4 lane PCI-e and PCI-e 16x

Hi

I have a spare Adaptec RAID controller card that I'd like to use in a normal desktop. The RAID controller card needs a 4 lane PCI-e slot, but the motherboard of the desktop only has two normal PCI-e 16x slots normally used for graphic cards. I was told that it will work if I put it into the normal PCI-e 16x slot on the motherboard, but I'd like to confirm that. Those RAID controller cards are too expensive to take a chance ;-)

The motherboard in question:  Intel X58 "Smack Over"
The RAID controller: Adaptec RAID 3405

I'd appreciate it if someone could confirm this for me.

Thanks

Just to clarify ...

A PCIe x1 card can be installed in an x1, x4, x8, or x16 slot
A PCIe x4 card can be installed in an x4, x8, or x16 slot
A PCIe x8 card can be installed in an x8 or x16 slot
A PCIe x16 card requires an x16 slot.

Yes, it will work fine.    You can put any PCIe card in a PCIe slot that has as many or more lanes than it requires.
