USB 2 port on case connected to USB 3.0 header in Motherboard

Hi guys,

I am currently trying to build my first PC build from scratch and I just wanna ask if a USB 2.0 port(from case) still perform like a USB 3.0 if it is connected to the USB 3.0 internal header of my Mother board.

Or will that USB 2.0 port(receptacle on the case, the non-blue one) limit my transfer speed and thus making the internal USB 3.0 header of my MoBo pointless to have?

Hoping for this to be clarified. :)
Thanks in advance!

    They are different header sizes, your choices are 2.0 to 2.0, 3.0 to 3.0, or using adapters.
  2. Hi @Gam3r01

    I think USB 3.0 and USB 2.0 type A has the same sizes. Only the color blue on the USB 3.0 and its transfer speeds are different.
  3. 3.0 carry the 20 pin connector, 2.0 are 9 pin.
  4. @Gam3r01, Oh! Okay so the female pins from the USB 2.0 pins of the case only has 9pins while the USB 3.0 internal male header of my MoBo has 20 pins, right?

    Thanks bro!

    But, how do I go about it if I want a case that can utilize the USB 3.0 from my MoBo? Can I change the USB port on the case? or should I just find a case that offers this USB 3.0 port out-of-the-box?
  8. You can make 2.0 work on 3.0, and the other way around, however to get 3.0 speeds it has to be a 3.0 to 3.0.
