USB Power Surge

[laserblazer]

I just put a PCI-e USB3 card that I got on Ebay into my system. The supplied drivers didn't work, so I found some for another card that uses the same NEC chip. This installed ok and device manager is happy but I got "Power Surge on Hub" message, even with no device plugged in. The board has a connector the same as on floppy drives. The psu lead is not long enough to reach the card, so I can't try it. It's a 1 lane card, so is that why it isn't getting sufficient power? If I can extend the floppy power lead, should that fix it?

I expect that yes that card will need the extra power connector to be able to operate correctly.
