USB 3.0 ports on case and mobo question

Hi all, this may be a stupid question but if a case says it has 4x USB 3.0 ports (not the situation with this particular case below), yet the motherboard only has 2x USB 3.0 ports, then I would only end up with 2x USB 3.0 ports, correct?

Also, when buying a case does it need to have USB 3.0 ports listed in the specs (not USB 2.0) in order to utilize the ones on the motherboard?

  1. It depends on the case and the mobo.

    Some cases just use a USB extension cable to hook up the front panel connectors to the USB ports on the mobo.
    IIRC, the carbide series use a proper USB 3.0 header though that will connect to the motherboard header (only newer boards have this)

    basically, the board you linked DOES have a 3.0 header, so assuming the case does connect via that, you will get its full compliment of USB 3.0 ports AS WELL AS the ports directly connected to the mobo.

    you may want to double check if the case DOES use the header though, but i would expect a corsair carbide case to have that feature.

    EDIT: the newegg link clearly states it connects to a header, so yes, you will get the extra USB ports.
