Power Adapter for USB Hub

Hello,

Couple of months ago, I bought a 4 Port powered USB hub from the local Microcenter, however it didn't come with a power adapter. The power receptacle is labeled:

4 Port USB 2.0 Hub
Input: DC 5.0V, 500 - 1000MA
Rated Power: 2.5W DC5.0V

It is pretty much like the one found at the following site:

The only reasonably priced power adapter I could find was Vohnk AC Adapter from monoprice:

Input: 100-240V 50/60Hz 0.4A
Output: 5V 2.0A

Since the adapter is providing more power than required by the hub, could this flood the USB bus with feedback power and damage my mother board? Any help is appreciated.

Thanks
