so my 90w psu is only giving me half that?  I have a new psu coming to try. I also have a spare atx psu around here is someone can walk me thru splicing it in..  can I assume that the volts are being decreases in the hub when the power is split so it inputs 12v and outputs 5v at the ports?  how can I get the amps I need to fully populate this!!! im getting desperate!!!
