I am moving a Seagate 200 gig IDE HD to my new Insprion 530. I purchased the converter SW 1615 and now recognize that I need the power cable that I am going to purchase. The power cable utilizes the four-pin power connector SP4. The Inspiron 530 utilizes a flat multi point power plug does not match and as best as I can tell the Inspiron does not provide a four-pin power connector SP4. Is there an adapter available to mate the 4 pin to the flat multi point power plug? Or am I missing a possible power port on the Inspiron that would work

Thanks for any input
