Sorry, not sure where to post this but I have a low profile case with no USB 3 ports, but I have a single free PCI-e slot and a free Sata power plug (although it is an extension and therefore also being used to power an HDD). Are there any PCI-e expansion cards (obviously low profile) for this? I don't need it to be fast charging or high power, only the transfer speed, so if it works without external power then it would be fine.
