Manufacturer description
The StarTech.com 4-Port USB 3.0 PCIe Card adds four USB-A ports to a desktop PC through one internal PCI Express slot. Most add-on cards split one USB controller across every port. This card gives each port its own dedicated controller and a separate 5Gbps channel (USB 3.2 Gen 1). You can run an external hard drive, a VR headset and a game controller at the same time, and each one keeps its full bandwidth. If you use external storage, the card supports UASP (USB Attached SCSI Protocol). Paired with a UASP-capable enclosure and a compatible operating system, StarTech rates it up to 70% faster…
SpecPicks Verdict
SpecPicks scored StarTech.com StarTech 4-Port USB 5Gbps PCIe Card using a rating × review-volume × price-fit model applied to published specs and reviews across the expansion cards category. StarTech.com's expansion cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for expansion cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Does each port on this StarTech card get its own bandwidth?
Yes. Each of the four USB-A ports has its own USB controller and a dedicated 5Gbps channel, so devices on different ports do not share bandwidth.
What USB standard does the card support?
It supports USB 3.0, also called USB 3.2 Gen 1, at up to 5Gbps per port. It does not provide 10Gbps USB 3.2 Gen 2 speeds.
Do I need to connect a power cable to the card?
The SATA or LP4 power connector is optional. Connect one from your power supply when you plan to run high-powered USB devices such as external hard drives or VR headsets.
How do I get the UASP speed boost?
You need a UASP-supported drive enclosure and an operating system that supports UASP. With both in place, StarTech rates transfers up to 70% faster than conventional USB 3.0. Check the product listing for supported OS versions.
What warranty comes with the StarTech 4-port USB 3.0 PCIe card?
StarTech.com backs the card with a 2-year warranty, plus free lifetime 24/5 multilingual technical assistance.
