Power Adapter for USB Hub Tags: Power Adapter USB Power Components Last response: September 15, 2010 7:28 AM in Components Share ukhanlists September 8, 2010 12:48:14 AM 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: http://www.meritline.com/1-6m-usb-hub-warm...x?source=f... The only reasonably priced power adapter I could find was Vohnk AC Adapter from monoprice: http://www.monoprice.com/products/product....=1&format=... 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.

This adapter doesn't have a ground terminal and both the positive and negative terminals are the same size(width wise), so it can be plugged in two different ways. m 0 l Can't find your answer ?
