Dell Optiplex 9020 SFF Bluetooth question

Recently bought a Dell Optiplex 9020 SFF, then found it doesn't have Wifi.

Day 1, the power supply packed up! Replacement in the mail.

Have bought a tp-link AC1200 Wi-Fi Bluetooth 4.2 PCIe Wifi/Bluetooth card/adapter.                

Am I right in thinking that if I don't plug in the USB connector from the Wifi card,

I will get my Wi-Fi connection but sacrifice Bluetooth? I can live without Bluetooth.

The 9020 SFF appears to have only 2 internal USB ports, both of which are in use as front panel connectors.

Thanks for any and all advice!
