I have this slot on my old motherboard (one on the far left)

and I'm in need for USB3. I was wondering maybe it is some kind of PCI slot that I can attach USB3 card on and was hoping someone here would know. There are no PCI-E or any other slots on it, just this and 2 graphic card slots that can be seen next to it.
I have this card

but I'm pretty sure it's unusable in this case. Would really appreciate any help

what motherboard is it? we can find manual and look if we lucky.

think it says its PCI underneath it
its labelled PCI J20, and on this HP it is PCI x8 (x4 performance)
https://support.hp.com/au-en/document/c00724864

seems its common label for PCI slots on HP devices, for example: Two 32-bit/33-MHz 3.3V PCI slots (J20 to J21)

its not pci express, its the older type.

add on card won't work there.

Your card is a PCI Express add on, the slot is only PCI.

It won't work there

J20 is a common name for PCI slots on HP servers and business machines. From what I can tell.

edit: might be wrong link
