Reddit mentions of USB 2.0 Internal Motherboard Header Cable - 20"

Edit: After looking at the card you're using, you might be better off with a regular USB header cable. This won't have the locking connector on the motherboard end of the cable and will also be keyed (one of the pins is blocked off) so it'll be easy to install without messing anything up.

Good news! I actually found a cable that should fit your card (mostly). You should know that cable won't work without rearranging the wires on the "USB" end. As it stands, it looks like it's wired backwards from the cable in the image you shared. That said, this process is super easy (follow the steps in this video) and if you're careful, shouldn't take more than 5 minutes.

If you go this route, you could also buy yourself one of these keyed connectors for another couple bucks to make the cable identical to the one in your picture.

To make sure the cable is wired correctly, just make sure the colors on the wires are paired the same way they are in the picture. Let me know if that doesn't make sense, I can try to explain it better.

Are you any good at soldering?

Kinda expensive and pointless to me though 2.0 is not worth

That looks like a usb header to the motherboard. I do not know if the pinout is the same on both sides but if it is it should be a commonly found usb header to usb header cable. This is just a wild guess but only one way to find out.

This should work perfectly fine for 2.0. I’ve seen some other options that are pricier and they’re those weird off-brands that do exactly the same thing and honestly look of a poorer quality. With NZXT you’re getting quality and a trusted name brand with both warranty and support. However it doesn’t say in the packaging specs it includes the female to female USB header cable that bridges the hub to the motherboard. I could be wrong but just in case one like this should do you just fine.

Edit:
According to Amazon this cable is frequently purchased with the NZXT USB header hub so I’m gonna say NZXT probably doesn’t included one.

Actually. I think you need a [USB Header Cable](

However the Phobya one should be fine using my original method. (I use that method on my Swiftech MCP50X)
