Hey,
Can you please post your spec?
Some Motherboards come with USB 3.0 Ports as standard (onboard) and some don't - so we need to know which motherboard you are ordering before confirming this.
If you order a USB 3.0 PCI Express Card, then there will be 2 USB 3.0 Ports on this. There will also be the ports which come as standard on the Motherboard but as mentioned above, different motherboards have different USB Ports as standard
Hope this helps.
will i have any on front?The above specification will come with 2 x rear USB 3.0 ports by default and 6 x rear USB 2.0 ports by default. By adding a USB 3.0 card you will be increasing your total ports the 4 x rear USB 3.0 ports and 6 x USB 2.0 ports.
There will be 2 x USB 2.0 Ports at the front of the case, no USB 3.0 Ports.
