USB 3 Power Surge

Recommended Posts

Recently got a Transcend USB 3 controller card.

Installed in the motherboard fine, attached the Molex Power Lead.

Every time I boot my computer the controller fails with 'Power Surge on Hub Port'

Driver version is

Firmware of the controller is 4015.

Installing on an ASUS P5Q-E under Windows 7 x64

Any ideas???

Ok, fixed it!

It could have been one of the two:

I reseated the card, and also gave it power directly from the PSU via a new cable - before it was connected to a molex that was also powering other devices.

I'm going to say it was the power cable, giving it a direct feed with no other devices running off it.
