My setup has a stud hub from klintay  that I modded with a superior psu inside it.

Mine was a usb 2.


He now sells this usb 3.0 version

I do not know if he went to the better psu inside it
but it is easy to upgrade the psu if it is like my hub.
This hub would be sweet with 16 2pacs.  I think you would not need the bridges I use since it is a usb 3.0 hub



I set volts to 5.5 on the psu.

With the bridges I can pull 1.8 amps safely  so 1.8 x 5.5 = 10 watts with ease.

Based on all the work I did with this hub a year or so back running the compacs

I can do  freq 350 non stop with the compacs and a proper fan


the new setup in the garage



both sticks using 2x ports



the first setup only the 2x chip is using the 2x port bridge
