-D8 although they are going for only $90 china used on fleabay atm) > Never use these unless you know they can take the > current you expect!
