Hi, I want to buy a Gigabyte Wifi/Bluetooth card, but it needs a USB connector to power it (I think), but my MoBo's USB connectors are all being used, one for my H80i fan and the other I think for my hard drive. Is there like an extention cord type thing that allows me to connect more USB cords? Please note that I'm talking about the USB connector inside the case, not the USB port on the outside. I use an Asus Sabertooth 900FX R2.0 mobo.
