Adding a second PCI Express slot to a Mini-ITX motherboard?

[Deleted member 1218011]

I have a Mini-ITX motherboard, so I have only one PCI Express slot. I would need a second one though, are there any adapters/converters that would allow me to add an extra one?

I have never come across one. It would be better just to get another board. Looks like mITX is not your correct form factor.

No.

What do you need to put in the second slot? You can get many mITX boards with WiFi/Bluetooth built in.

I would need to put a RAID controller in it. The current one already has an extra NIC in it.

Yeah... if you need more HDDs than the board can handle, m-ITX really isn't for you.

How much do you need the extra NIC?

mITX boards are what they are, limited expand ability and just come with the essential expansions. If the motherboard raid is not enough I suggest replacing the board with at least a mATX board.

Quite a bit actually, since ESXi does not support the built-in one.

This is a test lab, I was just wondering how far I can take a mini-ITX build in this scenario, but apparently not much

mITX boards are what they are, limited dependability and just come with the essential expansions. If the motherboard raid is not enough I suggest replacing the board with at least a mATX board.

In which way are they less dependable?

That was misprint auto correction! Been fixed now to expand ability!

Ahah ok makes more sense now

Yes, is the answer to your question !. I found one on Ebay... here it is. http://www.ebay.co.uk/itm/262371498163 It connects to your motherboard via the SFF-8643 connector, which most of the new Mini ITX boards have.

There are also PCIE nultiplex boards available, but they reduce the band width. So a single PCIEx16 becomes 4 x PCIEx4. However, if you want to use one of the slots for a PCIE SSD, your far better just getting one of the Intel 2.5" versions with an adapter which connects directly to the SFF-8643.
