I have just purchased a pcie wireless/bluetooth card and it has a connector that goes to the usb 9 pin. The problem is, my motherboard only has 1 9 pin and 1 4 pin, and the case usb ports also have a 9 pin connector. Now, i have noticed that there is only 2 wires connected in the 9 pin female connector that came with my pcie card, so can i plug it into the 4 pin? that would save me from trying to purchase a splitter or going without usb ports in the front of my case
