Buying Supermicro AOC-USAS2-L8i

Featured Replies

Anybody have any recomendations on the best place to purchase this item?

Promicro has the best price... $117 at the moment.  Sometimes you can find a coupon too.

 

 

Don't forget that it is UIO just in case you were not aware.

 

... but works perfectly well in a standard PCIe x8 slot, and is fully compatible with unRAID v5.0beta.  If you want to screw the board in, you will need to swap the backplate, or use spacers on the supplied backplate.

The card may work well if it fits in the connector but that they will fit in any x8/x16 PCIe connectors is a bold statement to make.

 

The pure x8 PCIe is rarely present on the motherboards and in most of the cases the motherboard MFRs will use a x16 physical connectors.

 

If your motherboard has a single x16 PCIe connector then is is designed to provide up to 75W to the cards. On the other hand a x4/x8 connector has to provide only up to 25W to the cards - you have different power requirements and thus a chance to have big and bulky capacitors very close to the other "wrong" side of the PCIe connector that will stand in the way of the UIO cards.

 

Since you have the card I will suggest for you to take a nice frontal picture with a ruler beside as to give an idea to the potential buyers if this card can fit in their motherboards.

I'm sorry, I hadn't considered that this would be quite such a difficult issue ... thank you for pointing out the problems.  But yes, I was aware that there could be clearance issues, which is why I made scaled measurements of the card from a photo I did find online - here

This is very true.  I have the USAS2-L8i plugged into the only PCIe x16 slot on my motherboard, intended, primarily, for Graphics boards..  The only other PCIe slots I have are x1.  In my case, the card comes close to the RAM sockets and there is insufficient clearance to fully operate the RAM ejector handles, although I suspect that I could open them far enough to release the lock and pull the RAM out.

In case it is relevant, the card is rated at 13.5W.

 

As you can see from the photo I linked above, there are no components on the card which would be likely to obstruct in a 16x slot.

I certainly intend to post a photo, but I'm afraid that I've been delayed by sickness and family commitments.

Not quite what you requested, but someone has a photo posted here

Errr.... those are USAS cards, not USAS2.

Oh - well spotted sir!
