A:Answer This is used for only a regular PCI Slot x1, x4, x8, x16, I don't see how this can fit into a "MINI" PCI slot. It is meant for an empty bay on a Desktop PC, also needs power, make sure you have an extra 4 pin power supply. Your main Power Supply is okay as this will not over power it, it uses very little power, unless you feel you are maxed out by your main PSU.
