The controller card enables you to connect USB-C Gen 2x2 (20 Gbps) devices to your desktop computer. The USB-C port is ideal for connecting USB devices such as external hard drives and solid state drives or charging and syncing your mobile devices. The USB-C port provides up to 15W (5V/3A) of power and is backward compatible with USB 3.2 Gen 2 (10 Gbps) and USB 3.2 Gen 1 (5 Gbps) devices. Note: USB 3.2 Gen 2 (10 Gbps) is also know as USB 3.1 Gen 2 (10 Gbps), and USB 3.2 Gen 1 (5 Gbps) is also know as USB 3.0 and USB 3.1 (5 Gbps). The USB 3.2 Gen 2x2 card features an ASMedia ASM3242 host controller that utilizes x4 lanes of the PCIe 3.0 bus, making the card capable of speeds up to 20Gbps and enabling fast access to high-performance devices like NVMe drives and SSDs. Review: Super speedy. - Just worked. Easy to install (I panicked because I didn't think I had the right PCIe slot, but it fits in the big one, just doesn't use all of the pins), perfectly compatible without extra drivers in Windows 11. 2x2 is super speedy and was compatible with the drive I needed it for. Very good value. Review: Excellent Expansion Card - Excellent expansion card. I just installed on my Asus ROG Strix G16CHR PCIe 4.0 slot and start the computer. Totally plug and play with Windows 11.0. I connected an UGREEN 40Gbps M.2 NVMe Enclosure and it worked perfectly. Between the enclosure and the expansion card, the USB 3.2 gen 2x2 has, of course, the lowest speed, working with 20 Gbps, that is equivalent to 2.5 GB/s. Testing with DiskMark app, I obtained 2055.07 MB/s for reading and 1845.02 MB/s for writing. ## Features - HIGH PERFORMANCE: Add 1x USB-C SuperSpeed 20Gbps port to your desktop PC with this USB 3.2 Gen 2x2 PCIe Card; Expansion card provides up to 15W (5V @ 3A) to power & charge devices - FULL USB 3.2 GEN 2X2 SPEEDS: Featuring the ASMedia ASM3242 host controller using x4 lanes of PCIe 3.0, this card is fully capable of speeds up to 20Gbps enabling fast access to high-performance devices like NVMe drives and SSDs - MAXIMIZED USB PERFORMANCE: USB Type-C PCI Express card supports Multiple INs to reduce bandwidth loss when mix speed devices are connected to a Hub (hub must also support this feature); UASP support improves performance with storage devices - COMPATIBILITY: Add-on card installs in full or low-profile (bracket incl) PCIe 3.0 x4 slot (Backward compatible w/PCIe 2.0); Windows/Linux/macOS w/auto drivers Win 8 & up; Works w/USB 3.1/3.0/2.0 devices; Does not support DP-Alt mode for video over USB-C ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08T6FCF9S | | Best Sellers Rank | #23 in Internal USB Port Cards | | Brand | StarTech.com | | Built-In Media | "PCI Express USB Card Full Profile Bracket (Installed) Low Profile Bracket Quick-Start Guide" | | Compatible Devices | Personal Computer, Laptop | | Customer Reviews | 4.5 out of 5 stars 258 Reviews | | Hardware Interface | PCI Express x4 | | Item Dimensions L x W x H | 2"L x 3.1"W x 0.9"H | | Item Highlight | USB-C 20Gbps PCI Express 3.0 x 4 Adapter, Data Only, 2x2 | | Item Weight | 1.28 ounces | | Manufacturer | StarTech.com | | Mfr Part Number | PEXUSB321C | | Model Number | PEXUSB321C | | Number of Items | 1 | | Number of Packs | 1 | | Operating System | Linux | | Product Dimensions | 2"L x 3.1"W x 0.9"H | | Style | Classic | | Style Name | Classic | | UPC | 065030891264 | | Unit Count | 1 Count | | Warranty Description | 2 Year Warranty | ## Product Details - **Brand:** StarTech.com - **Hardware Interface:** PCI Express x4 - **Item Weight:** 1.28 ounces - **Product Dimensions:** 2"L x 3.1"W x 0.9"H - **Style:** Classic ## Images ![StarTech 1-Port USB 20Gbps PCIe Card, TAA, Windows/macOS/Linux (PEXUSB321C) - Image 1](https://m.media-amazon.com/images/I/61e7msVSRHL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super speedy. *by J***Y on March 21, 2026* Just worked.
