Introduction
The PEXUSB3S400 PCI Express x4 USB 3.0 Card (with SATA Power) adds 4 independent
external USB 3.0 ports to any PCI Express x4-enabled computer system. SuperSpeed
USB 3.0 provides up to 5 Gbps of data bandwidth, while remaining backward
compatible with existing USB 2.0 devices at 480Mbps.
With each port being indpendent, full bandwidth is available per port, instead of
shared between ports. This allows for maximum transfer rates if multiple devices are
connected.
Using a “stacked” port layout that places the ports one on top of the other, more ports
are able to t into a smaller space. This 4-port PCIe x4 USB 3.0 adapter enables all four
USB 3.0 ports to be external facing, while still allowing the card to t into a small form
factor/low prole computer system.
Plus, with a built-in SATA power connector, each USB port can provide up to 900mA of
power to devices that draw power from a host bus connection (500mA for USB 2.0) by
connecting to your computer power supply.
The PEXUSB3S400 USB 3.0 PCIe x4 card is backed by a StarTech.com 2-year warranty
and free lifetime technical support.

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 Express 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 PCI Express card by its edges and not the gold connectors.
Hardware Installation
1. Turn your computer o and any peripherals connected to the computer (i.e. Printers,
external hard drives, etc.). Unplug the power cable from the rear of the power
supply on the back of the computer and disconnect all peripheral devices.
2. Remove the cover from the computer case. See documentation for your computer
system for details.
3. Locate an open PCI Express x4 slot and remove the metal cover plate on the rear of
the computer case (Refer to documentation for your computer system for details.).
Note that this card will work in PCI Express slots of additional lanes
(i.e. x8 or x16 slots).
4. Insert the card into the open PCI Express slot and fasten the 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. OPTIONAL: Connect a 15-pin SATA power connector from the computer’s power
supply to the SATA power connector on the card. This is only required if using the
ports with bus-powered USB devices (no external power adapter) or if experiencing
connectivity issues.
6. Place the cover back onto the computer case.
7. Insert the power cable into the socket on the power supply and reconnect all other
connectors removed in Step 1.
