can i use a usb3 case with usb2 mobo?

post #1 of 6
Thread Starter 
Im looking at buying an antec 302 but i noticed that it has usb 3 front ports. My motherboard only has usb 2. Will the wires from the case fit the usb 2 header on the board and just run at usb 2 speeds or will i not be able to use the front ports?

I believe the connectors will be completely different.
There are header adapters that will allow you to get a USB 3.0 male header out of your USB 2.0 males on your motherboard - cannot find it sold in Amazon or newegg atm (will update if I will).



Edit: Found this one from Corsair

It is backward compatible,it will run at 2.0 speed.

" Your existing USB 2.0 gear will work on version 3.0 ports and vice versa. You'll be able to maximize your bandwidth when using a USB 3.0 cable with USB 3.0 devices and ports, otherwise plugging a 3.0 device into a 2.0 port or a 2.0 device into 3.0 a port will get you standard USB 2.0 data rates.
Since the new interface has been carefully planned from the start to peacefully co-exist with its predecessor, the connector itself remains mostly the same with the four USB 2.0 contacts in the exact same location as before. Extra pins for the new lanes dedicated to transmit and receive SuperSpeed data are located on the back and only come into contact when mated with a proper USB 3.0 port."

I HIGHLY reccomend NOT getting the Antec 302. $70 isnt to cheap, and this thing lacks a painted inside, and has terrible cable managment features. And Gyro was wrong. The USB 3 header will NOT work with a USB 2 board without a adapter. A USB 3 cable will work with a USB 2port, but a 3.0 header will not go with a 2.0 header. Go with Bitfenix, Corsair, NZXT, or Cooler Master.
