Pure guesswork I am afraid but try using a different port because they are controlled by different chips.  Or in the BIOS try disabling the USB Storage Function in Integrated Peripherals. Other than that I can only suggest a BIOS update. You don't say what PSU you are using.

First of all, what's the model of your power supply?

Will the same problem occur if your CPU runs at stock frequency?

Is the powered USB hub connected to the front or rear panel USB port? When the "restart" problem occurs is there any device connected to the powered USB hub?

Try disconnecting few HDDs and one of the graphic card and see if the problem still occurs.
