The easiest way to go is to take the cable with the barrel plug that already fits your hub. In other words, cut it off from the wall adapter. Then you'll need the other end, something to connect to you PSU. For that, a cut off Molex splitters work fine.

Then you need to figure out where (+) wire on the barrel cable is. It is usually noted on the wall adapter if (+) is in the centre or on the outer ring. You can use some 1,5 volt battery and some appliance to determine which wire is connected to the outer ring.

On D-Link and Rosewill the (+) wire was marked with long dashes.

Connect red wire to the (+) wire of the barrel cable. Connect the black wire to the (-) wire of the barrel cable.

Double-check the above.

Triple-check the above.

The result will look something like this:

Now, short the green-wired connector to the black one of the ATX PSU to power it up and connect your newly spliced Molex->barrel cable. Connect to the hub. If it seems to work, connect one BE. Still working? Good. Connect the USB cable and try hashing. Connect the rest.

When powering down, ALWAYS disconnect the USB cable first before powering down the hub.

Thanks for the explanation. Im going to try this later this week.

Okay got this far and once again thanks. My next question is what is a safe load to run? If my PSU is rated at +5V 22A it should support 44 erupters. Now that is maxing it out at 110VA I know that cant be okay, so my question is at what capacity can I run this or any PSU? I was thinking of running 35 off it and two fans at 12V .85A so that is just about 80% of the +5V 22A rating. Also will that cause voltage drop because I am pulling more than 5A through an 18 gauge wire?
