PCI Express slots - can a card made for x1 to into a x8 or x16 slot?

The answer to that in the spirit of Joe L is "Maybe".

 

According to the PCI-e spec I believe it should work, but who knows if the spec was fully obeyed when it was designed, or if operation other than in an x1 slot was tested..

I don't like walking in water when I can't see the bottom. 

 

Oh well, I guess if I want to add esata ports I'll have to experiment some more.

Is the "it" the motherboard or the adapter card?  Is there any risk to the motherboard from plugging it in and seeing if it works?

The question is, will the motherboard support a mass storage controller in the x16 slot.

If the motherboard/bios support it, then chances of the x1 card working in the x16 slot are good.

It's usually a software support issue more then an electrical issue.

PCIe is supposed to be upwards compatible. x1 can go in x4, x8, x16.

As of late, a number of motherboards reserve the x16 slot for video.

 

So the answer is, contact your motherboard manufacture or test it.

 

FWIW, it works in my Abit AB9 PRO.

My unRAID box has two of these similar cards (mine don't have the external SATA connectors) but they have the same SIL3132 chipset:

One is installed in a 1x slot and the other is installed in a 16x slot on an Intel DQ965GF motherboard.  Both work well, so in my case, yes you can install a 1x card in a 16x slot.

Agreed.

 

I also have 3 of the aforementioned internal monoprice ones with the same chipset (sil3132) in my system. 1 in a x1 slot, 2 in x16 slots. 

 

mobo: Gigabyte GA-MA790GP-UD4H

 

They all work well. For the record, I ran them out of the box with the raid bios, and they worked fine (just got an error on boot saying raid wasn't enabled because only one drive on card). Have since flashed them all with the bios to make them into a regular sata controller.

Yea, it works in the x16 slot on my motherboard.  Now I have 2 esata ports and 2 internal ports that also work as esata ports in the x1 and x16 slots.  I unplugged my esata dock from one card and plugged into the other and it worked.  All hotpluggable.
