Just got my cables in and installed them, however I don't know if this is an RMA detail or by desing. My 24 pin connector is missing a connector on the 18 pin power supply connection. I do have a 550GS so it might be incompatible although all other cables work. Here are 2 pic to show,

If these are wrong can someone direct me to how to RMA these, they don't have a serial number to add to my EVGA products List.
