    HELP!! Is there a away to turn up USB header voltage on z97 Hero VII?

    Hello all,

    I have a z97 Hero VII and want to plug in my Corsair k95 motherboard to the FRONT USB header and use the USB pass-through on the keyboard for my Corsair M95 mouse. I currently use a Corsair 600T Case but will be switching to a 760T. I was able to accomplish this with my old Asus z87-A motherboard with no issues, but on this motherboard I hear the computer recognize that something has been plugged in but there seems to not be enough power on these front ports to power the mouse through the USB pass-through.

    - I have tried all the USB 2.0 and the one 3.0 ports on the front for the pass-through with no success.
    - I have used a USB cable from the back to connect to the USB 3.0 cable on the front, still with no success.
    - If I use the USB ports on the back, it works just fine.
    - Yes I kinda need this to work in this configuration due to how my system is laid out.
    - The manual states there is a consistent 5.0v going through the front headers, but i'm sure there is some slight drop off when you add the connector to the front panel and then the K95 pass-through cable.

    Finally, if there is no way to turn up the USB voltage, would a powered USB hub be a reasonable solution? I say powered because I'm suspecting a normal USB hub would have similar issues, even if plugged into the back. A powered USB hub should supply 5.0 v directly with no additional wires sapping voltage.

    I guess what I'm wanting to know is if anyone has had a problem with USB voltage decrease from the USB 3.0 cable that goes from the motherboard to the front panel USB 3.0. If so, then I may have to go with the powered USB hub.

    So, what do you all suggest?

    is there a power cable to the front base USB connectors??
    like sata or molex?
    inside bios you can "boost" it a lill but its only aimed for charging cell phones but you can try it at own risk.
    dont know where it is on thhat gen mobo but take a look in the manual under USB and under recharge or if there is enny thing similar.

    USB voltage should all be set at 5 volts. Switching the boost on, only increases the available current slightly.

    I ended up fixing the issue with this little gadget:

    NZXT IU01 Internal USB Expansion Module

    It plugs directly into the power supply via a molex connector and there is zero degradation of voltage and everything works perfectly now. It is amazing that only NZXT thought of this little product cause it is both amazing and works perfectly.
