USB 3.1 connector

SATA power connector

USB cards can be severely damaged by static electricity. Make sure 

that you’re properly grounded before you open your computer case 

or touch your USB card. You should wear an anti-static strap when 

you install any computer component. If an anti-static strap isn’t 

available, discharge any built-up static electricity by touching a large 

grounded metal surface for several seconds. Only handle the USB 

card by its edges and don’t touch the gold connectors.

1.  Turn off your computer and any devices or peripherals that are 

connected to it (for example, printers, external hard drives, and 

so on).

2.  Unplug the power cable from the back of your computer.

3.  Disconnect any peripheral devices that are connected to your 

computer.

4.  Remove the cover from your computer case. Consult the 

documentation that came with your computer for details about 

how to do this safely.

5.  Locate an open PCI Express slot and remove the corresponding 

metal cover plate from the back of your computer case. Consult 

the documentation that came with your computer for details 

about how to do this safely. This card works in PCI Express slots of 

additional lanes (x4, x8, or x16 slots).

6.  Gently insert the card into the open PCI Express slot and fasten 

the bracket to the back of the case.

Note: If you install the card into a small form factor or a low-profile 

desktop system, it may be necessary to replace the preinstalled 

standard-profile bracket with the included low-profile (half-height) 

installation bracket.

7.  Connect a 15-pin SATA power connector from your computer’s 

power supply to the SATA power connector on the card.

8.  Place the cover back onto your computer case.

9.  Reconnect the power cable to the back of your computer.

10. Reconnect all of the peripheral devices that you disconnected in 

       step 3.

11. Turn on your computer.

Note: If a power source isn’t connected to your USB card, your 

system won’ t recognize it.

The available bandwidth (x Gbps) is shared equally between the two 

ports.
