It supports UASP for up to 70% faster transfers, optional SATA/LP4 power connectors for high-powered devices, and is compatible with Windows 10 and macOS. Designed for IT professionals, it offers reliable, high-speed connectivity with a 2-year warranty and expert support. ## Description From the manufacturer Add four USB 3.0 ports with four independent channels, LP/SATA power, and charging support to your PC The 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). 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 (iPhones and iPads) faster than a standard USB 3.0 port. Offers backward compatibility with existing USB 2.0 / 1.1 devices . The USB 3.0 PCIe card is equipped with a standard profile bracket and includes a low-profile/half-height bracke t for installation in small form-factor computers. Review: OK, but overpriced and took a PCIEX16 slot - Card works as described, personally I think it's overpriced, and what wasn't clear is that this card doesn't fit into a small PCIEX1 slot. On my board I only have 4 PCIEX1 slots and 2 PCIEX16 slots (for GPUs). Because the interface on this card is larger than a PCIEX1 slot I had to use my secondary PCIEX16 slot which means it is right up against the GPUs fans which I'm not really happy about. Review: The top of the line - Bought this to run a four-sensor Oculus Rift setup. Was sick of messing around with motherboard USB slots, getting 2.0 connections even on 3.0 ports, etc. - and as I hoped, this card instantly solved all that. Now getting full-speed 3.0 performance from all four sensors with no inconsistencies or problems of any kind. Pricey, but worth it if you want the best. Definitely easier and more reliable than getting a cheaper expansion card and splitting your sensors between that and the motherboard ports. TIPS: - Works plug-n-play with Windows 10 native drivers. I've heard others say the manufacturer drivers make things worse not better, so I never tried. Stick with the natives. - Make sure you have a spare x4-speed PCIe slot on your motherboard, which is the full bandwidth this card uses. Note that this is not necessarily the same as a x4-SIZE slot - check your motherboard manual to find out what speed each slot offers and whether it steals bandwidth from other slots. My MB (like many) has a bunch of x4-sized slots that only run at x1 speed, which would bottleneck this card and defeat the purpose - I had to plug it into the third x16-size slot, which runs at x4 speed. MINOR ISSUES: - Plugging USB cables into the horizontal ports is a very tight fit through the opening for the expansion slot, at least in my case (Thermaltake X5). It's not a problem for me since my Oculus sensors are permanently connected to this card, but might not be great if you plan to use this for stuff that you are plugging and unplugging regularly. - The small heatsink on my card was attached very sloppily - visibly on a bit of an angle, not straight and flush with the card. Still makes full contact with the chip underneath so there's no functional issue at all, and I may have just gotten a one-in-a-million bad draw. Was slightly disappointing for such a high-end card, but not enough so that I'd bother returning it for a replacement. ## Features - HIGH-PERFORMANCE EXPANSION CARD: Increase the efficiency of your USB 3.0 devices with four dedicated USB 3.0 channels and up to 5 Gbps of bandwidth per channel with this 4 port USB 3.0 PCIe card - POWER & CHARGE: Use this USB 3.0 add on card to power high-powered USB devices as necessary, with the optional LP4 or SATA power connector - MULTI-USE USB CONNECTOR: Connect additional external hard drives, VR headsets, game controllers, digital equipment and more to your computer by connecting this USB adapter card through an internal PCI Express slot - USB 3.0 WITH UASP SUPPORT: This PCIe to USB adapter card lets you experience speeds up to 70% faster than traditional USB 3.0 when used with a UASP-supported enclosure - THE IT PRO'S CHOICE: Designed and built for IT Professionals, this 4 port USB 3.0 PCIe card is backed for 2-years, including free lifetime 24/5 multi-lingual technical assistance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00HJZEA2S | | Best Sellers Rank | #39,030 in Computers ( See Top 100 in Computers ) #24 in USB Port Cards | | Brand | StarTech | | Built-In Media | Low-profile bracket, USB adapter | | Compatible Devices | Personal Computer | | Compatible devices | Personal Computer | | Customer Reviews | 4.2 out of 5 stars 633 Reviews | | EU Spare Part Availability Duration | 2 Years | | Global Trade Identification Number | 00065030854627, 00115971579681 | | Hardware Interface | USB 3.0 | | Hardware interface | USB 3.0 | | Item Dimensions L x W x H | 16.8L x 1.5W x 11.9H centimeters | | Item Type Name | USB Adapter | | Item Weight | 0.09 Kilograms | | Item weight | 0.09 Kilograms | | Manufacturer | StarTech.com | | Mfr Part Number | PEXUSB3S44V | | Model Number | PEXUSB3S44V | | Operating System | Windows 10, macOS | | Product dimensions | 16.8L x 1.5W x 11.9H centimeters | | Style | PCI Express | | Style Name | PCI Express | | UPC | 115971579681 012303035535 012300273299 132018237366 929573526550 650308546276 012304744221 888228027692 803982819444 545070914333 014445023128 042111645060 065030854627 | | Unit Count | 1 Count | ## Product Details - **Brand:** StarTech - **Hardware interface:** USB 3.0 - **Item weight:** 0.09 Kilograms - **Product dimensions:** 16.8L x 1.5W x 11.9H centimeters - **Style:** PCI Express ## Images ![com 4 Port USB 3.0 PCIe Card w/ 4 Dedicated 5Gbps Channels (USB 3.2 Gen 1) - UASP - SATA / LP4 Power - PCI Express Adapter Card (PEXUSB3S44V) | Optional Molex SATA Power, Four Dedicated USB Channels - Image 1](https://m.media-amazon.com/images/I/71qZQ8nTThL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this card backwards compatible with PCIE - x1?** A: Since this question, and the answer by D. Brown were posted in 2014, this listing seems to have changed to include a large variety of individual cards (without giving each its own individual questions), resulting in the confusing associated comments posted years later. Even the information posted with a specific card is scrambled, as, whith the PEXUSB3S44V card selected, the 'Specifications Sheet' document linked refer to the Model# PEXUSB3S4V card, with the following specifications: " 4 Port PCI Express PCIe SuperSpeed USB 3.0 Controller Card Adapter with UASP - SATA Power Connector Type(s) 1 - PCI Express x1 Male External Ports 4 - USB Type-A (9 pin) USB 3.0 Female Internal Ports 1 - SATA Power (15 pin) Plug OS Compatibility: Windows® XP, Vista, 7, 8, 8.1, 10 Windows Server® 2003, 2008 R2, 2012, 2012 R2, 2016 Note: The maximum throughput of this card is limited by the bus interface. If used with PCI Express Gen 1.0 enabled computers, the max throughput is 2.5 Gbps. If used with PCI Express Gen 2.0 enabled computers, the max throughput is 5 Gbps. " While the 'User Manual' linked is for the Model# PEXUSB3S44V card, which has markedly different requirements: " 4 Port PCI Express USB 3.0 Card with 4 Dedicated Channels - UASP - SATA/LP4 Power • Available PCI Express x4 or higher (x8, x16) slot • A SATA or LP4 power connector (optional, but recommended) • Windows® Vista, 7, 8, 8.1, 10, Windows Server® 2008 R2, 2012, 2012 R2, Linux 2.6.31 to 4.4.x LTS versions only " Obviously, here, the latter is correct, but, troublingly, given the large number of items included on this page, ALL of the answers and specifications listed are correct, just each for different products that were thoughtlessly merged into a single listing. **Q: Is this card faster than "standard" USB 3.0 PCI cards, at least enough to justify the price? Or is it's main feature the that it has ind. channels?** A: Most usb 3.0 cards have once channel that all the ports share, the same as plugging in a USB hub into a one-port card.. This one 4-lane card effectively has 4 conventional 1-lane cards in it. This makes it faster overall when devices are used simultaneously. Assuming the flavor of your expansion slot can handle the bandwidth, that is. **Q: Would you advise using both LP4 and SATA power connectors?** A: Hi, We would only recommend one or the other. The PEXUSB3S44V would not receive any extra power if you used both SATA and LP4 at the same time.Thank you, NickStarTech.com Support **Q: Does it have EFI firmware and boot on a Mac?** A: Hi,This card does not support Mac operating systems.Let us know if you have any other questions.Thank you, NickCustomer SupportStarTech.com ## Customer Reviews ### ⭐⭐⭐ OK, but overpriced and took a PCIEX16 slot *by R***O on 11 September 2021* Card works as described, personally I think it's overpriced, and what wasn't clear is that this card doesn't fit into a small PCIEX1 slot.

Facile d'installation, bien prendre les pilotes Windows. Par contre sur le port PCI Express 4x le produit n'était pas bien reconnus. Je l'ai mis sur le PCI Express 8x (pour du 4x) et la tout à bien fonctionné. Je recommande pour ceux qui ont des problèmes avec l'oculus. ## Frequently Bought Together - StarTech.com 4 Port USB 3.0 PCIe Card w/ 4 Dedicated 5Gbps Channels (USB 3.2 Gen 1) - UASP - SATA / LP4 Power - PCI Express Adapter Card (PEXUSB3S44V) - TEAMGROUP Elite DDR5 32GB Kit (2x16GB) 5600Mhz PC5-44800 CL46 Non-ECC Unbuffered UDIMM 288 Pin PC Computer Desktop Memory Module Ram Supports Intel & AMD TED532G5600C46DC01 - TEAMGROUP MP33 2TB SLC Cache 3D NAND TLC NVMe 1.3 PCIe Gen3x4 M.2 2280 Internal Solid State Drive SSD (Read/Write Speed up to 1,800/1,500 MB/s) Compatible with Laptop & PC Desktop TM8FP6002T0C101 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/289044035-com-4-port-usb-3-0-pcie-card-w-4](https://www.desertcart.ec/products/289044035-com-4-port-usb-3-0-pcie-card-w-4) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-24*
