Installing a USB3 PCI-e Card

Kido

I can't find anywhere to connect the PSU. The instructions also don't say anything about attaching the PSU.

Have you looked for it in the device manager? Could be broken, Scan have a forums page here which might get you going.

It doesn't show up in the device manager. I'm suspecting it's a faulty card, so I'll take it back after work tomorrow. Good job I don't live too far away.

to a separate power supply (as per,say, an extra hard drive).

The usb has a power connecter itself (all those clever usb accessories!) and needs extra power above the ampage that the expansion slot has available.
good luck

What made you come to that conclusion?

Hard-drives aren't connected to separate PSUs, they are powered from the system PSU.

Are you suggesting that that a separate power supply other than the main PSU is required?!

I think he meant a separate power connection rather than taking juice just from the PCI connection, although looking at the picture & the description on Scan's site it doesn't need 1.

When I fitted a USB3 card to my XP system it not only needed an expansion slot but also needed a power connection (from the system power supply) to the board, just as when you add a hard - drive, say, you need to plug a power supply into it as well as the IDE ( or SATA) connection. Hence my first post. When I found a detailed picture of the actual board under discussion, I posted that as I could not see a power supply connection.

I'm still puzzled, however, how the board will get enough ampage from the expansion slot alone, if there are 4 USB3 devices all plugged in demanding power. Perhaps someone who knows the specification of PCI - express slots can post an answer to this. I know that some gaming setups with big graphic boards have special power supply arrangements.

Non of the above however, helps to explain the OP question.
