Product description

Capacity:4 Ext Quad Bus  |  Style:PCI Express

Add four USB 3.0 ports with four independent channels, LP/SATA power, and charging support to your PC through a PCI Express slot. The PEXUSB3S44V 4-port PCI Express USB 3.0 card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC. This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers. When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. By employing four host controller Chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps. 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 optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. For high-power USB devices, this PCIe USB 3.0 card includes an optional SATA or LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0). the USB 3.0 card also supports USB battery charging specification 1.2 (Apple mode only), letting you charge compatible Apple devices (I phones and iPad) faster than a standard USB 3.0 port.

5.0 out of 5 stars Great Product, Highly Recommend.
By Adam Higgs on 21 May 2020
I have a racing simulator and VR setup; even though I have enough physical ports when using hubs, my Z97 motherboard did not have enough channels to run everything without issues; particularly with my older Rift CV1 requiring multiple channels for base stations. This product worked perfectly out of the box and solved those issues.
I have since upgraded to a Rift S, and on-sold this card.

Reviewed in the United Kingdom on 5 September 2021
The biggest problem with so called USB PCI-E expansion cards, is they're all on a single controller. so the 5Gb bandwidth is shared between the 4, or even 7 ports.. Avoid these and get the correct card.

Instatly when I installed this card, I plugged in 4 Logitech C920's (make sure to uninstall the Logitech drivers, they're horrific, use the generic win7/8/10 UVC ones) and they all worked.

I have two PCIE16x and two PCIE8x slots, one PCIE16x is taken up with the GPU, but the other 3 are now fair game!

I plan on expanding my live streamed show (After Hours) to add even more webcams.
This is the card tech/muso people. It delivers. Avoid all the cheap £20-40 cards and do it properly!
Thank you Startech!
