Help Me With # of USB Headers and Case

Hello Everyone!
I am new in the pc building scene and am thinking up a build. I am thinking of buying the ASUS ROG STRIX Z270F GAMING Motherboard and the Phanteks Enthoo Pro Case. My questions are:
1. Will my motherboard support the 2 USB 2.0 and 2 USB 3.0 ports on the top of the case
2. How exactly do USB headers work? Can 2 or more USB ports be usable through 1 header, or is it one to one?
Thanks!

    1. Yes, the Asus Z270F motherboard will support the 2x USB2.0 and 2x USB3.0 of the Phanteks Enthoo Pro case. The motherboard has a total of 3x USB2.0 (9-pin) Internal Headers (supports up to 6x USB 2.0 ports) and 1x USB3.0 (19-pin) Internal Header (supports up to 2x USB 3.0 ports).

    Such USB internal headers look like these:

    The one set of 19-pin header marked "USB3_34" is your motherboard's USB3.0 header, the three sets of 9-pin headers marked "USB1314" (part of the ROG_EXT), "USB910", and "USB1112" are your motherboard's USB2.0 headers.

    2. Each internal USB header supports two USB ports (not one-to-one). Your Phanteks Enthoo Pro case would have included cables connected to such ports that looks like this:

    The larger 19-pin cable is connected to the 2 USB3.0 ports of your case. You plug this 19-pin cable to the 19-pin USB3.0 header of your motherboard.
    The smaller 9-pin cable is connected to the 2 USB2.0 ports of your case. You plug this 19-pin cable to any of the three USB2.0 headers of your motherboard.
