Installation

WARNING! PCI Express cards, like all computer equipment, can be severely damaged

by static electricity. Be sure that you are properly grounded before opening your

computer case or touching your PCI card. StarTech.com recommends that you wear

an anti-static strap when installing any computer component. If an anti-static strap is

unavailable, discharge yourself of any static electricity build-up by touching a large

grounded metal surface (such as the computer case) for several seconds. Also be

careful to handle the card by its edges and not the gold connectors.

Hardware Installation

external hard drives, etc.). Unplug the power cable from the rear of the power

computer system for details.

3. Locate an open PCI Express slot and remove the metal cover plate on the rear of the

computer case.

4. Gently insert the card into the open PCI Express slot and fasten the card’s bracket to

the rear of the case.

NOTE: If installing the card into a small form factor/low prole system, replacing the

pre-installed full prole bracket with the included low prole installation bracket may

be necessary.

5. Place the cover back onto the computer case.

6. Connect the breakout cable to the large connector on the card.

7. Insert the power cable into the socket on the power supply and reconnect all other

connectors removed in Step 1.
