Product Overview

High Performance & Versatility

The PEXUSB3S4V PCI Express USB 3.0 Card (with SATA Power) adds 4 external USB 3.0 ports to any PCI Express-enabled computer system with support for data rates up to 5 Gbps, while remaining backward compatible with USB 2.0 / 1.x devices.

Increased Transfer Speeds

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimises transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. See our UASP test results below for further details.

Expertly Designed

The card uses a "stacked" port layout that places the ports one on top of the other, enabling all four USB 3.0 ports to be external facing, while still allowing the card to fit into a small form factor/low profile computer system using the included low profile bracket.

• 4 external USB 3.0 ports in a stacked layout.
• UASP support for more efficient data transfer.
• Fully compliant with USB 3.0 revision 1.0 specifications and Intel xHCI rev0.95 specifications.
• Built-in optional SATA power connector for bus-powered USB devices.
• Optionally provides up to 900mA per USB port.
• Backward compatible with USB 2.0 and USB 1.0/1.1 devices.
• Compliant with PCI Express 2.0 specifications.
• Includes a Low Profile/half-height installation bracket.

A motherboard’s main job is to act as a conduit between the various hardware elements that make up a PC. It needs to be able to link the desired CPU(s), system memory, graphics card, hard drive(s), and add-in cards and enable them to work in harmony.

Read More 4 Port PCI Express USB 3.0 Card, 900mA USB Power Per Port, SATA Power Connector, PCIe 2.0 is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from High quality, hassle free but a tight fit I chose this pricier powered USB 3 card hoping to avoid installation hassles. Once my W7 PC found the driver disk (included) everything installed with no problem at all and it seems to be working well so far. Have got some heavier USB loads like a USB TV dongle working satisfactorily. Also hope it will cure USB problems with a Logitech keyboard. Needed a SATA - Molex converter lead for power (only needed if driving heavier loads). Worth pointing out that the vertical stacked mode of USB ports were a very tight fit behind the slots of my (Corsair) system box. You may need to jiggle the bracket a little to align it, as I found the slot aperture on mine was such that you could barely insert a USB plug due to the steelwork of neighbouring slots interfering with access to the USB ports themselves. USB plugs are a tight fit and take up the width of the slot, but they do still work satisfactorily.
