I have an Intel RES2SV240 on it's way to be to paired up with an LSI 9300-8i. The Intel RES2SV240's manual states it can be powered by PCIe x4 or Molex. I don't have a free PCIe x4 slot, but I do have a PCIe x1 Slot with a x16 connector that I will never use. Since it will fit and look clean, can I use this slot AND provide power via Molex?
